Christoph Oelckers 16bad04da8 - premap stuff. 
# Conflicts:
#	source/glbackend/glbackend.cpp
 2020-06-22 00:06:51 +02:00
Christoph Oelckers 83a760874b - removed some Build related includes from core code. 2020-06-20 18:01:02 +02:00
Christoph Oelckers 95b4340eec - initial palette shader work. 2020-06-17 12:26:01 +02:00
Christoph Oelckers b753ea5db7 - preparations for passing palette lookup textures through the low level texture code. 2020-06-17 12:26:01 +02:00
Christoph Oelckers d4b32bf79f - fully synchronized the backend code with GZDoom. 
The camera texture code couldn't be done earlier.
 2020-06-14 21:13:22 +02:00
Christoph Oelckers 5effc95ae1 - updated startup dialog and fixed multisampling not active in the 3D scene. 2020-06-14 20:59:26 +02:00
Christoph Oelckers 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.
 2020-06-12 22:32:49 +02:00
Christoph Oelckers 9b03537f3a - fixed shadows in Shadow Warrior. 
They use a shade of 127 which wasn't clamped to a valid range in the backend.
 2020-06-12 21:40:49 +02:00
Christoph Oelckers 60b18c7ec9 - Blood: use the 2D drawer to clear the screen for 2D display. 2020-06-12 20:31:23 +02:00
Christoph Oelckers 6a9f1e9da1 - removed the old OpenGL interface. 2020-06-12 00:25:52 +02:00
Christoph Oelckers ba397f5ca1 - always draw floors opaque 2020-06-11 23:55:23 +02:00
Christoph Oelckers 22aad4999c - use the engine backend to render the scene 2020-06-11 22:26:46 +02:00
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 4c6abe1bb9 - pass the shade through the 2D drawer, so that palette emulation can still use it. 2020-06-07 14:50:12 +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 60d7f4f7c2 - got rid of the RF_NPOTEmulation flag. 
This can easily be controlled with the 2 main variables alone.
 2020-06-07 09:30:55 +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.
 2020-06-05 19:06:31 +02:00
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 40f085adea - draw fullscreen blends with the 2D drawer. 
Removing one special case of render setup. Now all 2D content is done by the same code.
 2020-06-04 18:54:10 +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 7638ead1c8 - simplified the texture sampler setup. 
DAMETH_CLAMPED was redundant and only causig problems.
 2020-06-02 16:55:02 +02:00
Christoph Oelckers 350acd2ac3 - scale the vertex coordinates that get output to the hardware by 1024. 
This is needed to get a coordinate system that is compatible with GZDoom's so that its lighting code can be reused more easily.
 2020-06-01 09:55:28 +02:00
Christoph Oelckers 783dff41b6 - fixed clamp mode setup. 2020-05-31 23:08:56 +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 2841154683 - moved code around, got a few more utilities from GZDoom. 2020-05-31 10:37:19 +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 88eea8269a - set proper palette for null translation. 2020-05-30 22:35:21 +02:00
Christoph Oelckers 82eb807090 - activate the texture layers if needed. 2020-05-30 22:27:59 +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 cca4fc609f - texture code cleanup, mainly cppying layer data into the textures at startup to be able to use a real material system. 2020-05-29 23:33:26 +02:00
Christoph Oelckers 2c94b2bb6d - split texture selection from binding. 2020-05-29 21:53:28 +02:00
Christoph Oelckers 1bc744b77b - moved hictinting data into the lookup tables. 2020-05-29 20:15:42 +02:00
Christoph Oelckers 594ec6626c - transitioned to using GZDoom's texture creation code. 
Also added support for creating indexed textures directly into CreateTexBuffer, where this functionality can be shared.
As an added plus, brightmaps are working again, this time with less hackery.
 2020-05-29 19:21:18 +02:00
Christoph Oelckers 66809ca9f4 - fixed indexed display of 2D content. 2020-05-29 16:46:36 +02:00
Christoph Oelckers 87a87c155d - moved to GZDoom's gl_hwtexture.cpp. 2020-05-29 01:03:01 +02:00
Christoph Oelckers 381e53017d - some hackery to make the camera textures in DN3D work again. 
They depend on a deleted texture not writing to the depth buffer, but other parts in the engine like ROR surfaces depend on them writing a proper depth buffer value, so for now there is a global variable that allows to exclude a single tile from ever getting rendered.
 2020-05-29 00:44:13 +02:00
Christoph Oelckers 72889540a5 - use GZDoom's gl_samplers.cpp 2020-05-28 23:48:50 +02:00
Christoph Oelckers 362be65060 - removed FHardwareTexture's mSampler member. 
This was a mostly unused relic of early development, the few places using it were static sampler settings.
 2020-05-28 21:45:33 +02:00
Christoph Oelckers 4ebe67ba3d - never render the null texture. 
Blood's ROR effects won't work if this is not done.
 2020-05-27 22:54:39 +02:00
Christoph Oelckers 193b940eef - palette code cleanup. 2020-05-27 22:19:02 +02:00
Christoph Oelckers c4017de12f - updated to GZDoom's new texture management system. 2020-05-25 23:59:07 +02:00
Christoph Oelckers 55a3c62b59 - use GZDoom's 2D drawer. 
Console and menu font colors are not ok yet, aside from that it works.
