754c96a540 - added default precision settings to shader include because some old ATI drivers complain if they aren't there - even though the spec doesn't require them... 2014-07-27 16:09:47 +02:00

a21f01bc5f - added jpalomo's submission to make freelook a 3-state setting, like crouch and jump. This required moving around the flags a bit so demo compatibility had to be bumped. It may also require adjustment for launchers that can set the dmflags. 2014-07-26 10:15:07 +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.

bd5bf2a40a - Expand environment variables for autoload paths. 
- Forgot to save the French translation file for the last commit, so a few more corrections there.

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

fc0cf4f998 - GZDoom now runs on an OpenGL core profile. :) 
It's probably still necessary to replace GLEW with another loader library. GLEW is pretty much broken on core OpenGL without some hacky workarounds...

00fcf4bc06 - for some reason using world coordinates for clipping in the shader is somewhat imprecise so the clip plane heights have to be adjusted a bit for it. 2014-07-13 13:25:42 +02:00

d868f60f6c - since the clip planes for plane mirrors did not work anymore I reimplemented them using shader based logic. It still needs to be seen if this affects performance on older hardware. 2014-07-13 12:14:12 +02:00

a936629cec - use default fragment shader for burn and stencil shader, with the time consuming parts disabled by a #define, to avoid code duplication. 2014-07-10 10:33:07 +02:00

f710518903 - use a uniform array to store vertex data to render dynamic stuff on GL 3.x hardware without the ARB_buffer_storage extension. 
Due to the way the engine works it needs to render a lot of small primitives with frequent state changes.
But due to the performance of buffer uploads it is impossible to upload each primitive's vertices to a buffer separately because buffer uploads nearly always stall the GPU.
On the other hand, in order to reduce the amount of buffer uploads all the necessary state changes would have to be saved in an array until they can finally be used. This method also imposed an unacceptable overhead.
Fortunately, uploading uniform arrays is very fast and doesn't cause GPU stalls, so now the engine puts the vertex data per primitive into a uniform array and uses a static vertex buffer to index the array in the vertex shader.
This method offers the same performance as immediate mode but only uses core profile features.

a3a7ee569f Multi-intermission waits for all players + changes 
- Added a segment of code that now makes the intermission wait for all
players before advancing, instead of continuing on any player. A "ready
icon" shows to reflect this.

- The Deathmatch intermisson couldn't show the ready icon (because it
just used the ingame scoreboard), so a proper intermission was added,
which reflects the same design as the coop scoreboard.

- The colour column wasted more space then it should have needed, so it
was replaced with player colour backgrounds.

- Slight y offset adjustments to make everything fit in 320x200
properly.

8f5683e23d - moved secret found message to string table and removed the CVAR crutch that dates from a time when modifying string table content wasn't as easy as it is now. 
- added 'showsecretsector' CVAR to show the sector number with the secret found message.

39775cc904 - mystery of desaturation shader solved: The old code passed '1-desaturation' to the shader, the new code 'desaturation', so for the 'mix' function to work its arguments must be swapped. 2014-05-21 15:25:25 +02:00
Christoph Oelckers
54425ee2ef - fixed: Desaturation factor was applied incorrectly. 
- Also fixed some very strange thing in the shader's desaturate function. For unknown reasons using the 'mix' function there did not work.
- fixed: The fog boundary special shader could not be used.

388f09f786 - fixed: In Heretic corpses do not get crunched to gibs, they just get their size reduced to 0. Handled by a new gameinfo flag. This also gets set for Chex quest which has the gib sprite replaced by something different. Using a Crush state will override this global flag. 2014-05-14 12:54:03 +02:00

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

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.
