The Ouster TOP sends and receives data with an Ouster Imaging Lidar, converting to point cloud data on the . For more information see the user guides at Ouster.io\nRequirements:\n\nThe currently supports Ouster devices using version 2.x firmware. Devices that require version 3 firmware are not currently supported.\nAccess to your local network to connect with the sensor device. Check your firewall settings if you have trouble accessing the device.\nHigh resolution scanning modes require up to 130Mbps of bandwidth. Gigabit Ethernet hardware is required for full operation. Insufficient bandwidth will cause broken images and missing frames.Features include:\n\nAdditional sensor data like IMU (Inertial Measurement Unit - the gyroscope and accelerometer), packet counts, matrices via Info and Info .\nVisual Panoramic and Scan Order capture formats selectable in 'Image ' parameter.\nFlexible X, Y, Z, Range, Intensity and Noise plane mapping to RGBA Image Channels\nTime Sync Mode for supporting multiple devices in the same area (Internal OSC, Sync In, PTP 1588)\nAuto startup featuresConnection Instructions:\nTo connect to the sensor, you will need either the IP addressed assigned by the local DHCP server or the name of the device. The name is based on the serial number that is usually printed on the top of the sensor in the format \"os-############\". This name can be entered directly into the Device Address parameter (see parameter help below). You can also connect to the device through a web browser using the IP or name in the format http://os-###########/. The web interface allows you to check the status of the device and gives additional error information.\nOnce the device is configured, it will continue to send output to the target IP address so it is not required to enter the device address again unless you need to change the configuration.\nRange data collected from the device is presented as 32bit floating point values in the RGBA channels of the output image. Output can be arranged either in chronological scan order or as a panoramic image using the Image parameter. IMU data from the device can be accessed by connecting an Info CHOP. If more than 4 output channels are needed, you can use a Ouster Select TOP to create additional output images.\nNote: All 3D coordinates are transformed into TouchDesigner space where Y is up and X and Z represent the ground plane. This is different from the original coordinate space defined in the Ouster documentation.\nThe lookup tables used to convert the range values into 3D points can be accessed with an Info DAT.\nSee also: Ouster Select TOP\nousterTOP_Class\n\nContents\n \n \n \n \n \n \n \n \n \n \n\n\n\n\n\n active - Enables connections with the device.\n\n\n\n deviceaddress - The IP address or the name of the Ouster device. The address is only required during configuraton. The device will request an address from the local DHCP server when it is connected to the network. The name of the device is printed on the top of the sensor in the format \"os-#####\", where ##### is the serial number e.g. \"os-991900123456\". You can determine the IP address using the ping command and the device name e.g. ping -4 os-991900123456. For more information see the Ouster User Guide at Ouster.io.\n\n\n\n lidarport - The UDP port number to receive lidar data.\n\n\n\n imuport - The UDP port number to receive data from the inertial measurement unit (IMU) on the device. The IMU data can be accessed by connecting the Ouster to an Info CHOP.\n\n\n\n commandport - The TCP/IP port number to use to send configuration commands to the device.\n\n\n\n targetaddress - The IP address where the sensor should send the lidar and IMU data to.

This field should only be necessary if the sending machine has more than one IP address or if you wish to send the lidar data to a different machine than the one you are configuring it on.\n\n\n\n localaddress - An IP address for the current machine that should be used to connect to the device with. If the address is left blank, the default network address will be used.\n\n\n\n scanmode - - Select a scanning mode to set the sensor's horizontal resolution and number of revolutions per second. The vertical resolution is determined by the hardware e.g. an OS1-64 sensor has vertical resolution of 64 pixels (samples).\n\n mode512x10 - mode512x20 - mode1024x10 - mode1024x20 - mode2048x10 -\n\n configdevice - Enable this toggle to have the Ouster set the configuration properties of the device. If the device has already been configured to the correct mode and network connections than this can be disabled to save some processing time.\n\n\n\n\n\nThe Output page allows you to select what data is placed in the 's output image. Range, Intensity, Reflectivity and Noise are raw data channels coming from the sensor, while XYZ position values are calculated by using the range data and the look up table of beam azimuth and altitude angles. Range is measured in millimeters, while XYZ positions are in meters. If you need more than 4 channels of data, use a Ouster Select TOP to create a second output image from the same sensor data.