98c919fbe4 - g_visibility stuff 2022-01-11 00:12:32 +01:00
Christoph Oelckers
ddcee4ecbf - split up g_visibility into two variables. 
This is preparation for experimenting with the weapon flashes that can be quite annoying with how they brighten distant parts of the level far more than nearby parts.

91d51d518b - this hack is needed because dragging vertices around can randomly create wall intersection. 
In clear English: Geometry in Build maps is always broken by design. :(

Christoph Oelckers
a0e6ee0e2e - added a bit more logic to handle overlapping walls. 
All this is needed to make the back door to the cinema in Duke E1L1 render properly without making the clipper break on complex overlapping sector setups, like some of the ducts in Duke E2L7.

fcba341546 - use proper aspect ratio to calculate the frustum's angle. 2022-01-08 23:43:08 +01:00
Christoph Oelckers
415dc5246d - fixed sprting of non-translucent sprites. 2022-01-08 21:18:18 +01:00
Christoph Oelckers
0cfe6bbed3 - do the unlink properly when replacing a clip node. 2022-01-07 00:22:02 +01:00
Christoph Oelckers
98258e0bb2 - fix handling in the clipper for a new range that completely covers an existing one. 
The handling for this was from the first draft of the clipper that made very different assumptions than the final version.
This cannot simply delete the old range - it has to explicitly alter it and recursively insert the outer sub-ranges separately.
 2022-01-06 16:34:04 +01:00
Christoph Oelckers
159409d5d2 - allow a bit of tolerance when sorting walls, so that microscopic intersections can be ignored. 2022-01-06 00:43:47 +01:00
Christoph Oelckers
9f6d6a0e6d - block y-flipping of slope sprites only if they are actually sloped. 
This mirrors Polymost's (buggy) handling.
 2022-01-05 09:20:54 +01:00
Christoph Oelckers
d5daa8ee84 - fixed: The bunch drawer's gotwall array was cleared before resizing. 
This means that on the first frame of a new map it'd operate on partially uninitialized data.
 2022-01-04 17:18:26 +01:00
Christoph Oelckers
227ac0fca6 - RR: address a missing texture in E1L2. 
The current texture on this wall is suboptimal but it's still better than glitchy HOM.
 2022-01-04 17:18:25 +01:00
Christoph Oelckers
ac3546bdaa - fixed depth buffer use of slope sprites. 
They cannot be treated like perfectly horizontal floor sprites and need to write to the depth buffer in the same pass as the regular pixels.
 2022-01-04 12:42:45 +01:00
Christoph Oelckers
e2e3b4482d - do some better sorting of slope sprites. 
Splitting by translucent floor plane is essential, splitting by wall not that much - sorting by center point should be sufficient here.
 2022-01-03 12:31:54 +01:00
Christoph Oelckers
daa07b9e55 - an attempt to render "reflection" floor sprites by lifting them up to the floor and drawing them with 33% alpha. 2022-01-01 20:01:36 +01:00
Christoph Oelckers
6807086f3c - relaxed the FindWall check for wall sprites a bit so that slightly out-of-sector sprites can find a wall to attach to. 2022-01-01 18:55:42 +01:00
Christoph Oelckers
fcb3e43799 - fixed side check for sloped sprites. 2022-01-01 17:27:09 +01:00
Christoph Oelckers
9680ff1863 - ignore y-flipping when rendering slope sprites in the new renderer. 
This is what Polymost, and apparently NBlood, do here.
 2022-01-01 12:55:28 +01:00

