CPlusPlus POP

Summary

The CPlusPlus POP allows you to make custom POP operators by writing your own plugin using C++.

See Write a CPlusPlus Plugin, Write a CPlusPlus POP and the other articles in the C++ Category for more detailed information on how to make plugins for use with this node and how to access example projects.

cplusplusPOP_Class

Parameters - CPlusPlus Page

Plugin Path plugin - The path to the plugin you want to load.

Re-Init Class reinit - ⊞ - When this parameter is On, it will delete the instance of the class created by the plugin, and create a new one.

• Re-Init Class reinit - When this parameter is On, it will delete the instance of the class created by the plugin, and create a new one.

• Re-Init Class reinitpulse - Instantly reinitialize the class.

Unload Plugin unloadplugin - When this parameter goes above 1, it will delete the instance of the class created by the plugin and unload the plugin. If multiple TOPs have loaded the same plugin they will all need to unload it to release the file.

Parameters - Common Page

Bypass bypass - Pass through the first input to the output unchanged.

Free Extra GPU Memory freeextragpumem - Free memory that has accumulated when output memory has grown and shrunk.

Delete Input Attributes delinputattrs - Only output which attributes you specify in this POP - helps isolate attributes into a separate branch.

Operator Inputs

• Input 0: -

Info CHOP Channels

Extra Information for the CPlusPlus POP can be accessed via an Info CHOP.

Common Operator Info Channels

• total_cooks - Number of times the operator has cooked since the process started.

• cook_time - Duration of the last cook in milliseconds.

• cook_frame - Frame number when this operator was last cooked relative to the component timeline.

• cook_abs_frame - Frame number when this operator was last cooked relative to the absolute time.

• cook_start_time - Time in milliseconds at which the operator started cooking in the frame it was cooked.

• cook_end_time - Time in milliseconds at which the operator finished cooking in the frame it was cooked.

• cooked_this_frame - 1 if operator was cooked this frame.

• warnings - Number of warnings in this operator if any.

• errors - Number of errors in this operator if any.

TouchDesigner Build: Latest\nwikieditor2025.30000

POPs (Point Operators) is a new  of TouchDesigner that runs on the GPU accelerated graphics card or chips, and creates/modifies 3D data which is rendered by the  or passed to devices like DMX lighting, LED arrays, lasers or other external systems.

The 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 . This path is displayed at the top of every , showing which Component's network you are currently in. To refer instead to a filesystem folder, directory, disk file or http: address, see .

An operator whose Bypass flag is set does nothing: All data going into its first input appears at its output unaffected.

The Graphics Processing Unit. 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.

Information associated with (or ) geometry. , and (polygons, lines, etc) can have any number of attributes. In POPs, position (P) is standard, and built-in optional attributes are (N), texture coordinates (Tex), color (Color), etc.

An which operate on (a sequence of numbers ()) which are used for animation, audio, mathematics, simulation, logic, UI construction, and data streamed from/to devices and protocols.