\nIn addition to the sensor data, you can also assign a constant value of one or zero to a channel by selecting the corresponding entry from the menu. Selecting 'Active Mask' from the channel menu will output a one if the pixel represents valid sensor data or a zero if it is padding (when the image contains more pixels than there is available sensor data). The mask channel can be used in the Geometry COMP Active instance channel to control which points are used for instancing.\n\n layout - - Use this parameter to determine how data is arranged in the output image. The layout of data is generally not important when used as a point cloud.\n\n pointcloud - Sensor data is arranged chronologically in a square texture according to when it was received by the scanner. If there are fewer points than pixels in the image, the remaining pixels are filled with the floating point value NaN. image - In panoramic mode, the samples are arranged to form a continuous picture of the area around the sensor.\n\n redchannel - - Select what sensor data will be placed into the red channel of the output image.\n\n x - y - z - range - intensity - reflectivity - noise -\n\n greenchannel - - Select what sensor data will be placed into the green channel of the output image.\n\n x - y - z - range - intensity - reflectivity - noise -\n\n bluechannel - - Select what sensor data will be placed into the blue channel of the output image.\n\n x - y - z - range - intensity - reflectivity - noise -\n\n alphachannel - - Select what sensor data will be placed into the alpha channel of the output image.\n\n x - y - z - range - intensity - reflectivity - noise -\n\n\n\n timemode - - Select how the sensor generates timestamp information.\n\n internalosc - Timestamps are generated from an internal oscillator. This is the default setting. syncpulsein - Timing is synced to pulses on the SYNC_PULSE_IN input. ptp1588 - Timing is synced to an external PTP master.\n\n pulseinpolarity - - The polarity of the SYNC_PULSE_IN signal to use.\n\n activelow - activehigh -\n\n iomode - - Determines how the sensor uses the SYNC_PULSE_OUT signal.\n\n off - The signal is not used. This is the default setting. inputnmea - The sensor will expect standard NMEA $GPRMC UART messages on the multipurpose IO port. See here for more information on GPS NMEA data. outputinternalosc - Signal output is taken from the internal oscillator. outputsyncpulsein - outputptp1588 - outputangle - Signal output is based on the angle of the encoder.\n\n pulseoutpolarity - - Polarity of the output signal pulse.\n\n activelow - activehigh -\n\n pulseoutfrequency - Frequency of the output pulse in Hz (must be greater than 0).\n\n\n\n pulseoutangle - The encoder angle at which to output a signal pulse. Measured in degrees less than 360.\n\n\n\n pulseoutwidth - Width of the output signal pulse in mm.\n\n\n\n nmeainpolarity - - Sets the polarity of the NMEA URT input $GPRMC messages. Set to 'Active High' if UART is active high, idle low, and the start bit is after a falling edge.\n\n activelow - activehigh -\n\n nmeaignorevalidchar - Turn off, if the NMEA UART input $GPRMC messages should be ignored if valid character is not set, and turn on if messages should be used for time syncing regardless of the valid character.\n\n\n\n nmeabaudrate - - The baud rate for the incoming NMEA URT input $GPRMC messages.\n\n baud9600 - baud115200 -\n\n nmealeapseconds - An integer number of leap seconds that will be added to the UDP timestamp when calculating seconds since 00:00:00 Thursday, 1 Jan 1970. Set to 0 for Unix Epoch Time.\n\n\n\n\n\n autostart - Tell the sensor to automatically begin sending data when it turns on. The default is On.\n\n\n\n\n\n outputresolution - - quickly change the resolution of the 's data.\n\n useinput - Uses the input's resolution. eighth - Multiply the input's resolution by that amount. quarter - Multiply the input's resolution by that amount. half - Multiply the input's resolution by that amount. 2x - Multiply the input's resolution by that amount. 4x - Multiply the input's resolution by that amount. 8x - Multiply the input's resolution by that amount. fit - Grow or shrink the input resolution to fit this resolution, while keeping the aspect ratio the same. limit - Limit the input resolution to be not larger than this resolution, while keeping the aspect ratio the same. custom - Directly control the width and height.\n\n resolution - - Enabled only when the parameter is set to Custom . Some Generators like Constant and Ramp do not use inputs and only use this field to determine their size. The drop down menu on the right provides some commonly used resolutions.