733b6a7367 - Fix GCC warning warning: ‘vec.TVector2<double>::X’ may be used uninitialized [-Wmaybe-uninitialized]. 2022-01-01 20:50:58 +11:00
Christoph Oelckers
f679b61a30 - fixed issue with wall sprite angle check. 
The resulting value had no sign, so 'abs' did not work. It now uses some bit shifting magic to get a proper sign.
 2021-12-30 22:56:33 +01:00
Christoph Oelckers
a9b162b8e9 - moved the tsprite flags from cstat2 to clipdist which was already holding other ones. 
cstat2 should only hold flags for game-side sprites.
 2021-12-30 19:00:35 +01:00
Christoph Oelckers
6c381d4392 - removed sector() method from low level sprite type. 2021-12-30 16:58:48 +01:00
Christoph Oelckers
88e4bb9f79 - moved sectno method to DCoreActor. 2021-12-30 16:39:43 +01:00
Christoph Oelckers
eb00fe52db - more spritetype references eliminated. 2021-12-30 16:11:14 +01:00
Mitchell Richters
9bbb54fe2e - Replace every line that just contains spaces or tabs with an empty line feed in all files except 3rd party libraries. 2021-12-30 20:30:21 +11:00
Christoph Oelckers
e670cf2786 - re-tabified several files that got mangled by repeated merging 2021-12-30 09:58:47 +01:00
Christoph Oelckers
d46a7abb0e - better wall sprite handling. 
When they are directly on a wall, project their coordinates onto the wall to eliminate the imprecisions from Build's ad-hoc setup.
 2021-12-30 09:58:46 +01:00
Christoph Oelckers
1a2b9d43f7 - fixed check for wallsprites on walls. 
This completely ignored the case where a wall was flagged as one-sided which was the main reason with that sneaky sign in E2L1.
The problem is not entirely fixed with this but now it will detect that it's on a wall.
 2021-12-30 09:58:46 +01:00
Christoph Oelckers
b1d8f92ded - added wall edge splitting for gl_seamless. 2021-12-30 09:58:44 +01:00
Christoph Oelckers
f7e7476010 - hooking up the vertex map with the rest of the engine. 2021-12-30 09:58:44 +01:00
Christoph Oelckers
059412b75e - first batch of routing all write access to sectortype::ceilingz and floorz through a function interface. 
We need this for implementing "precise" rendering to flag vertices as dirty.
 2021-12-30 09:58:14 +01:00
Christoph Oelckers
e5c9691166 - fixed clipping issue with sloped walls. 
The window was calculated too narrow for this case, it needs to use the lower point of a floor slope and the upper point of a ceiling slope.
 2021-12-30 09:58:09 +01:00
Christoph Oelckers
50bad91f14 - handle edge case in clipper where adding a new window will remove the entire clipper's content before adding the new range. 
This case would have passed the actual logic but not the asserts.
 2021-12-30 09:58:09 +01:00
Christoph Oelckers
9e14b168bb - addressed more shadowed variables in common code. 2021-12-30 09:57:32 +01:00
Christoph Oelckers
3992dfae84 - fixed: When merging clip nodes the redundant one needs to be deleted with RemoveRange. 
Calling Free is not enough.
 2021-12-30 09:57:29 +01:00
Christoph Oelckers
b00f197be3 - fixed: RemoveClipRange did not shorten the range if it had to split it up. 2021-12-30 09:57:29 +01:00
Christoph Oelckers
5699488bea - get rid of spritetype in inactive code. (Search noise removal) 2021-12-30 09:57:20 +01:00
Christoph Oelckers
40a307650d - the really final parts of the shared code using s() cleaned up. 2021-12-30 09:57:15 +01:00
Christoph Oelckers
09634c4993 - use actors instead of sprites in the new renderer's API. 2021-12-30 09:57:15 +01:00
Christoph Oelckers
f602cf3806 - deal with s() in shared code. 
clip.cpp was left alone, except for the actual call.
 2021-12-30 09:57:14 +01:00

Christoph Oelckers
beddf1e1ca - add slope sprite support to the new renderer. 
Some fudging was needed to avoid positioning problems as the renderer is more sensitive to this than Polymost.

Christoph Oelckers
c141c89cfd - fixed the clipper. 
* must do proper checks for merged ranges when inserting new ones. The checking code assumes that closed ranges are contiguous.
* when discarding parts of overlapping ranges this may not use merged clip values for its checks.
* ranges that have their clip values altered must be released and reinserted to ensure everything is correct.

gets rid of some inline garbage.
 2021-12-30 09:53:56 +01:00
Christoph Oelckers
dddf48fd3e - cleaned up and renamed buildtypes.h. 
Content was reordered so that the file can contain the inlines belonging to the map data types that previously had to be stored elsewhere.
Also moved out of the Build folder because virtually everything in here can be traced to content available in Duke Nukem 3D's and Shadow Warrior's source releases.

4a5de6f56e - make sure that all changes of wall coordinates invalidate associated data. 
walltype::move should be the preferred function to be used for this, otherwise walltype::moved needs to be called.

0e6242626c - removed the viewpoint from the clipper as we don't need this.

Christoph Oelckers
eaff9e359f - refactored the owner index in tspritetype. 
This is now a separate type from spritetype which contains an actor pointer instead so that sprite display can be handled without requiring a static sprite array.

054d81fc8e - fixed logic for discarding walls in new renderer. 
The case being checked here may decide not to add the wall to the clipper but it must still be rendered.
Information for determining visibility is not sufficient in case of sector overlaps which can happen with rotating doors or poorly set up sector objects.
