Fixed compile error in debug build (thanks mont29)
Renamed some functions for consistency.
New features:
Create a Batch with immediate mode! Just use immBeginBatch instead of immBegin. You can keep the result and draw it as many times as you like. This partially replaces the need for display lists.
Copy a VertexFormat, and create a VertexBuffer using an existing format.
Resize a VertexBuffer to a different number of vertices. (can only resize BEFORE using it to draw)
Follow-up to rBddb1d5648dbd
API is nearly complete but untested.
1) create batch with vertex buffer & optional index buffer
2) choose shader program
3) draw!
This function modifies the GL program object, which reduces our ability to share a shader among meshes with different vertex formats. Recommended approach is to use get_attrib_locations.
Vertex Buffer to store vertex attribute data.
Element List (AKA Index Buffer) to select which vertices to use.
Batch combines these into an object that can be built once then drawn
many times.
Porting over from the C++ version… Most of this C code is compiled but
unused. Some of it is not even compiled. Committing now in case I’m
lost at sea.
Put Gawain source code in a subfolder to make the boundary between the
library and the rest of Blender clear.
Changed Gawain’s license from Apache to Mozilla Public License. Has
more essence of copyleft — closer to GPL but not as restrictive.
Split immediate.c into several files so parts can be reused (adding
more files soon…)