\n\n resolutionw - resolutionh -\n\n resmenu - A drop-down menu with some commonly used resolutions.\n\n\n\n resmult - Uses the Global Multiplier found in Edit>Preferences>TOPs. This multiplies all the TOPs resolutions by the set amount. This is handy when working on computers with different hardware specifications. If a project is designed on a desktop workstation with lots of graphics memory, a user on a laptop with only 64MB VRAM can set the Global Multiplier to a value of half or quarter so it runs at an acceptable speed. By checking this checkbox on, this is affected by the global multiplier.\n\n\n\n outputaspect - - Sets the image aspect ratio allowing any textures to be viewed in any size. Watch for unexpected results when compositing TOPs with different aspect ratios. (You can define images with non-square pixels using xres, yres, aspectx, aspecty where xres/yres != aspectx/aspecty.)\n\n useinput - Uses the input's aspect ratio. resolution - Uses the aspect of the image's defined resolution (ie 512x256 would be 2:1), whereby each pixel is square. custom - Lets you explicitly define a custom aspect ratio in the Aspect parameter below.\n\n aspect - - Use when Output Aspect parameter is set to Custom Aspect.\n\n aspect1 - aspect2 -\n\n armenu - A drop-down menu with some commonly used aspect ratios.\n\n\n\n inputfiltertype - - This controls pixel filtering on the input image of the .\n\n nearest - Uses nearest pixel or accurate image representation. Images will look jaggy when viewing at any zoom level other than Native . linear - Uses linear filtering between pixels. This is how you get images in viewers to look good at various zoom levels, especially useful when using any Fill Viewer setting other than Native . mipmap - Uses mipmap filtering when scaling images. This can be used to reduce artifacts and sparkling in moving/scaling images that have lots of detail.\n\n fillmode - - Determine how the image is displayed in the viewer.\nNOTE:To get an understanding of how TOPs work with images, you will want to set this to Native as you lay down TOPs when starting out. This will let you see what is actually happening without any automatic viewer resizing.\n\n\n useinput - Uses the same Fill Viewer settings as it's input. fill - Stretches the image to fit the edges of the viewer. width - Stretches image to fit viewer horizontally. height - Stretches image to fit viewer vertically. best - Stretches or squashes image so no part of image is cropped. outside - Stretches or squashes image so image fills viewer while constraining it's proportions. This often leads to part of image getting cropped by viewer. nativeres - Displays the native resolution of the image in the viewer.\n\n filtertype - - This controls pixel filtering in the viewers.\n\n nearest - Uses nearest pixel or accurate image representation. Images will look jaggy when viewing at any zoom level other than Native . linear - Uses linear filtering between pixels. Use this to get images in viewers to look good at various zoom levels, especially useful when using any Fill Viewer setting other than Native . mipmap - Uses mipmap filtering when scaling images. This can be used to reduce artifacts and sparkling in moving/scaling images that have lots of detail. When the input is 32-bit float format, only nearest filtering will be used (regardless of what is selected).\n\n npasses - Duplicates the operation of the the specified number of times. For every pass after the first it takes the result of the previous pass and replaces the node's first input with the result of the previous pass. One exception to this is the GLSL TOP when using compute shaders, where the input will continue to be the connected 's image.\n\n\n\n chanmask - Allows you to choose which channels (R, G, B, or A) the will operate on. All channels are selected by default.\n\n\n\n format - - Format used to store data for each channel in the image (ie. R, G, B, and A). Refer to Pixel Formats for more information.\n\n useinput - Uses the input's pixel format. rgba8fixed - Uses 8-bit integer values for each channel. srgba8fixed - Uses 8-bit integer values for each channel and stores color in sRGB colorspace. Note that this does not apply an sRGB curve to the pixel values, it only stores them using an sRGB curve. This means more data is used for the darker values and less for the brighter values. When the values are read downstream they will be converted back to linear. For more information refer to sRGB. rgba16float - Uses 16-bits per color channel, 64-bits per pixel. rgba32float - Uses 32-bits per color channel, 128-bits per pixels. rgb10a2fixed - Uses 10-bits per color channel and 2-bits for alpha, 32-bits total per pixel. rgba16fixed - Uses 16-bits per color channel, 64-bits total per pixel. rgba11float - A RGB floating point format that has 11 bits for the Red and Green channels, and 10-bits for the Blue , 32-bits total per pixel (therefore the same memory usage as 8-bit RGBA).

