- Software* + OpenGL support
- *Not supported: R_DrawColumnShadowed_8
- This has something to do with walls and FOF lights.
However, I don't see an easy code solution and I don't
know how to even test this.
- Ensures that column drawer doesn't read out of bounds
the brightmap column.
- Refactored code in r_segs.cpp, so it checks
R_TextureHasBrightmap.
- Added comments for plane brightmaps and sprite
brightmaps, that these are still error-prone.
- Cache DBGLINE texture
- Draw this texture at horizon (player's eye level)
- Draw this texture at max brightness
- Do not slope skew this texture
- Use R_DrawColumn_Flat_8 to colorize the this texture
Checks on a background thread since the complexity should
be O(n^2). The specific texture data it checks shouldn't
change after R_LoadTextures so it doesn't need a mutex.
All typedefs for structs that were present in other header
files have been moved to here. (Except node_t because the
renderer and netcode both define node_t LOL.)
All my work thus far on solving the drawflag/renderflag/additive/subtractive conundrum.
Outstandng problems:
* Bad additive/subtractive tables means that they appear opaque except under certain conditions.
* No support for FOFs, Polyobjects, or linedefs in OpenGL yet.
* All OpenGL support mostly done blind, may or may not function in practice.
If nothing else, the hard engineering problems are solved and it's just bug hammering...
