449362dcb3 - better debug output. 2021-12-30 09:53:07 +01:00

7b14aacdf4 - match alignment of NPOT flat textures to the software renderer 
Tested in RR E1L4, sector 224+40, probably needs more checking in other places as well to confirm that it is correct there as well.

1a3b9f8ac0 - made several arrays holding sector related data dynamic. 2021-12-26 23:10:02 +01:00

838bed7800 - final cleanup of sectnum related stuff. 
Made sure that remaining uses of sector indices are safe to be kept and deleted a few redundant functions.

387a03c7ee - fixed triangulation via node builder for sectors with invalid walls. 
The array indices were not properly adjusted for the missing elements an

01abe7b2ac - addressed most unused/uninitialized variable warnings from MSVC. 2021-11-29 00:55:30 +01:00

6dcd7e2557 - do not crash on badly defined walls where the end point is missing. 2021-09-12 18:18:26 +02:00

5d3f7947bf - avoid calling the node builder to triangulate degenerate sectors. 
This tends to crash.

62a5a720e8 - Check for maps with bad setup of their wall lists. 
Lo Wang In Time's map 11 does not include wall 0 into its sector, which caused crashes when trying to triangulate this sector.

15635ec7c8 - fixed crash when trying to triangulate broken sectors. 
In these cases it is possible that the wall index may go below 0.

2b8a80c6ce - added the out-of-bounds vertex handler to the secondary triangulator as well. 
If SW does this, triangulation must not be attempted as it will inevitably fail.

0b181c67b9 - don't skip lines when an empty one gets deleted. 2021-05-23 17:22:29 +02:00

f212421547 - don't let the triangulator choke on empty sectors. 2021-05-23 17:19:01 +02:00

572f45ca53 - delete lines in proper order when eliminating a pair. 
Deleting the lower one first will delete the wrong second one.

cc1def8d77 - fixed: When the node builder is used for triangulation, all zero-length lines must be eliminated first. 
These can cause triangulation errors.

234f303348 - fixed typo in line segment culler. 2021-05-21 18:40:34 +02:00

716b8840af - when using the node builder to triangulate sectors we must delete overlapping walls. 
The node builder can create bad geometry from them because it does bad ordering when two lines facing in opposite directions overlap.

d097c8e635 - removed the non-functional and long abandoned level music alias feature. 
With RMAPINFO such a hack is no longer needed for anything.

30b1b046e4 - added an intermediate data structure to decouple the rendering from the immediate map data. 
This will be needed for sectors consisting of disjoint parts and for providing some help with addressing rendering anomalies

82bcd90755 - fixed some remaining triangulation issues. 2021-04-03 15:10:06 +02:00

f7dd0ec4a2 - use ZDoom's node builder for triangulating sectors that fail the simple approach. 
As it turned out, the triangulator only works fine for regular polygons, but creates incomplete meshes for sectors with multiple sections or some degenerate areas, which are quite common with swinging doors.
The node builder is more costly and creates wall splits, of course, but it does not create broken output for degenerate sectors so it's a good fallback.

dc234ea72d - implemented RR's geometry effect. 
The grossest of all gross render hack that were ever done with Build...

3c4429f2a8 - fixed sector mesh generator to allow sectors with non-continuous wall loops. 
Blood has a few such sectors.

4cc0afe587 - fixed texture coordinate generation for sloped planes. 
Since these depend on the slope, the sector's ceiling and floorz need to be the same as for the mesh when creating them.

15fb89d08f - workaround for SO interpolation potentially writing bad values to wall positions. 
That messed up interpolation code really needs to be thrown away and replaced later, for now this has to suffice.

a4174352c7 - keep separate sector compare data for floor and ceiling. 
Otherwise there can be problems if floor and ceiling change at the same time.

9cccd6f89b - store plane meshes without height information. 
This avoids retriangulation when just the plane's z changes.

d2a1f9ea88 - fixed issue with constantly regenerating sector ceiling triangle meshes. 2021-03-29 20:29:09 +02:00

b93502f0d0 - fixed bad assignments for vertex compare data in sector triangulator. 2021-03-29 10:15:06 +02:00

e0fe8d2ed9 - fixed interpolation issues with sector objects in SW. 
SO's vertex interpolation does not use the common framework so it got missed by the sector retriangulation checks.
We need to check two wall positions as well to make sure that sector movement is properly detected.

d9ff2fd1e2 - used display size for all texture positioning. 2021-03-28 18:22:30 +02:00

88706e8e13 - added a cache for the sector geometry. 
Now it only needs recreation if the sector changes.
