4eb5f10b02 - use normals to have proper light attenuation. So far only implemented for walls and flats. Models are planned but need some thinking about how to efficiently collect all required lights for an object. 2016-10-03 16:09:32 +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.

aece9aaa58 - added xBRZ texture scaler after clearing the licensing conditions. A screenshot of the confirmation that this is ok has been added to the 'licenses' folder. 2016-09-03 14:01:51 +02:00

589936f570 - draw the colormap blend after postprocessing, not before it. 
- added colormap shader to postprocessing.

This replaces the in-place application of fullscreen colormaps if renderbuffers are active. This way the fully composed scene gets inverted, not each element on its own which is highly problematic for additively blended things.

3389a5a74e - removed most of the specific options for legacy hardware and consolidated them in one variable (does not work yet.) 2016-09-01 11:52:52 +02:00

0f0dc2c852 - implemented buffers for GL 3.x. These only get mapped during the data collection pass so the order of some things is different here. 2016-08-29 10:43:03 +02:00

250be72939 - added handling for drawing with uniform vertices. It draws something but in the wrong place. Right now I have no idea what's happening... 2016-08-22 15:31:23 +02:00
Christoph Oelckers
7ba5acfb35 - added quad drawer interface so that this part can be done without altering a vertex buffer. 
So far it's only the framework, the new code is not active yet.

675822004d - use static buffer data and a uniform to handle the texture positioning of the present shader. 
That's again one less write access to the buffer. The uniform method was chosen because this way a buffer update can be completely avoided, and setting a single uniform is a lot cheaper and simpler to handle.

9c9edbffdb - on older ATI drivers where the clip planes are broken, only disable the clip planes themselves, but not OpenGL 3.x so that dynamic lights still work as intended. 
- only disable clip planes on Windows, but not on Linux or macOS.
- If a driver reports full OpenGL 4.5 support, assume that all features are working properly.

47064e24c9 - only bind the uniform buffer if it is actually going to be used. No need to check if we are use a shader storage buffer. 2016-05-01 12:01:44 +02:00

21283b18f4 - preparations for using clip planes on line portals. 2016-04-29 01:48:06 +02:00
Christoph Oelckers
09f54b0940 - cleaned up the clip plane management for portals. 
Unfortunately the math behind the old clip planes is utterly impenetrable and so poorly documented that I have no idea how to set that up, so it is deactivated for now. It wasn't working anyway.
