53a389aafc - fixed: for untextured walls, the texture must be disabled before rendering.
- fixed: untextured walls should never be passed to SplitWall.
- fixed: untextured walls should not be affected by dynamic lights (it's either fog boundaries or outsides of 3D fog volumes.)

9ce6a7932c - implemented rendering of 3D lights with clip planes. 2016-01-31 22:04:20 +01:00

5448b335c6 - rewrote render loop for walls. Not working yet. 2016-01-31 21:10:59 +01:00

d037493ffe - fixed handling of FF_FADEWALLS on 3D floors. The problems with the old method became quite obvious in the demo map after the light list bug got fixed. 2016-01-29 17:13:14 +01:00

37ea94abf3 - fixed: translucent walls did not set up their dynamic lights in the GL4 render path. 2015-12-11 22:26:10 +01:00

4682736585 - fixed: non-tiled mid textures on a fog boundary require some special clamping to be performed in the shader. 2014-09-21 11:08:17 +02:00

43e2d704a3 - always use glPolygonOffset to render translucent geometry. 2014-09-20 09:04:36 +02:00

4bb320a27c - route texture binding through the renderstate class for better control. Currently it's just a direct passthrough but this will change. 2014-09-09 12:00:42 +02:00

12160bd29c - remove some obsolete code from decal rendering.
- avoid rebinding the same texture multiple times, as there's considerable overhead in the texture manager.
- check gl_sort_textures only once per scene, not per draw list.

1050013017 major cleanup of the texture manager:
- use sampler objects to avoid creating up to 4 different system textures for one game texture just because of different clamping settings.
- avoids flushing all textures for change of texture filter mode.
- separate sprite and regular dimensions on the material level to have better control over which one gets used. It's now an explicit parameter of ValidateTexture. The main reason for this change is better handling of wall sprites which may not be subjected to such handling.
- create mipmaps based on use case, not texture type.
- allows removal of FCloneTexture hack for proper sharing of the same sprite for decals and other purposes.
- better precaching of skyboxes.

00d7707aef - allow reallocation of light buffer if more lights are needed.
- added a light preprocessing pass to the renderer so that a non-persistent buffer can be used with minimal mapping/unmapping. This only gets used if necessary because it adds some overhead to the renderer.

b9ffb51d0c - small but important optimization: Two-sided lines with both sides in the same sector don't really require vertex splitting for precise rendering. 2014-08-04 23:00:40 +02:00

7967082e60 - use the light buffer to handle dynamic lighting. 2014-08-01 20:59:39 +02:00

eb9d2d9917 - reactivate compatibility profile so that immediate mode drawing can be used on older hardware not supporting persistently mapped buffers.
- reactivate alpha testing per fixed function pipeline
- use the 'modern' way to define clip planes (GL_CLIP_DISTANCE). This is far more portable than the old glClipPlane method and a lot more robust than checking this in the fragment shader.

6b9d6787d9 - move models into their own draw list to avoid frequent buffer changes.
- same for SKYHACK walls. Although rare, they would get in the way of optimizing the draw calls if not being separated out.

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

ed8a21fd86 - replaced deprecated alpha testing with shader code. 2014-07-14 21:14:43 +02:00

84a49e37ee - handle normals for spheremapped mirror surfaces using non-deprecated features.
- move all WGL references out of global header files so that global wgl header include is no longer necessary

9230a20f18 - added some checks to the wall rendering code that will allow to disable the clip planes in many cases, even when a plane mirror portal is active. This also solves the precision issue with using world coordinates for clip checks. 2014-07-13 17:15:17 +02:00

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.

e6f14b055a - use buffer based rendering for dynamic light pass and horizon portals. 2014-06-15 20:28:23 +02:00

1b91a8f88c - removed old immediate mode path for generating stencils. 2014-06-15 10:15:44 +02:00
Christoph Oelckers
3644073bbd - use a software buffer for immediate mode rendering. This allows using the regular buffer code to collect data for both render modes and allows removal of a lot of duplicated code. 2014-06-15 01:14:41 +02:00
Christoph Oelckers
c39318f406 - use vertex buffer and reuse of data for stencil drawing. A stencil needs to be drawn multiple times with the same polygons so this is a good place to optimize. 2014-05-31 09:32:17 +02:00
Christoph Oelckers
09ba62fbef - put all the common part of buffer based drawing into a separate method of the vertex buffer. 2014-05-20 22:37:38 +02:00

b514a815f4 - enable use of vertex buffer for sprite rendering. 2014-05-12 20:23:54 +02:00

98cc7eeb99 pass softlightlevel through render state. 2014-05-12 00:13:19 +02:00

506798f134 allow brightmaps and fullbright objects in fog. The reasons why they were disabled no longer exist. 2014-05-11 23:12:28 +02:00

c47c7421a3 - route all glColor calls through render state.
- add sector links to dynamic lights.

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
Christoph Oelckers
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

f7404d20fb - add vertex buffer based drawing for all walls and flats. 2014-05-11 01:23:27 +02:00
Christoph Oelckers
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
Christoph Oelckers
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
2885056f46 - moved GLEXT API out of RenderContext struct. 2013-09-03 18:29:39 +02:00
Christoph Oelckers
26943fe3fd - removed gl interface function pointers for all OpenGL32.dll entry points. 2013-09-03 14:05:41 +02:00
Christoph Oelckers
399d0974ab - added GL render as of SVN revision 1600. 2013-06-23 09:49:34 +02:00
