Christoph Oelckers	0aa0db637c	- started adding a SceneDrawer class to the OpenGL renderer. ... This will eventually hold all the global variables for the rendering.	2017-03-12 00:19:20 +01:00
Christoph Oelckers	d2beacfc5f	- except for DWORD, all homegrown integer types are gone - a handful were left where they represent genuine Windows types.	2017-03-09 19:54:41 +01:00
Christoph Oelckers	54a120d612	- do not process subsectors if rendering a stacked sector portal and the clipper is set to 'blocked', i.e. no visible parts are present. ... This solves the most severe occurences of sprites being drawn in front of a portal's contents. It is not a full fix, though, there's still some extreme cases where portals may glitch if some stuff gets between the camera and the actual portal area. Normally this has to perform a full check of the subsector against the portal's camera-facing linedefs but that's too costly for those rare cases where it may be an issue.	2016-07-23 10:23:34 +02:00
Christoph Oelckers	24526f7da5	- made adjustments to floating point bounding boxes for nodes and changes to the WarpBuffer function.	2016-05-01 11:56:45 +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.	2016-04-23 10:50:19 +02:00
Christoph Oelckers	5a2eac8f15	- floatified vertices and removed the now redundant fx and fy members. This needs an added check for polyobject origins, though, so that such subsectors don't get rendered.	2016-04-03 11:40:14 +02:00
Christoph Oelckers	af78937a15	- updated GL renderer.	2016-04-02 23:17:16 +02:00
Christoph Oelckers	348c384bb6	- fixed scaling of skies with unusual dimensions.	2016-04-02 22:18:42 +02:00
Christoph Oelckers	399d0974ab	- added GL render as of SVN revision 1600.	2013-06-23 09:49:34 +02:00
