Details

Animations can be created in a loop modifying the scene and saving a screenshot to a file. (See example below)

This function is a wrapper for the GL2PS library by Christophe Geuzaine, and has the same limitations as that library: not all OpenGL features are supported, and some are only supported in some formats. See the reference for full details.
