Detailed Description

An object which renders geometry to a vertex.

Remarks: This is especially useful together with geometry shaders, as you can render procedural geometry which will get saved to a vertex buffer for reuse later, without regenerating it again. You can also create shaders that run on previous results of those shaders, creating stateful shaders.
