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 096ce5e025 - initial sky fixes. 2021-03-22 16:02:52 +01:00
Christoph Oelckers e884a418f8 - portal WIP 2021-03-22 12:07:29 +01:00
Christoph Oelckers cecfbb76e8 - fixed uninitialized clear color variable. 2021-03-22 12:07:15 +01:00
Christoph Oelckers 63f057d93f - portal and sky WIP. 2021-03-21 22:48:01 +01:00
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 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
Christoph Oelckers a36377111c - engine-side portal setup for Blood and RRRA. 2021-03-21 14:48:35 +01:00
Christoph Oelckers b91441f849 - same render interface rework for Shadow Warrior. 2021-03-21 12:22:50 +01:00
Christoph Oelckers 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.

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.
 2021-03-21 08:58:38 +01:00
Christoph Oelckers d42ce0ee7e - WIP 2021-03-20 23:01:16 +01:00
Christoph Oelckers 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
Christoph Oelckers 4cf2493cfd set up the entry point for the renderer. 2021-03-18 14:49:36 +01:00
Christoph Oelckers 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.
