ab9c7de147 - use texture clamping for all sprites. 2021-03-29 20:18:49 +02:00
Christoph Oelckers
2d0360fa55 - apply depth bias to translucent geometry. 
This is necessary to handle wall and floor sprites placed on actual walls and floors work as intended.

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

0ae93318e3 - flip camera textures to have the correct orientation. 2021-03-28 21:00:24 +02:00
Christoph Oelckers
e8edb32e0d - fixed camera texture setup. 
They still are upside-down but aside from that work as expected.

d3e0a9590c - renderDrawMasks may only be called for Polymost. 2021-03-28 15:14:32 +02:00
Mitchell Richters
6f65eb2270 - Duke: Amend 7e8ef99ec9 to adjust view height where it was originally adjusted. 
* Doing this in `renderView()` unconditionally isn't correct as it can lead to a double adjustment if `p->spritebridge == 0 && p->newOwner == nullptr`.
 2021-03-28 23:21:07 +11:00

7e8ef99ec9 - fixed view height in Duke. 2021-03-28 13:38:27 +02:00
Christoph Oelckers
83760d4974 - fixed a few wall sprite rendering issues. 
* masked walls were inserted into the sprite render list, causing sorting issues and depth fighting (see Duke's cameras and the 'closed' sign in Route66/Carnival.map)
* vertical and horizontal wall sprites needed their sorting functions swapped.
* plane clipping for wall sprites used bad coordinates.

9f48b36627 - redid sprite projection math. 2021-03-28 10:49:34 +02:00
Christoph Oelckers
fa44d75e98 - draw regular sprites. 
Mostly functional, but the projected size is off.
 2021-03-27 23:12:41 +01:00

7c991d59ac - fixed bad return in sprite processing code. 2021-03-27 15:52:20 +01:00
Christoph Oelckers
0da33096c6 - fixed some wall sprite flickering issues. 2021-03-27 15:24:09 +01:00
Christoph Oelckers
e7d73fd8e7 - fixed clipping code. 
This seems to require the old code as-is - the latest refactoring broke some stuff again and had to be reverted.

d1c23d1ad0 - fixed wall sprite rendering. 2021-03-27 14:18:33 +01:00
Christoph Oelckers
efe0d57fca - removed all the decal stubs. 
Build has wall sprite for decals so this is redundant and ultimately not usable.
 2021-03-27 13:26:11 +01:00

d0f38d7362 - wall sprite WIP. 2021-03-27 13:22:34 +01:00

1dfb2672a8 - flat sprite rendering! 2021-03-26 20:28:44 +01:00
Christoph Oelckers
fd0e9824b6 - call the game specific analyzesprites functions. 2021-03-26 15:06:14 +01:00
Christoph Oelckers
098db655ab - did some fudging on the scene viewport until thinks looked right again. 
I have no idea, though, why it has to be this particular formula, though. It doesn't seem to make any sense.
 2021-03-26 01:55:24 +01:00

be7bca8e9e - expose animatesprite set of functions to new renderer as a callback. 2021-03-26 10:05:01 +01:00
Christoph Oelckers
0b1e81023f - added sprite collection loop to ProcessSector and did a bit of cleanup on the TSprite code. 2021-03-25 23:16:32 +01:00
Christoph Oelckers
f6568fee0c - rewrote SW portal setup to use static data instead of ad-hoc setup. 
This was by far the messiest game, there's two reasons for this.
First, the portal links do not need to be in an actual portal sector, so they cannot be used to detect portal sectors.
Second, the game moves portals in place, so all offsets are (0,0,0) so that not even these can be used for detection.

The only working method is the super-complicated original way to look up portals at run time, just being done at map start.
Having static portal links should reduce the render glitches quite significantly because the renderer knows now which sectors belong to a portal and can use this information to ensure proper processing.
 2021-03-25 21:21:48 +01:00
Christoph Oelckers
af54cf3a3c - made SW's sector portals operational. 
Unlike the other games these are so poorly defined that the engine has to rely on the original fudging to pick the proper portal to link to. As a result they are just as limited as they always were.
In addition all the portal search code had to be reinstated.

168b0385cf - moved shadeToLight out of build.h. 2021-03-25 09:13:59 +01:00
Mitchell Richters
957f7e9487 - Accept binangle, fixedhoriz and lookangle classes in SetupViewpoint() vs. Q16.16 variables. 
* Allows for more precision than Q16.16.
* Used as opportunity for `rollang` to be set using the `asdeg()` method, not `asbuildf()`.

