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

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.

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.

11f41a97d5 - made gotpic a FixedBitArray. 
gets rid of some inline garbage.

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.

a2e280e188 - use wallsofsector in 4 more places.

e79cd8d87f - don't store sprite indices in walltype::portalnum 2021-12-26 23:09:54 +01:00
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.

12f6b05cbe - use access functions, all done by search & replace. 2021-12-26 23:09:44 +01:00

2aefe4398b - sector[tspr->sectnum] globally replaced. 2021-12-26 23:09:43 +01:00
Christoph Oelckers
adf3133fdc - use sectnum and wallnum to get an index from pointers instead of subtracting the array base. 2021-11-29 00:56:26 +01:00
Christoph Oelckers
01abe7b2ac - addressed most unused/uninitialized variable warnings from MSVC. 2021-11-29 00:55:30 +01:00

9d36e61d3f - depth bias fixes. 2021-06-09 00:47:13 +02:00
Christoph Oelckers
a32489be31 - wall sprite positioning tweaks. 
Turns out that a distance of one Build unit from a wall alone is not enough to render them glitch-free, some depth bias is still needed.

3c5ef9c8e6 - properly render geometry that's fully shrouded in fog. 2021-06-01 21:48:39 +02:00
Christoph Oelckers
264d42179e - optimized the wall drawer a bit to avoid repeated calls to the render API's deoth bias function. 
The setters in FRenderState should check if the value actually changes and the wall drawer should only call it for non-translucent wall sprites.

f7a424cd06 - fixed precision issues with GetClosestPointOnWall for orthogonal lines. 
The math failed for some large wall sprites (e.g. Blood E2M4, sprite #181), and in orthogonal cases it is better anyway to perform direct checks of the coordinates
 2021-05-21 18:25:30 +02:00

079a95a0a3 - use a higher depth bias for non-orthogonal wall sprites. 
Due to minor angular inaccuracies they are more sensitive to z-ordering than orthogonal ones when things are closely stacked.

5cfd810311 - new renderer: take fog properties for walls and ceilings from the proper elements. 2021-05-20 19:17:21 +02:00

b5358bc03c - fixed typo in wall sprite offsetting code. 2021-05-20 18:25:19 +02:00
Christoph Oelckers
d4eb54d686 - render free standing wall sprites without depth bias. 
Otherwise they can end up badly ordered with walls.

a348508779 - handle the wall sprite clipping properly. 2021-05-16 16:00:00 +02:00
Christoph Oelckers
5bb438b817 - new renderer: fixed bad positioning when a y-flipped wall sprite had to be clipped to floor or ceiling. 2021-05-16 12:17:26 +02:00
Christoph Oelckers
845ce63348 - make sure that all objects rendered as shadow reset the object color after the draw call. 2021-05-15 10:40:25 +02:00
Christoph Oelckers
b644000b02 - fixed texture y-flipping on bottom tiers of walls. 
The flip flag was taken from the wrong side of the wall.

Christoph Oelckers
29b0106a96 - fixed yet another problem with the local 'sprite' variables in HWWall causing problems. 
This variable and its companions in HWFlat and HWSprite have now been renamed to avoid these issues.

dc0df7d081 - don't clamp shade values in the setup pass. 
We need their proper values when setting up the lighting.
 2021-04-21 22:32:27 +02:00

be20b6a839 - fixed: wall sprites do not need NPOT emulation. 2021-04-20 16:58:18 +02:00
Christoph Oelckers
d078b511b8 - flip backwards oriented wall sprites before submitting them to the render list. 
Backwards orientation will break the translucent object sorter so this needs to be sorted out beforehand.

bf019ac028 - Build must draw the sky for completely closed sectors as well. 2021-04-12 16:31:44 +02:00

2e191f2742 - consolidated the SetLightAndFog code fragments. 2021-04-10 10:34:20 +02:00
Christoph Oelckers
345275db5d - better handling for portal lines having sloped back sectors. 
This is a very ugly special case that probably needs a bit more work to get right, for now this should be enough as this combination is rather rare.

c9483353ff - some more translucency checks. 2021-04-08 19:56:18 +02:00
Christoph Oelckers
1362a7ebc5 - added extended translucency support and did a bit of code consolidation. 2021-04-08 19:45:18 +02:00
