Only used when is turned on.\n\n\n\n\n\n timeslice - Turning this on forces the channels to be \"Time Sliced\". A is the time between the last cook frame and the current cook frame.\n\n\n\n scope - To determine which channels get affected, some CHOPs use a string on the Common page. See Pattern Matching.\n\n\n\n srselect - - Handle cases where multiple input CHOPs' sample rates are different. When Resampling occurs, the curves are interpolated according to the Interpolation Method Option, or \"Linear\" if the Interpolate Options are not available.\n\n first - Use rate of first input to resample others. max - Resample to the highest sample rate. min - Resample to the lowest sample rate. err - Doesn't accept conflicting sample rates.\n\n exportmethod - - This will determine how to connect the channel to the parameter. Refer to the Export article for more information.\n\n datindex - Uses the docked table and references the channel via the index of the channel in the . datname - Uses the docked table and references the channel via the name of the channel in the . autoname - The channel is the full destination of where to export to, such has geo1/transform1:tx.\n\n autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is : are relative to.\n\n\n\n exporttable - The used to hold the export information when using the Table Methods (See above).\n\n\n\n\n\n -\n\nExtra Information for the Trigger can be accessed via an Info CHOP.\n\n\n\n - Start of the interval in samples. - Number of samples in the . - The samplerate of the channels in frames per second. - Number of channels in the . - 1 if is enabled, 0 otherwise. - A count of how often the export connections have been updated.\n - Number of times the operator has cooked since the process started. - Duration of the last cook in milliseconds. - Frame number when this operator was last cooked relative to the component timeline. - Frame number when this operator was last cooked relative to the absolute time. - Time in milliseconds at which the operator started cooking in the frame it was cooked. - Time in milliseconds at which the operator finished cooking in the frame it was cooked. - 1 if operator was cooked this frame. - Number of warnings in this operator if any. - Number of errors in this operator if any.\nTouchDesigner Build: Latest\\nwikieditorwikieditorwikieditorwikieditorwikieditor2021.100002018.28070before 2018.28070\nCHOPs\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\nA Time Slice is the time from the last cook frame to the current cook frame. In CHOPs it is the set of short channels that contain the CHOP channels' samples between the last and the current cook frame.\n\n\n\nOP Snippets is a set of 700+ live examples of TouchDesigner operators. You can access snippets via the Help menu, or by right-clicking on network operators, or r-clicking on OP Create dialog items.\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\nsamples-per-second of a CHOP. Each CHOP in your network has a sample rate. In contrast, the overall timeline has a Frame Rate, which is the number of frames to cook and display per second, generally your monitor display frequency, default 60.\n\n\n\nA parameter in most CHOPs that restricts which channels of that CHOP will be affected. Normally all channels of a CHOP are affected by the operator. TOPs have Channel Mask, a similar feature.\n\n\n\nExporting is the connection of CHOP channels to parameters of operators. The output of each exporting CHOP is one or more channels, active only while the CHOP Viewer is on. The current value of a channel can be exported to a parameter of any operator, overriding that parameter's value. See Parameter.\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\nThe location of an operator within the TouchDesigner environment, for example, /geo1/circle1, a node called circle1 in a component called geo1. The path / is called Root. This path is displayed at the top of every Pane, showing which Component's network you are currently in. To refer instead to a filesystem folder, directory, disk file or http: address, see Folder.\n\n\n\nEvery operator in TouchDesigner has a set of control Parameters that can be integer or floating point numbers, menus, binary toggles, text strings or operator paths, which determine the output of the operator.\n\n\n\nTouchDesigner is a hierarchy of components. \"root\" is the top-most network in the hierarchy. The Network Path or Path for root is simply /. A typical path is /project1/moviein1.\n\n\n\n\n\n\n\n\nRetrieved from \"https://docs.derivative.ca/index.php?title=Trigger_CHOP&oldid=31078\"",
