c1ce6c90ca Moved gl_dynlight to hwrenderer because it does not depend on any direct renderer info. 2018-04-16 09:02:48 +02:00

3e6f69f64a Renamed two functions 2018-04-16 08:55:13 +02:00

8a2e52d651 Removed gl_lights_checkside which essentially was just a pointless piece of cruft inherited from ZDoomGL. 2018-04-16 08:45:50 +02:00

f57c804a5a store shadow map index in the light actor instead of a separate TMap 
This frees another file of a direct renderer dependency and generally also should be faster

60aebff4a1 - starting separation of hardware dependent and hardware independent code, starting with aabbtree, because it was easy. 2018-04-02 15:58:28 +02:00

248a29bf06 - resorted portal render data. 
Compiles but does not work...

3b024c347b - use a dedicated flag word for the dynamic light flags instead of piggybacking on some flags4 bits. 2017-06-18 10:15:31 +02:00

fee18a6971 - fixed the attenuation check in gl_GetLight. 2017-03-17 20:16:49 +01:00

4cd0d3d454 - removed the Vector class in the GL renderer and replaced all its uses with FVector3. 
- optimized the math to get a plane equation from a linedef. The original code used a generic algorithm that knew nothing about the fact that Doom walls are always perfectly vertical. With this knowledge the plane calculation can be reduced to a lot less code because retrieving the normal is trivial in this special case.
- use the SSE2 rsqrtss instruction to calculate a wall's length, because this is by far the most frequent use of square roots in the GL renderer. So far this is only active on x64, it may be activated on 32 bit later as well, but only after it has been decided if 32 bit builds should be x87 or SSE2.

ef3421eee5 - moved dynamic lights out of the GL code into the common game code. 
Since the true color software renderer also handles them there is no point keeping them on the GL side.
This also optimized how they are stored, because we no longer need to be aware of a base engine which doesn't have them.

bea625a42c - added an ATTENUATE flag to dynamic lights, this is set by default for attached lights. For placed lights this is off, because it'd interfere with many existing maps that depend on unattenuated lights. 2016-10-23 20:42:48 +02:00

8b6e09ca09 - changed the license of the OpenGL renderer to LGPL v3. 
This was done to clean up the license and to ensure that any commercial fork of the engine has to obey the far stricter requirements concerning source distribution. The old license was compatible with GPLv2 whereas combining GPLv2 and LGPLv3 force a license upgrade to GPLv3. The license of code that originates from ZDoomGL has not been changed.

8b01a88b76 - removed gl_lights_size and gl_lights_intensity. 
Both of these were inherited from ZDoomGL and in terms of light design in maps it makes absolutely no sense to have them user configurable. They should have been removed 11 years ago.

e7856ce1e3 - removed unused forceadditive parameter from gl_GetLight. 
- restricted gl_lights_additive to legacy code and removed menu entry for this.

For modern hardware this setting is completely pointless, it offers no advantage and degrades visual quality. Its only reason for existence was that drawing additive lights with textures is a lot faster, and that's all it's being used for now.

365c192a1d - added portal support for dynamic lights. 
This requires fixed offsets so it only works with linked portals.

5816049510 - made necessary adjustments for the coordinate refactoring in ZDoom. 2016-01-21 12:36:37 +01:00

b8bcbe819b - removed texture based dynamic lighting. For GL 3.x the shader approach is always better. 
- fixed: sky fog was not unset.

2925c96b59 removed all GL 2.x code. 
After thinking about it for a day or so I believe it's the best option to remove all compatibility code because it's a major obstacle for a transition to a core profile.

c47c7421a3 - route all glColor calls through render state. 
- add sector links to dynamic lights.
 2014-05-11 22:57:42 +02:00

978ace241c - removed all code that mixes together the different lighting methods. Now everything goes through the 3 different light parameters in the render state. 
- removed cm parameter from many functions.

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
Christoph Oelckers
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
