d84e079282 - render partial sprites oon the back side of a portal for actors in front of it. This is needed because the stencil will clip away those parts. 2016-04-30 16:57:53 +02:00
Christoph Oelckers
21283b18f4 - preparations for using clip planes on line portals. 2016-04-29 01:48:06 +02:00

066d5c63e2 - better be safe and not call GL_CLIP_DISTANCE functions on old hardware. 2016-04-26 21:55:17 +02:00
Christoph Oelckers
6e1b21d513 - added back sprite splitting for low end, plus some dynamic light code. 2016-04-26 21:31:24 +02:00
Christoph Oelckers
6450752399 - made it compile again. 
The software renderer float conversion removed viewx and viewy which are still needed for efficient position checks against nodes without constant float->fixed conversions.

4af859094c - fixed: sprite clipping did not work anymore because the 'invalid' value was inconsistent. 
- cleaned up the 'if' condition in PerformSpriteClipAdjustment,
- enabled weapon bobbing interpolation.

a27181cb0b - partial adjustments. 
No point changing all the viewx/y/z stuff when that is about to get floatified next.

ae1571158c - fixed: The portal link table was not created when there were no sector portals. 
- fixed: P_TryMove could loop endlessly over a list of static portals when there was an error during portal creation.

e3ddc74eb1 - check r_showviewer when deciding whether to render the player sprite. This is necessary when camera and player end up on different sides of a portal. 2016-02-24 01:14:24 +01:00
Christoph Oelckers
bd9907f20f - missing #includes in GL code. 2016-02-16 22:06:26 +01:00
Christoph Oelckers
0931134a9c - fixed: part of the special handling of projectiles being spawned near the camera also affected other actors, this caused the fly cheat to break. 2016-02-12 11:20:33 +01:00

dda73b531c Merge branch 'master' of https://github.com/rheit/zdoom 
# Conflicts:

This only updates to a compileable state. The new portals are not yet functional in the hardware renderer because they require some refactoring in the data management first.

faa08410de - handle nocoloredspritelighting with 3D light splitter 2016-02-01 19:10:15 +01:00
Christoph Oelckers
2c55dcca27 - use hardware clipping to apply 3D lights to sprites. This solves all the problems with properly lighting models and billboarded sprites. 
- add some restrictions for the checks that exclude sprites which are too close to the camera. Most importantly, for clipping the first frame of a projectile, do not solely clip against the projectile's speed but use the player's radius as a limiting factor to avoid too large distances.

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

ffa069205f - fixed: For fullbright sprites, a weapon's extra light must be ignored because it can be negative. 2014-12-25 18:30:34 +01:00
Christoph Oelckers
3c7664a460 - we don't really need a bBrightmap in a texture. All it did was duplicate some functionality of bMasked. 
- renamed bBrightmapDisablesFullbright flag.
 2014-10-26 08:41:52 +01:00
Christoph Oelckers
066e53ae4c - fixed: sprites rendered as 'bright' should not be affected by dynamic lights. 2014-10-23 10:54:26 +02:00
Christoph Oelckers
a25ed3c807 - fixed: inverted rendering for fuzzy things with light powerup was switched off due to change of render style. 2014-09-15 12:15:19 +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
Christoph Oelckers
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.

ece10bb57f - fixed several incorrect uses of abs instead of fabs. 2014-07-27 21:57:05 +02:00
Christoph Oelckers
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.
 2014-07-15 21:16:59 +02:00
Christoph Oelckers
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
Christoph Oelckers
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.

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
5b302ed3a6 - added benchmarking calls for glDrawArrays to see how well issunig draw calls performs on different hardware. 2014-06-14 15:16:33 +02:00

4d005bdfa0 shader rework 
All those special shaders have been merged together.
Mostly working but the non-shader lighting seems a bit broken.

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

b9a6fe80a4 Do not use the shader to handle STYLEF_RedIsAlpha. 
Turns out that the name doesn't accurately describe what it does.
It is correct for images that come with their own palette or are true color.
But for images using the game palette it doesn't use the red channel to determine translucency but the palette index! Ugh...

This means it cannot be done with a simple operation in the shader because it won't get a proper source image. The only solution is to create a separate texture.

c47c7421a3 - route all glColor calls through render state. 
- add sector links to dynamic lights.
 2014-05-11 22:57:42 +02:00
Christoph Oelckers
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.
 2014-05-11 21:47:54 +02:00

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.
 2014-05-11 17:56:38 +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
Christoph Oelckers
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.
 2014-04-06 14:35:44 +02:00

d46315c44b - some finetuning of subtractive effect. 2013-12-05 15:39:46 +01:00
Christoph Oelckers
95163e378e - added a fog layer when drawing sprites with render style reverse subtract. 2013-12-05 15:06:10 +01:00
Christoph Oelckers
12985cf635 - fixed: Particle drawing needs to apply the current fixed colormap to the particle's color. 2013-11-30 12:35:38 +01:00
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
62fd6c8e74 - fixed: light values read from 3D floor light lists for lighting sprites were not clamped to [0..255]. 2013-08-09 23:12:21 +02:00
Christoph Oelckers
399d0974ab - added GL render as of SVN revision 1600. 2013-06-23 09:49:34 +02:00
