Christoph Oelckers 17e1e4175e - switched NPOT emulation to the renamed uniforms. 
This was the last feature that needed to be mapped to a GZDoom compatible render state
 2020-06-08 08:16:50 +02:00
Christoph Oelckers a6545788a6 - do RR's lightning flash as a postprocessing effect. 2020-06-07 22:06:47 +02:00
Christoph Oelckers d7225c1965 - backend update from GZDoom 2020-06-07 15:02:54 +02:00
Christoph Oelckers 9fc5f2d2e7 - some shader cleanup. 
I think it's now as close to GZDoom's backend interface as it can be without disabling needed features.
 2020-06-07 10:15:31 +02:00
Christoph Oelckers 353e3eb1fa - fixed RRRA E2L1 fog. 2020-06-07 08:24:12 +02:00
Christoph Oelckers 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.
 2020-06-05 23:18:21 +02:00
Christoph Oelckers 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.

Christoph Oelckers 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
Christoph Oelckers 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
Christoph Oelckers 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.
 2020-06-04 18:46:44 +02:00
Christoph Oelckers 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.
 2020-05-31 10:53:11 +02:00
Christoph Oelckers 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:
#	source/core/rendering/v_video.cpp
 2020-05-31 09:18:43 +02:00
Christoph Oelckers edb2cb31ee - backend update with GZDoom model code. 2020-05-31 08:55:00 +02:00
Christoph Oelckers 5728241c1c - updated backend from GZDoom. 2020-05-30 23:10:17 +02:00
Christoph Oelckers 58c62e071c - use FMaterial. 2020-05-30 22:20:06 +02:00
Christoph Oelckers 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
Christoph Oelckers 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.
 2020-05-25 00:31:55 +02:00
Christoph Oelckers 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.
 2020-05-23 22:43:06 +02:00
Christoph Oelckers 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
Christoph Oelckers 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.
 2020-03-29 15:22:07 +02:00
Christoph Oelckers 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.
 2020-02-06 18:44:06 +01:00
Christoph Oelckers 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.
 2020-01-19 16:07:09 +01:00
Christoph Oelckers 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.
 2020-01-19 14:08:48 +01:00
Christoph Oelckers 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.
 2020-01-18 22:41:08 +01:00
Christoph Oelckers 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.
 2020-01-18 16:14:30 +01:00
Christoph Oelckers 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
Christoph Oelckers 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.
 2020-01-05 12:56:32 +01:00
Christoph Oelckers 6c6874cb0e - fixed scissoring with out of range coordinates. 
Blood's status bar sets such a bogus clipping rectangle.
 2020-01-05 10:21:34 +01:00
Christoph Oelckers e84acb7e2f - invalidate the render state after finishing a frame. 
Last bound textures in particular may not be valid anymore in the next frame in movie playback.
 2020-01-05 09:38:44 +01:00
Christoph Oelckers e61e77fb82 - handle textures in the render state. 
This should complete the transition and allow storing the render state in an array so that Polymost can be rewritten to create draw lists instead of actually doing the rendering itself.

Magnus Norddahl 0714155e3a Fix ssao no longer working 2020-01-04 09:54:47 +01:00
Christoph Oelckers d4b32c535a - moved matrices to render state. 2020-01-03 23:38:50 +01:00
Magnus Norddahl 13a7b7d4b2 Hook up gl_ssao 2020-01-03 18:34:43 +01:00
Christoph Oelckers 6ba04e7a09 - fixed voxel rendering in indexed color mode. 2020-01-03 18:30:00 +01:00
Christoph Oelckers f743b22661 - render voxels as triangles instead of quads. 
Quads are not available in the core profile which is required to run GL 3.3 on macOS.
