"This version adds visualizers. Visualizers are a plugin based(I.e to create one you inherit the base visualizer class) and each surface has one.
A visualizer's job is to take and sync data, bind it's resources, then render.

Currently there is one visualizer, VL_VertexArray which as the name suggests adds vertex arrays to raptor, so you should see a big speed up from the last release.

The source is still engine/demo all in one, not separate yet. (I don't have a great ide so it's easier for me to keep it all in one atm)"

"Here's the first alpha of raptor 3d. It's a hybrid engine that is a port of MiniB3D by simon harris, and my own engine Trinity, both of which are open source PC GL engines. It's written against the latest svn version of PSPGL and as such requires you have it installed before using this. Currently the project is a single file containing a small demo and the engine, by alpha2 maybe 3, it will be organized into separate files for each class."
