The role of the Handle is to generate rotation values for the bones which will bring their attached handles as close to their respective targets as possible.\t\nThe use of this method is best described with an example:\t\t\n\nIncrease the frame range to 10000. Create a Null COMP called 'target' and animate a few random positions for it to travel to.\nCreate a three bone IK chain with No Kinematics. Append a Handle COMP to the last bone.\nIn the Handle set the Target menu to Target. This is the Null you just created.\nThe system is now specified. To actually start the IK enter a pane.\nPlace a Handle . In the Source field type in the names of the bones that were earlier created.\nClick the button on the Handle and click Play. You should now see the two-bone system chasing the animated null.Tip: In the geometry viewer, you can use the Select state to select the bones you created. Then in the Handle click the Grab Source Form Selection button. The names are entered automatically for you. You don't have to worry about being too picky when selecting objects this way, since non-bone objects are ignored.\t\t\nYou can place any number of bones with any number of (possibly zero) Handles attached to the system. The following parameter description will now give a more detailed explanation of the functionality:\nhandleCHOP_Class\n\nContents\n \n \n \n \n \n \n \n\n\n\n\n\n source - Creates rx/ry/rz channels for each bone listed.\n\n\n\t\n fixed - If you have entered bones which form a branch or should act as a unit, enter them here. An example may be two bones splitting at the shoulders. You want them to rotate, but only as a unit.\n\n\n\t\n iterations - Increasing this parameters gives a more accurate solution at the cost of cooking time. Preroll (only when precalculating a range of frames, SingleFrame turned off): This will cook the solution a given number of frames before the requested frame range. Max Angle Change: This will limit the delta angle degrees the bones can move in any given frame. Use this to tame erratic behavior.\n\n\n\t\n init - Specifies a frame in which the bones are reset to their default rest angles.\n\n\n\t\n preroll - Specifies the number of iterations to solve at the initialization frame.\n\n\n\t\n delta - Specifies the maximum change in degrees the solver is allowed to move each bone per frame. Use this parameter if the solution is too drastic.\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.\n\n\n\n srselect - - Handle cases where multiple input CHOPs' sample rates are different.

There are sixteen 3D Object Component and ten 2D Panel Component types. See also Network Path.\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\nThe term \"Frame\" is a measurement of time used (1) in the Timeline, (2) as a time-unit in CHOPs, and (3) as a time unit in movie files that are read into TOPs and written out from TOPs. The frame rate is the frames per second (FPS).\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\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\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\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.

The Network Path or Path for root is simply /.
