887d35d559 - remove colormap from texture generation parameters. The one remaining special case, alpha texture on old hardware is now handled by the currently set texture mode at the time of use. 
- use the cleaned up decal lighting code from the first GLEW branch.

7793bbbcc9 Further cleanup of lighting code. 
- remove thing color from lighting calculations.
- implement alpha textures and inverse sprites for infrared as texture modes. This still requires some handling for the alpha texture mode for non-shader rendering because there is no way in the fixed pipeline to do it. The inverted texture effect can be done with a texture combiner.
- fixed: ThingColor for sprites was set in the wrong place. It must be in the Process function, not in the lighting calculation.
- added functions for isolated calculation of sprites' dynlight color.

52056a05bd - changed handling of DynLight in shader to serve as a global dynamic light color for all lighting modes. 2014-05-11 16:49:17 +02:00

53f4cd0108 - added objectcolor uniform. This will be used to hold the thingcolor for shader based rendering. 2014-05-11 16:06:25 +02:00

f3a9cb0cfa remove special texture creation for fullscreen colormaps. 
On GL 3.x+ this isn't needed at all and on older hardware it causes performance issues, in particular with hires textures due to impossibility of precaching.
In addition it forces some really awkward handling of lighting for things that have their own color, like stenciled sprites or particles.

With this special case gone it will be possible to handle this case in a saner manner than it is right now.

As compensation for older hardware a fullscreen blend will be drawn over the entire screen. This won't be 100% accurate but it's preferable to keeping the current method.

cd6d653b59 - fixed: the delayed state changer for the alpha function called glBlendFunc instead of glAlphaFunc. 2014-05-11 13:29:06 +02:00

09f4071436 Ok, it had to be done: Removed shader support for pre GLSL 1.3/GL 3.0 hardware. The compromises needed to accomodate these are just too bad and would block any attempt at streamlining the code. 2014-05-11 13:27:51 +02:00

a42cde0837 - removed #include of glxew.h because it's not used. 
- removed some unused functions from gl_interface.cpp which were causing problems when compiling on Linux.

f7404d20fb - add vertex buffer based drawing for all walls and flats. 2014-05-11 01:23:27 +02:00
Christoph Oelckers
7d3beb665b - rewrote vertex buffer code to require GL_ARB_BUFFER_STORAGE extension. 
This means it won't work anymore on anything that doesn't support OpenGL 4.0, but I don't think this is a problem. On older NVidia cards performance gains could not be seen and on older AMDs using the vertex buffer was even worse as long as it got mixed with immediate mode rendering.

b09405a8bd - changed rendering of glowing walls so that it doesn't require an additional vertex attribute, just pass the floor and ceiling planes as uniforms. 2014-05-10 17:09:43 +02:00

1d4ea9f162 - removed the __asm nop breakpoints for debugging. They not only do not work on non-MSVC but also not on 64 bit. 2014-05-08 09:48:39 +02:00
Christoph Oelckers
314225f1b0 - don't depend on stdint.h because older MSVC versions do not have it. 2014-05-01 12:30:56 +02:00

94b06900cb - got rid of a lot of stuff that's no longer required with GLEW. 
- replaced GLUs texture scaling with our own function. This is only used to scale down textures larger than what the hardware can handle so we do not need a dependency to an essentially deprecated library for it.

69af73d9b9 - alternative configuration using GLEW to get extension functions. This requires GL 2.0, though so it won't be promoted to the mainline for the time being. 
- removed all pre GL 2.0 support.

47406a3406 - I don't think it's a good idea to put a 64 MB lookup table into the static data segment, if it's for a piece of code most people will never use... 2014-04-03 23:02:43 +02:00

d48d337883 convert file from UTF-16LE to UTF-8 
This one file gave issues with parsing in certain programs, including
the GitHub UI. No need for English text to waste so much space.

058f065446 - fixed: FFlatVertex contained two unused members. 
- fixed: Clearing the args in the VavoomLightColor constructor only cleared 5 bytes, still assuming byte args.

ac0c07a51b - fixed: Since model skins are managed by the texture manager, the model code may not delete them itself. 2013-10-11 12:57:46 +02:00
Christoph Oelckers
0f8ed0123f - fixed: Models must not delete their skin textures because they are stored in the texture manager which will be responsible for doing this. 2013-10-11 01:04:54 +02:00

5f08111a34 - fixed: The GL voxel palette loader needs to handle the case when the voxel has no own palette and used the game's base palette instead. Also added an implementation for GetPixels because this is used when a voxel needs a translated palette. 2013-09-28 23:33:55 +02:00

0ff21c3af7 - fixed: Sprites may never be used as a base of a texture redirect 
Due to autoexpansion to remove filtering artifacts their dimensions are not the same as for patches. But if the sprite hadn't been used yet this information won't have been set yet.

4dc06cca70 - changed minimum required GL version to 1.3. The only 1.4 feature that's required is mipmap generation which on many older cards is available as an extension. The worst thing that can happen with relaxing the version requirement is that on a few ancient graphics cards the mipmapped texture filtering modes produce garbage. 2013-09-02 08:43:56 +02:00
