/*
|
||||
this is a "replacement" for vitaGL's immediate mode tailored specifically for xash
|
||||
this will only provide performance gains if vitaGL is built with DRAW_SPEEDHACK=1
|
||||
since that makes it assume that all vertex data pointers are GPU-mapped
|
||||
based on vglshim, as it has almost all needed for using glbegins on gles
|
||||
BufStorage mode should work similar to vglshim with vitagl's DRAW_SPEEDHACK
|
||||
as it uses gpu-mapped in similar way
|
||||
|
||||
gl2shim will not give much performance gain. It does not batch small drawcalls, just do little copy optimization
|
||||
It just allows to draw similar way as in native legacy context, but in es/core contexts
|
||||
|
||||
Limitations:
|
||||
1. Matrix support is very limited, only combined MVP
|
||||
2. No TexEnv support, multitexture always works in MODULATE mode
|
||||
3. DrawElements with client pointers will not work on CORE/WEBGL contexts, DrawRangeElements will
|
||||
4. No quads in arrays drawing (simple DrawArrays(GL_QUADS) may be implemented, but DrawElements not)
|
||||
5. Textures are enabled with texcoord attribs, not glEnable (can be changed, but who cares?)
|
||||
6. Begin/End limited to 8192 vertices. It is possible to support more, but need change glVertex logic to split drawcals, which may make it slower
|
||||
7. Textures internalformat ignored except of removing alpha from RGB textures
