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

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

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

6b038a5dae - fixed: GLPortal::DrawPortalStencil must apply the render state before drawing anything. 2014-06-15 10:30:03 +02:00

1b91a8f88c - removed old immediate mode path for generating stencils. 2014-06-15 10:15:44 +02:00

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

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

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.

2885056f46 - moved GLEXT API out of RenderContext struct. 2013-09-03 18:29:39 +02:00

26943fe3fd - removed gl interface function pointers for all OpenGL32.dll entry points. 2013-09-03 14:05:41 +02:00

737708b635 - fix c++11's compile problems. 2013-08-28 08:33:11 +02:00

b61ef3a107 - bumped minimum supported OpenGL version to 1.4. The engine was already using several 1.3 and 1.4 features which would have caused problems on 1.2.
- removed gl_vid_compatibility. With the bump to 1.4 no hardware requiring this flag is supported anymore.
- disabled 16 bit framebuffers for the same reason. As a conseqence all code for rendering without stencil could also be removed.
