d4b32bf79f - fully synchronized the backend code with GZDoom. 
The camera texture code couldn't be done earlier.

5effc95ae1 - updated startup dialog and fixed multisampling not active in the 3D scene. 2020-06-14 20:59:26 +02:00

67b1963e7c - fixed render state management. 
There are effectively two states - the one in the backend and a local one in the drawer for the render list which is supposed to eliminate some of the more costly repeated calls.
This higher level state was cached globally, which did not work anymore because the real render state could be changed elsewhere without this code realizing it.
All this means that the render list drawer must create a new state cache for each call and also must apply its current pending render state before leaving to ensure that everything is properly reset.

60b18c7ec9 - Blood: use the 2D drawer to clear the screen for 2D display. 2020-06-12 20:31:23 +02:00

6a9f1e9da1 - removed the old OpenGL interface. 2020-06-12 00:25:52 +02:00

ba397f5ca1 - always draw floors opaque 2020-06-11 23:55:23 +02:00

22aad4999c - use the engine backend to render the scene 2020-06-11 22:26:46 +02:00

17e1e4175e - switched NPOT emulation to the renamed uniforms. 
This was the last feature that needed to be mapped to a GZDoom compatible render state

a6545788a6 - do RR's lightning flash as a postprocessing effect. 2020-06-07 22:06:47 +02:00

d7225c1965 - backend update from GZDoom 2020-06-07 15:02:54 +02:00

9fc5f2d2e7 - some shader cleanup. 
I think it's now as close to GZDoom's backend interface as it can be without disabling needed features.

353e3eb1fa - fixed RRRA E2L1 fog. 2020-06-07 08:24:12 +02:00

3adfdfcac5 - renamed a few more things in the shader. 2020-06-07 08:16:04 +02:00
Christoph Oelckers
232b0c1bb6 - store the lighting related uniforms in a GZDoom-style LightParms vec4. 2020-06-06 00:44:57 +02:00
Christoph Oelckers
f159496f6e - moved the ShadeDiv array into the lookup table and took the numshades-2 divisor out of the stored value. 
The value was changed to allow easier reuse in scenarios where the size of the shade table does not matter anymore.

0bd460d9e3 - split up the visibility factor into a scene specific and an element specific part. 
The main reason here is that the scene specific part contains a projection dependent component which would be a problem when transitioning to GZDoom's code. The global viewpoint data already has a field for such a factor so now that gets used.
This also means a significant simplification of the visibility code in Polymost and the removal of several global variables.

9dfd3ddd02 - migration of texture tinting to GZDoom's version. 
- start of visibility migration - removing unused globvis variable.
 2020-06-05 17:02:21 +02:00

d812c2997c - start renaming uniforms to match GZDoom. 
Needed to allow using the same shader with the backend.
 2020-06-04 21:34:27 +02:00

b15cc31a38 - transitioned matrix setup to use the backend's uniform buffer implementation. 2020-06-04 20:14:48 +02:00
Christoph Oelckers
cf6855904d - took projection and view matrix out of the render state. 
This is a preparation to migrate to GZDoom's HWViewpointUniforms buffer.

bd0c8acd46 - replaced detail matrix with a two element scale vector because that is all that is needed. 2020-05-31 12:23:35 +02:00
Christoph Oelckers
d752e33909 - removed the unused SurfaceShader class. 2020-05-31 11:47:19 +02:00
Christoph Oelckers
611dad7f69 - added the softpoly and Vulkan backend code fron GZDoom. 
Not hooked up yet.

1d15fe63a6 - another backend update, pulling in the sky renderer. 2020-05-31 10:32:10 +02:00
Christoph Oelckers
1e2a3da5fd - video base code unified. 
# Conflicts:

edb2cb31ee - backend update with GZDoom model code. 2020-05-31 08:55:00 +02:00

58c62e071c - use FMaterial. 2020-05-30 22:20:06 +02:00

423f758314 - texture code restructuring. 2020-05-30 21:42:35 +02:00
Christoph Oelckers
cdcb25bc1f - use high level textures to render voxels. 2020-05-30 00:30:56 +02:00
Christoph Oelckers
87a87c155d - moved to GZDoom's gl_hwtexture.cpp. 2020-05-29 01:03:01 +02:00
Christoph Oelckers
72889540a5 - use GZDoom's gl_samplers.cpp 2020-05-28 23:48:50 +02:00

758e4ad7cb - stripped down the palette manager in the GL backend and let it use the data that's managed elsewhere. 
This class is only needed to manage the palette textures used by the indexed render mode, all the rest is available globally.

ab6e87b5f8 - workaround for Ion Fury display glitches on the first map. 
I have no idea why this needs to be different than in EDuke32, but without always clearing the depth buffer before rendering a scene viewpoint the game will glitch like crazy.

d46ea7481f - handle RRRA E1L2's fog in the shader instead of hacking the shade tables. 2020-04-12 08:30:43 +02:00
Christoph Oelckers
5584c726ba - file system update and adjustment. 2020-04-12 08:30:40 +02:00

41545b644a - cleaned out most of the software renderer's static global variables. 2020-03-29 16:59:49 +02:00
Christoph Oelckers
3f69044770 - removed all references to sdlayer.cpp as all that was left in there was only needed for software rendering. 
- removed now unused a-c.cpp.

286d53d3bf - added the missing handling for the basepal tinting. 2020-02-11 20:55:47 +01:00
Christoph Oelckers
215cb14401 - use a non-0 depth bias for sprites. 
Hopefully this helps fixing the z-fighting issue with wall sprites in some Blood maps.

b066f725d4 - clear the matrix list after rendering the 2D content. 2020-01-19 23:27:59 +01:00
Christoph Oelckers
c8fa2443d3 - completely separated view and model matrix. 
This way the view matrix will remain constant per scene and an update of the model matrix is only needed for rendering a model or voxel, reducing the total amount of generated matrices to the point where they can be written to a buffer instead of constantly uploading them as uniforms.

b209b1f960 - make sure that the first matrix is always the identity matrix. It was just random luck that it was always put there before. 
- let the matrix setters return the previous value for easy restoring without creating yet another matrix.

454f796b69 - collect all 3D geometry in a list so that it can be rendered later. 
With this out of the way the renderer can now be switched to the core profile.

8cd9775513 - fixed VP8 video player. 
Also do the color space conversion on the CPU to avoid the shader hassle, performance wise it is utterly irrelevant here.

2e06ccfec6 - draw the screen overlays using the vertex buffer. 2020-01-18 16:14:30 +01:00
Christoph Oelckers
55dab6d3d3 - hooked up the high color texture colorization code. 
Not tested and probably still not working correctly, the entire feature was a nearly impenetrable mess of convoluted code. This definitely needs verification with multiple mods using it.
 2020-01-11 22:18:06 +01:00

2dc0de5824 - fixed incorrect sampler binding. 2020-01-05 17:37:28 +01:00
Christoph Oelckers
9e7f91b5ac - fixed size of texture arrays. 
We need 6 slots, not 5.
