I meant Rendering Software. The idea is to enhance rendering capabilities of standard P3D processing rendering mode, communicating processing on real time with another external software (such as maya, keyshot, vray, maxwell,,)
I don't think that is possible without any external libraries, or even with them. Processing renders all graphics using OpenGL (atleast as far as P2D and P3D are concerned).

What exactly do you mean by "rendering engine"?

You thinking using Syphon / Spout and piping Processing rendering into something else for some purpose?
I don't really think that will speed up the program in any way... It might even slow it down.
