A simple C++ plugin showing how to plot screen-space trajectories/motion-trails via Maya Viewport 2.0 Render Override.
Make sure to set environment variable DEVKIT_LOCATION to the installed path before running CMake.
Once the plugin is built and loaded, you can access Simple Render Override in the "Renderer" drop-down menu on the 3-D viewport.
The plugin also provides a command simpleTrack to allow you to specify the selected object for tracking, as well as flags to modify the visuals:
- clear: remove all tracking objects.
- numOfFrames: number of frames before & after the current frame you wish to plot the trajectories.
- pointSize: size of the points of the trajectories.
- screenSpace: option to plot the trajectories in screen space (true) or world space (false).