"description": "NOTE\n\nLicense: Only available in TouchDesigner Educational, TouchDesigner Commercial and TouchDesigner Pro.\n\n\n\nOuster makes LIDAR devices for scanning 3D environments. The Ouster TOP sends and receives data with an Ouster Imaging Lidar, converting to point cloud data on the . For more information see the user guides at Ouster.io\nRequirements:\n\nThe currently supports Ouster devices using version 2.x firmware. Devices that require version 3 firmware are not currently supported.\nAccess to your local network to connect with the sensor device. Check your firewall settings if you have trouble accessing the device.\nHigh resolution scanning modes require up to 130Mbps of bandwidth. Gigabit Ethernet hardware is required for full operation. Insufficient bandwidth will cause broken images and missing frames.Features include:\n\nAdditional sensor data like IMU (Inertial Measurement Unit - the gyroscope and accelerometer), packet counts, matrices via Info and Info .\nVisual Panoramic and Scan Order capture formats selectable in 'Image ' parameter.\nFlexible X, Y, Z, Range, Intensity and Noise plane mapping to RGBA Image Channels\nTime Sync Mode for supporting multiple devices in the same area (Internal OSC, Sync In, PTP 1588)\nAuto startup featuresConnection Instructions:\nTo connect to the sensor, you will need either the IP addressed assigned by the local DHCP server or the name of the device. The name is based on the serial number that is usually printed on the top of the sensor in the format \"os-############\". This name can be entered directly into the Device Address parameter (see parameter help below). You can also connect to the device through a web browser using the IP or name in the format http://os-###########/. The web interface allows you to check the status of the device and gives additional error information.\nOnce the device is configured, it will continue to send output to the target IP address so it is not required to enter the device address again unless you need to change the configuration.\nRange data collected from the device is presented as 32bit floating point values in the RGBA channels of the output image. Output can be arranged either in chronological scan order or as a panoramic image using the Image parameter. IMU data from the device can be accessed by connecting an Info CHOP. If more than 4 output channels are needed, you can use a Ouster Select TOP to create additional output images.\nNote: All 3D coordinates are transformed into TouchDesigner space where Y is up and X and Z represent the ground plane. This is different from the original coordinate space defined in the Ouster documentation.\nThe lookup tables used to convert the range values into 3D points can be accessed with an Info DAT.\nSee also: Ouster Select TOP\nousterTOP_Class\n\nContents\n \n \n \n \n \n \n \n \n \n \n\n\n\n\n\n active - Enables connections with the device.\n\n\n\n deviceaddress - The IP address or the name of the Ouster device. The address is only required during configuraton. The device will request an address from the local DHCP server when it is connected to the network. The name of the device is printed on the top of the sensor in the format \"os-#####\", where ##### is the serial number e.g. \"os-991900123456\". You can determine the IP address using the ping command and the device name e.g. ping -4 os-991900123456. For more information see the Ouster User Guide at Ouster.io.\n\n\n\n lidarport - The UDP port number to receive lidar data.\n\n\n\n imuport - The UDP port number to receive data from the inertial measurement unit (IMU) on the device.

If the address is left blank, the default network address will be used.\n\n\n\n scanmode - - Select a scanning mode to set the sensor's horizontal resolution and number of revolutions per second. The vertical resolution is determined by the hardware e.g. an OS1-64 sensor has vertical resolution of 64 pixels (samples).\n\n mode512x10 - mode512x20 - mode1024x10 - mode1024x20 - mode2048x10 -\n\n configdevice - Enable this toggle to have the Ouster set the configuration properties of the device. If the device has already been configured to the correct mode and network connections than this can be disabled to save some processing time.\n\n\n\n\n\nThe Output page allows you to select what data is placed in the 's output image. Range, Intensity, Reflectivity and Noise are raw data channels coming from the sensor, while XYZ position values are calculated by using the range data and the look up table of beam azimuth and altitude angles. Range is measured in millimeters, while XYZ positions are in meters. If you need more than 4 channels of data, use a Ouster Select TOP to create a second output image from the same sensor data.\nIn addition to the sensor data, you can also assign a constant value of one or zero to a channel by selecting the corresponding entry from the menu. Selecting 'Active Mask' from the channel menu will output a one if the pixel represents valid sensor data or a zero if it is padding (when the image contains more pixels than there is available sensor data).

