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

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.

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

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.

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.

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