13bbf0a4f9 - sector portals in RRRA are working. 2021-03-24 23:55:10 +01:00
Christoph Oelckers
dbbdfaa4ba - sector portals in Blood are working. 2021-03-24 23:11:06 +01:00
Christoph Oelckers
368b2319f2 - replaced 'static FORCE_INLINE' globally with 'inline'. 
I have no idea what kind of compiler needs such a construct, it's totally not how C++ should be written.
 2021-03-24 21:43:36 +01:00
Christoph Oelckers
b7e8815133 - some further lightening of compat.h. 2021-03-24 21:13:36 +01:00
Christoph Oelckers
8993095bc0 - got rid of pow2char 2021-03-24 20:37:20 +01:00
Christoph Oelckers
d8627a2b3f - removed all remains of projection math weirdness from the automap code in the games plus a bit more cleanup of the engine code. 2021-03-24 20:28:58 +01:00
Christoph Oelckers
022edd2dc2 - cleaned engine.cpp off all code exclusive to the Polymost renderer. 2021-03-24 19:45:42 +01:00
Christoph Oelckers
e47b4507e4 - serialize the sector portal offset table. 
Due to where this happens, the init code for these portals cannot be run when loading a savegame so it has to be saved.
 2021-03-24 18:42:00 +01:00
Christoph Oelckers
1297e4ed02 - SW's line to sprite portals are working now. 
Also fixed a clipper issue with Blood's line to line portals.
 2021-03-24 10:33:50 +01:00
Christoph Oelckers
9903b39cf5 - make Blood's line to line portal operational. 
Note that these portals cannot be rotated, so to preserve bad setups this limitation needs to be replicated.
If we want proper line to line portals for all games they need to be made a different portal type.
 2021-03-24 09:04:48 +01:00
Christoph Oelckers
829be9b56b - use value parameters for arguments in binaryangle.h. 2021-03-24 09:02:07 +01:00
Christoph Oelckers
087da46522 - finally got mirrors working. 2021-03-23 21:23:49 +01:00
Christoph Oelckers
c681fa6699 - use Build math for mirror transitions. 2021-03-23 20:30:19 +01:00
Christoph Oelckers
46e0b16370 - fixed ordering issues in drawer 
* do not check the clipper in the collection pass to reduce number of bunches. Clipping here brings no performance gain.
* fixed the loop reset in FindClosestBunch to actually process the array's first element.
 2021-03-23 19:20:06 +01:00
Christoph Oelckers
0c7f05a416 - let the clipper work exclusively on Build coordinates. 2021-03-22 23:40:25 +01:00
Christoph Oelckers

Christoph Oelckers
75159e06c0 - uncommented the portal code in hw_walls.cpp. 2021-03-21 19:36:55 +01:00
Christoph Oelckers
9fe462d358 - adapted GZDoom's portal framework. 
Not tested yet and somewhat stripped down, as the portals this needs to support are a lot less complex - plus some of the issues in Doom do not apply here.
 2021-03-21 18:41:23 +01:00
Christoph Oelckers
98e4a3035d - updated the earcut.hpp triangulator. 
The old one wasn't triangulating the bathroom sector in DUKEDC2 properly, the bug got fixed upstream in the mean time.
 2021-03-21 17:18:15 +01:00
Christoph Oelckers
09a9e14feb - set up engine portals for SW. 
Also moving more code to _polymost.cpp which is only needed for ad-hoc lookup of portals with a client side implementation of a two-layer renderer.
 2021-03-21 17:04:06 +01:00

757d7be18b - updated the earcut.hpp triangulator. 
The old one wasn't triangulating the bathroom sector in DUKEDC2 properly, the bug got fixed upstream in the mean time.
 2021-03-21 11:54:39 +01:00
Christoph Oelckers
ecd6e68d69 - made render call adjustments to Exhumed. 
This one was easy - no special cases at all. :)
 2021-03-21 11:48:18 +01:00
Christoph Oelckers
6f7e7459ea - did some cleanup on Duke's render code to prepare for the new way of handling portals. 
Like for Blood, the Polymost-only code has been moved aside.
Closer examination of the preparations the engine is doing for rendering SE40/150-portals shows that all this was merely done to avoid glitches with a two-phase rendering setup - nothing of this will be needed for doing it properly.
They can just be treated as run-of-the-mill stacked sectors. when using hardware rendering capabilities for clipping.
 2021-03-21 10:58:11 +01:00
Christoph Oelckers
9f36ef69e6 - fixed variable name clash caused by viewUpdateShake's global variables. 
removed the redundant call in the Ticker, because all its results are discarded.
Use arguments instead of global variables to pass data around.

