8a20f901a3 - removed the non.slope special handling in the wall processing code.
This may have made some sense when I added this 11 years ago but on a current computer it actually hurts performance a bit due to the branching that is involved - the code runs a bit faster with those special cases removed.

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

3683a8ac58 - implemented line-to-line portal rendering. So far working for two-sided portal lines - one-sided yet to come. 2016-02-06 12:32:47 +01:00
Christoph Oelckers
297cf52ac9 - copied line portal code from portal branch and made some adjustments to make it compile. Portal rendering is not yet working. 2016-02-06 05:17:47 +01:00

c129cb3ca4 - reinstated software clipping by light volumes for walls.
It turned out that using hardware clipping planes exclusively to handle this cost more than it gained.
Now only the expensive or formerly impossible cases of intersecting light volumes or light volumes intersecting with the top and bottom of the wall polygon will use hardware clipping. The trivial cases will go back to software splitting.

67fc35e738 - some cleanup of wall processing code.
* removed SplitWall function
 * split PutWall into PutWall and PutPortal because none of the portal cases needs the overhead for normal walls.

9305cd86a0 - remove the GLWallLightEntry type. Everything it contains can be retrieved from the existing lightlist just as easily, and this approach avoids a lot of memory allocations.
- removed the SplitWall profiling timer because all it measures now is an almost empty function.

53a389aafc - fixed: for untextured walls, the texture must be disabled before rendering.
- fixed: untextured walls should never be passed to SplitWall.
- fixed: untextured walls should not be affected by dynamic lights (it's either fog boundaries or outsides of 3D fog volumes.)

9ce6a7932c - implemented rendering of 3D lights with clip planes. 2016-01-31 22:04:20 +01:00

5448b335c6 - rewrote render loop for walls. Not working yet. 2016-01-31 21:10:59 +01:00

1d9ab5c632 - clean out GLWall::SplitWall and instead of actually splitting the wall just attach a list of lights to it.
Actual handling will be in the rendering function because this doesn't need multiple vertex transfers to the GPU. All slices can be drawn from the same buffer with different uniform info being set.

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

65022b780a - implemented 'copy portal to wall' linedef type. 2016-01-11 22:44:53 +01:00

ef7bcb3a66 - implement Eternity-Style flat and horizon portals. Not tested yet due to lack of material to work with. 2016-01-11 15:07:58 +01:00

7d2bbbd351 - fixed rendering of two-sided polyobjects that have their upper or lower textures exposed. 2016-01-05 18:59:32 +01:00
Christoph Oelckers
c8810db5fe - fixed: clipping swimmable against non-swimmable translucent 3D-floors was broken due to an incorrect flag check. 2015-12-24 16:34:00 +01:00
Christoph Oelckers
f9cbaef1df - fixed: Boom's Transfer_Heights did not work for upper parts in sectors with a sky ceiling.
This incorrect check has been in the code for 12 years, unfortunately I have no idea anymore why it was added.

8a9692c29f - fixed: The code which decided whether to clamp two sided middle textures used the texture size instead of the render size for the specific linedef, meaning that any per-sidedef scaling was ignored. 2015-02-10 20:16:25 +01:00
Christoph Oelckers
fbfe0f1e7a - fixed: y-clamped textures with negative scale need to shift their texture coordinates into the proper [0..1] range. 2014-12-26 11:53:38 +01:00
Christoph Oelckers
9f1f17c306 - fixed: The PolyBSPs weren't fully initialized. Some GZDoom-only fields in the segs were skipped. 2014-10-14 08:54:08 +02:00

fa3a62e954 - fix a render glitch with Back to Saturn X MAP06: Do not flood missing upper and lower textures with the backsector's flat if that backsector is malformed (i.e. has no area.) 2014-08-31 23:01:53 +02:00

49ec7beb8f - separate draw lists for walls and flats. This makes the sorting much more efficient because draw types no longer need to be checked in the compare function. This is a lot more important than having perfect texture order. 2014-08-30 13:04:41 +02:00

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.

b9ffb51d0c - small but important optimization: Two-sided lines with both sides in the same sector don't really require vertex splitting for precise rendering. 2014-08-04 23:00:40 +02:00

1ec58011d2 - start of light buffer implementation so that we don't have to use uniform arrays which appear to be broken on AMD. 2014-07-31 00:44:22 +02:00