One exception to this is the GLSL TOP when using compute shaders, where the input will continue to be the connected 's image.\n\n\n\n chanmask - Allows you to choose which channels (R, G, B, or A) the will operate on. All channels are selected by default.\n\n\n\n format - - Format used to store data for each channel in the image (ie. R, G, B, and A). Refer to Pixel Formats for more information.\n\n useinput - Uses the input's pixel format. rgba8fixed - Uses 8-bit integer values for each channel. srgba8fixed - Uses 8-bit integer values for each channel and stores color in sRGB colorspace. Note that this does not apply an sRGB curve to the pixel values, it only stores them using an sRGB curve. This means more data is used for the darker values and less for the brighter values. When the values are read downstream they will be converted back to linear. For more information refer to sRGB. rgba16float - Uses 16-bits per color channel, 64-bits per pixel. rgba32float - Uses 32-bits per color channel, 128-bits per pixels. rgb10a2fixed - Uses 10-bits per color channel and 2-bits for alpha, 32-bits total per pixel. rgba16fixed - Uses 16-bits per color channel, 64-bits total per pixel. rgba11float - A RGB floating point format that has 11 bits for the Red and Green channels, and 10-bits for the Blue , 32-bits total per pixel (therefore the same memory usage as 8-bit RGBA). The Alpha channel in this format will always be 1. Values can go above one, but can't be negative. ie. the range is [0, infinite). rgb16float - rgb32float - mono8fixed - Single channel, where RGB will all have the same value, and Alpha will be 1.0. 8-bits per pixel. mono16fixed - Single channel, where RGB will all have the same value, and Alpha will be 1.0. 16-bits per pixel. mono16float - Single channel, where RGB will all have the same value, and Alpha will be 1.0. 16-bits per pixel. mono32float - Single channel, where RGB will all have the same value, and Alpha will be 1.0. 32-bits per pixel. rg8fixed - A 2 channel format, R and G have values, while B is 0 always and Alpha is 1.0. 8-bits per channel, 16-bits total per pixel. rg16fixed - A 2 channel format, R and G have values, while B is 0 always and Alpha is 1.0. 16-bits per channel, 32-bits total per pixel. rg16float - A 2 channel format, R and G have values, while B is 0 always and Alpha is 1.0. 16-bits per channel, 32-bits total per pixel. rg32float - A 2 channel format, R and G have values, while B is 0 always and Alpha is 1.0. 32-bits per channel, 64-bits total per pixel. a8fixed - An Alpha only format that has 8-bits per channel, 8-bits per pixel. a16fixed - An Alpha only format that has 16-bits per channel, 16-bits per pixel. a16float - An Alpha only format that has 16-bits per channel, 16-bits per pixel. a32float - An Alpha only format that has 32-bits per channel, 32-bits per pixel. monoalpha8fixed - A 2 channel format, one value for RGB and one value for Alpha. 8-bits per channel, 16-bits per pixel. monoalpha16fixed - A 2 channel format, one value for RGB and one value for Alpha. 16-bits per channel, 32-bits per pixel. monoalpha16float - A 2 channel format, one value for RGB and one value for Alpha. 16-bits per channel, 32-bits per pixel. monoalpha32float - A 2 channel format, one value for RGB and one value for Alpha. 32-bits per channel, 64-bits per pixel.\n\n\n\nExtra Information for the Ouster can be accessed via an Info CHOP.\n\n\n - The number of lidar packets received by the .

This is the high-speed, many-core processor of the graphics card/chip that takes geometry, images and data from the CPU and creates images and processed data.\n\n\n\nAn Operator Family that creates, composites and modifies images, and reads/writes images and movies to/from files and the network. TOPs run on the graphics card's GPU.\n\n\n\nAn Operator Family which operate on Channels (a sequence of numbers (Samples)) which are used for animation, audio, mathematics, simulation, logic, UI construction, and data streamed from/to devices and protocols.\n\n\n\nAn Operator Family that manipulates text strings: multi-line text or tables. Multi-line text is often a python Script or GLSL Shader, but can be any multi-line text. Tables are rows and columns of cells, each containing a text string.\n\n\n\n(1) The TouchDesigner window is made of a menu bar at the top, a Timeline at the bottom, plus one of a choice of Layouts in the middle. A Layout is made on one or more Panes, each Pane can contain a Network Editor, Viewer, Panel, etc. See Pane and Bookmark. (2) Nodes in a network are arranged using Layout commands in the RMB menu.\n\n\n\nTo \"pulse\" a parameter is to send it a signal from (1) an exported CHOP channel or (2) a python command or (3) a mouse click that causes a new action to occur immediately. A pulse via python is via the .pulse() function on a pulse-type parameter, such as Reset parameter in a Speed CHOP. A pulse from a CHOP is typically a 0 to 1 to 0 signal in an exported channel.\n\n\n\nThe width and height of an image in pixels. Most TOPs, like the Movie File In TOP can set the image resolution. See Aspect Ratio for the width/height ratio of an image, taking into account non-square pixels.\n\n\n\nThe viewer of a node can be (1) the interior of a node (the Node Viewer), (2) a floating window (RMB->View... on node), or (3) a Pane that graphically shows the results of an operator.\n\n\n\nA CHOP outputs one or more channels, where a channel is simply a sequence of numbers (Samples), representing motion, audio, etc. Channels are passed between CHOPs in TouchDesigner networks. Channels can be Exported to Parameters.\n\n\n\n\n\n\n\n\nRetrieved from \"https://docs.derivative.ca/index.php?title=Ouster_TOP&oldid=29672\"",