 2020-05-25 17:11:32 +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 4178d48fb6 - re-enabled GPalette and disabled brightmaps. 
In order to finish this I need the switchover, but brightmaps need an update of the texture code which requires merging a few more WIP changes before the code can be fixed.
 2020-05-25 00:31:55 +02:00
Christoph Oelckers 6bd4f77c5b - fix compilation. 2020-05-25 00:31:55 +02:00
Christoph Oelckers 72c323cf32 - disabled switch to GPalette because it's not working right yet. 2020-05-25 00:05:26 +02:00
Christoph Oelckers 531c68edfe - use GZDoom's font code to fix the crash issues and moved around some files in the PK3. 
This pulls in a lot of Doom specific font setup, this can be sorted out later as it won't get into the way.

 2020-05-24 22:53:14 +02:00
Christoph Oelckers 7a84887fc4 - transitioned FTexture. 
Mostly working. Note: Brightmaps must be per-translation!
 2020-05-24 19:12:22 +02:00
Christoph Oelckers e985db3d08 - added GZDoom's texture manager. 
It doesn't do anything yet, but it can now be used to manage textures.
 2020-05-24 16:11:10 +02:00
Christoph Oelckers d6786cf0eb - final cleanup of picanm code. 2020-05-24 13:53:27 +02:00
Christoph Oelckers db4850a028 - added a reverse tile map so that the tile manager can retrieve special info even when a tile texture is passed by object to the render code and not by index. 2020-05-24 10:30:09 +02:00
Christoph Oelckers 0c029750b6 - moved hightile replacements out of the texture class. 2020-05-24 08:47:45 +02:00
Christoph Oelckers 00e7b2fa25 - simple stuff from the texture manager inclusion commit. 
To get this out of the way first...
 2020-05-24 00:27:24 +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 f64bdccaca - moved renderstyle to 'common' and use GZDoom's color table code unaltered. 
# Conflicts:
#	source/CMakeLists.txt
#	source/common/engine/serializer.h
 2020-05-23 22:43:05 +02:00
Christoph Oelckers f929419a0a - refactoring of the lookup tables. 2020-05-23 22:43:04 +02:00
Christoph Oelckers b971bc2717 - avoid using global palette settings when drawing 2D content with a custom palette. 
Instead pass the palette info with the render call to avoid stale global state.
 2020-05-23 22:43:01 +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 621a9338e5 - render camera textures with the hardware renderer. 
This removes the last active use case for the software renderer and allows rendering the camera views at a higher resolution.
For Shadow Warrior this necessitated a split of JS_DrawMirrors, because it processed cameras and mirrors in the same loop which cannot be done with the hardware renderer.
 2020-03-29 14:01:46 +02:00
Christoph Oelckers 7533fbaa8e - fixed: special 2D palettes do not have brightmaps so any such texture must be completely excluded from being checked. 2020-02-26 18:10:06 +01:00
Christoph Oelckers 6282062492 - fixed brightmaps. 
They are no longer run through the texture postprocessor and the shader now applies them correctly.
 2020-02-18 20:43:16 +01:00
Christoph Oelckers 286d53d3bf - added the missing handling for the basepal tinting. 2020-02-11 20:55:47 +01:00
Christoph Oelckers c53d9cfc3a - reworked voxel texture generation to use the backend's palette manager. 
The original code was not able to handle changing palettes and only worked if each palette change resulted in a full texture flush - which Raze does not perform.
 2020-02-09 20:14:26 +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 dbc958baeb - fixed swapped color channels in the tinting part of the shader. 2020-02-05 20:02:50 +01:00
Christoph Oelckers 5d4514060b - disable palette emulation for Blood's cutscenes. 
These use color 255 as a valid index which the palette emulation shader does not handle.
 2020-02-04 20:40:10 +01:00
Christoph Oelckers 7bbbe63bd9 - fixed: hictint must not be enabled if the flags are 0. 2020-02-04 20:19:26 +01:00
Christoph Oelckers ab3811bac0 - fixed: The 2D drawer must apply the render state before it finishes. 
Otherwise the global state settings will not be reset.
 2020-01-31 22:07:51 +01:00
Christoph Oelckers 245aa5d3bc - reworked global palette state for robustness. 2020-01-26 10:58:00 +01:00
Christoph Oelckers be0242e919 - use correct indices for the palette tester CVARs. 2020-01-25 19:10:05 +01:00
Christoph Oelckers 99c4b6b6d7 - don't let environmental palettes (like underwater) affect the HUD and menu. 2020-01-25 18:48:48 +01:00
Christoph Oelckers 6f39b87d5b - actually draw the fullscreen blends. 2020-01-19 23:49:53 +01:00
Christoph Oelckers b066f725d4 - clear the matrix list after rendering the 2D content. 2020-01-19 23:27:59 +01:00
Christoph Oelckers aa1361acbb - make palfadedelta explicitly unsigned 2020-01-19 23:18:38 +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 352c099b5a - basics for hardware rendered camera textures. 2020-01-19 08:40:03 +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 2bc1708870 - removed the complete crosshair color hackery. 
The code needs to be refactored anyway to allow better crosshair control but this also seemed to affect global render state, considering how poorly it was all implemented.
 2020-01-18 16:14:31 +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
