3455610031 - base palette cleanup. 
Avoid passing this anywhere in the client code. It should only be set right before rendering the 3D view and the only code using the base palette should be the 3D renderer and hud_drawsprite.
Also make the palette override CVARs 3D view only in debug mode.

efb73d04a0 - re-fixed the fix: Turned out that flipped offsetting is a bit more tricky. 
Due to how this works it cannot be done automatically, it must be passed as a parameter because at the point where the offset gets applied, all information about how it was specified is lost.
This must be enabled as a specific parameter to DrawTexture.

dae1506182 - change std::max() to std::min() in glbackend.h. Fixes issue in coelckers/Raze#83. 2020-07-05 09:05:19 +02:00

30300bf3b2 - allow shade in glbackend.h to accept negative values, but still at a max of numshades-1. 
* This fixes some issues with distance lighting issues in Duke3D as reported at https://forum.zdoom.org/viewtopic.php?f=341&t=68838&start=75#p1158417.

bb57590d34 - add gl_texture CVAR to glbackend à la GZDoom. 
* Will be useful for further debugging of the lighting to determine whether Build actually did/does do different visibility for floor/walls/ceilings, etc.
* Idea inspired by Gez: https://forum.zdoom.org/viewtopic.php?f=341&t=68838&start=75#p1158294

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.

9b03537f3a - fixed shadows in Shadow Warrior. 
They use a shade of 127 which wasn't clamped to a valid range in the backend.

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

4c6abe1bb9 - pass the shade through the 2D drawer, so that palette emulation can still use it. 2020-06-07 14:50:12 +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.

60d7f4f7c2 - got rid of the RF_NPOTEmulation flag. 
This can easily be controlled with the 2 main variables alone.

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.

d812c2997c - start renaming uniforms to match GZDoom. 
Needed to allow using the same shader with the backend.

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.

cf6855904d - took projection and view matrix out of the render state. 
This is a preparation to migrate to GZDoom's HWViewpointUniforms buffer.

7638ead1c8 - simplified the texture sampler setup. 
DAMETH_CLAMPED was redundant and only causig problems.

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.