4109a256ac - Blood: cleanup of render code. 
Renaming of disassembly variables and moving of disabled Crystal Ball renderer to a separate function.
 2021-03-20 19:20:42 +01:00
Christoph Oelckers
f30a568858 - moved wallfront function into polymost.cpp. 
This was one of the few functions left in engine.cpp that accesses the global scene state.
 2021-03-20 19:10:46 +01:00
Christoph Oelckers
91957e40f1 - moved some original Raze code out if the Build folder. 2021-03-20 17:08:55 +01:00
Christoph Oelckers
fedfc2cfa4 - removed global variables that were only being used by the automap drawer plus a few other obsolete things. 2021-03-20 16:46:06 +01:00
Christoph Oelckers
30f4e2b29d - replaced the engine automap drawer with one leveraging the newly added sector geometry data. 
This eliminates a lot of code depending on Build's projection math.
 2021-03-20 16:20:48 +01:00
Christoph Oelckers
88706e8e13 - added a cache for the sector geometry. 
Now it only needs recreation if the sector changes.
 2021-03-19 23:18:09 +01:00
Christoph Oelckers
5a0c8da6bf - Duke: fixed some incorrect assignments in CON parser 2021-03-19 23:18:09 +01:00
Christoph Oelckers
3df5c440f9 - added some helpers to make it easier to determine if a sector's geometry has been altered. 
Walls had no sector reference so this was added for marking the sector as altered when a vertex gets dragged around.
 2021-03-19 23:18:09 +01:00
Mitchell Richters
895b875453 - Invert rollang in hw_entrypoint.cpp:SetupView(). 2021-03-20 08:35:17 +11:00
Christoph Oelckers
93bb774573 - flat alignment. 
This still gets redone each frame for each sector and needs to be buffered
 2021-03-19 19:53:55 +01:00
Christoph Oelckers
a5b3a1dd3e - removed some unused things from engine.cpp. 2021-03-19 15:12:54 +01:00
Christoph Oelckers
76682c72e3 - removed krecipasm. 
Analyzing the results, this is not needed as its precision is virtually the same as floating point math, so its one use got replaced.
 2021-03-19 14:23:41 +01:00
Christoph Oelckers
dd15fc54c1 - top texture means RENDERWALL_TOP, not that it matters much at the moment... 2021-03-19 12:02:20 +01:00
Christoph Oelckers
ff8ca99e2b - fixed y alignment of bottom textures. 
Despite other settings, they will always take the panning info from their backside.
 2021-03-19 11:51:38 +01:00
Christoph Oelckers
f8de712b81 - fixed horizontal panning for bottom textures. 2021-03-19 11:22:24 +01:00
Christoph Oelckers
385cc8cbbd - NPOT texture alignment fixes. 
The checks in CheckTexturePosition were not correct and caused unwanted texture shifting.
Also inlined GetYPanning into DoTexture because the pow2size value is needed there and the rest is a simple one-liner to scale the panning.
 2021-03-19 10:29:38 +01:00
Christoph Oelckers
9406e6d2ad - fixed the biggest issues with flat rendering 2021-03-18 23:22:51 +01:00
Christoph Oelckers
7dd5b508c8 - flat rendering WIP. 
Still buggy triangulation and no texture alignment, but it renders something.
 2021-03-18 21:50:02 +01:00
Christoph Oelckers
0579368626 - removed render.cpp, now that everything is in its proper place. 2021-03-18 17:24:58 +01:00
Christoph Oelckers
547ed4e415 - route everything through the full backend, now completely bypassing the intermediate GLInstance layer. 2021-03-18 17:18:03 +01:00

c4b3523f05 - moving utilities to more appropriate places. 2021-03-18 12:49:33 +01:00
Christoph Oelckers
6068427270 - port the bunch drawer to the backend's core. 2021-03-18 12:32:31 +01:00
Christoph Oelckers
af6c6c8ef0 - added the DrawInfo class. 2021-03-18 10:23:53 +01:00
Christoph Oelckers
e9dd1c104b - started adding the draw list code from GZDoom. 2021-03-18 10:19:13 +01:00
Christoph Oelckers
0f28069f96 - fixed NPOT shader parameters. RR E1L1's hedges render properly now. 
- fixed a few places where wall[0] was accessed.
 2021-03-18 09:20:38 +01:00
Christoph Oelckers
2d958745b4 - fixed: Polymost must set the viewpoint if renderers are switched. 
- fixed coordinate order in renderSetViewpoint
- fixed backwall checks accidentally testing wall 0 instead of the current wall.
 2021-03-18 00:28:38 +01:00
Christoph Oelckers
493294909b - fixed texture alignment 
Most cases should be correct now.
 2021-03-17 23:29:13 +01:00
Christoph Oelckers
47dce8de8c - partially fixed y-panning and removed the aspect factor. 
y-panning is still not correct for all cases but better than before. The aspect factor is not needed, it looks like an artifact of both the software renderer and Polymost.
We get the same dimensions with proper matrices by setting this to 1.
 2021-03-17 20:02:50 +01:00
Christoph Oelckers
65097c4098 - set proper visibility factor and viewport. 2021-03-17 19:07:00 +01:00
Christoph Oelckers
b492cbcebb - ported my old Build-style renderer for Doom from 2008 and the wall renderer from GZDoom to work with Build data. 
It renders walls, but y-panning is still broken.
 2021-03-17 16:54:36 +01:00
Christoph Oelckers
9ebd8fd4a5 - put all of Polymost in a namespace. 
So that its static variables are properly separated from the rest.
 2021-03-17 15:55:25 +01:00
Christoph Oelckers
c6f83fa8bd - added GZDoom's clipper. 2021-03-15 19:11:18 +01:00
Christoph Oelckers
a484e39e05 - removed integer square root code. 
On modern systems using the sqrt function with a cast to int has no relevant performance disadvantage anymore so there's no need for all of this.
 2021-03-15 19:02:08 +01:00
