9437387b4a - fixed handling of FogDisabled flag 2019-10-20 00:45:47 +02:00
Christoph Oelckers
bb4a19cf3a - added a few more texture formats to FHardwareTexture.
For brightmaps we do not need full RGBA8 data with mipmaps - RGBA2 without mipmaps is fully sufficient here and will save a lot of video memory.

7d2f61db2e - converted all boolean parameters of the shader into a single flag word.
- discarded the idea of transient palettes because the maintenance here stood in no relation to the savingd.

d4fc13fba5 - cleaned up the sampler manager's content names and added the missing types to allow easier switching between indexed (no filtering) and non-indexed (filter as per user option). 2019-10-19 19:10:09 +02:00

2152780806 - added some hackery to render voxels properly again.
Something about their data preparation is not right, their depth looks totally off and causes fog to become to dense.
One more reason to reconstruct the renderer in a sane fashion.

e2f9e12efb - implemented shade level based depth fading for the true color renderer. 2019-10-19 16:35:06 +02:00

4a9f0248d7 - removed the texture ID cache.
Although this initially helped, it was only because it partially covered up the issues from the real problem which was using the sampler properties of the texture offsets.
With that one fixed this cache became pointless.

bc986b8054 - make the engine consistently use BGRA data - the internal palettes were still RGBA, which caused problems down the line.
- increased cache size to 200 MB (Note: The cache really needs to be replaced with something better that can adapt better to a system's RAM size.)

00d59459a1 - fixed creation of true color textures and disabled fog in palette mode.
The fog should go away entirely but in palette mode it made everything too dark.

dab7c43f7c - fixed all compiler errors.
It mostly works again, but still has a few glitches.

23265ad213 - rework of texture management for models
Voxels yet to do.
This also removes the redundant texture matrix for the glow texture.

542994cc20 - added lookup for brightmap palettes. 2019-10-18 12:11:53 +02:00

530a9944f7 - texture loader redone but not tested yet
Models are currently non-functional and need to reroute their texture handling to the global texture manager instead of handling everything themselves.

Voxels also need a bit of work to make their texture management more automated.

bef8c9ae76 - hictinting cleanup.
This needs to be moved into the backend, and partially into the shader. So far this only removes the code from the main rendering logic, the final implementation is not done yet.
It had to go because it required the main rendering code to look deep into the texture data which would be a major blocker for refactoring.

0aa5db7969 - project rework to shorten compile times.
* subprojects fpr game frontends added and unsigned char option put into global flags.

c588cd499a - let GLInstance::Draw set the palette indexing mode.
This can be trivially decided based on the texture type, so there's really no need to let the higher level code deal with this.

fbc7e626e9 - removed the fullbright render pass, because this is better set up as a shader option.
- also removed the legacy fog modes because their implementation did not mix well with the texture system - they are also not really useful to begin with.

The last fog mode will most likely also be removed once true color shading is working but that one is less of an issue.

1407c18f8b - cleaned out some remains of the non-indexed render path.
All of this will be redone in the backend.

c428e367a0 - hotfix for texture filter settings.
This needs to be done differently later to choose the proper clamp setting.

1fee7a5f01 - cleanup of texture creation code.
There were several mostly pointless options complicating all of this.

7131fe6c6e - use separate textures for the palswap shade tables.
This creates a lot less mess than one big texture and also allows easier use of texelFetch in the server which is preferable for data textures.

ef2de97077 - the harmless changes of the failed refactoring of the shader. 2019-10-06 19:32:35 +02:00
Christoph Oelckers
cf30f5560b - upgraded the polymost fragment shader to GLSL 3.3 as well, removing all legacy features from it.
The only compatibility mode feature left is the main drawer function using glBegin/glEnd but changing that is not as urgent as the rest.
This also cleans up the fog application and adds the exponential fog mode again that somehow got lost over time.

3d538b4c8f - use explicit vertex attributes for everything.
No more glVertex, glTexCoord or glColor calls anywhere.
2019-10-06 10:46:23 +02:00
Christoph Oelckers
71d132b470 - use explicitly declared matrix uniforms.
The builtin matrices are no longer available in modern GLSL, preventing an upgrade of the shader.
Also perform better reporting of shader compilation errors.

126f670239 - draft class for in-game textures.
These will abstract away all the gory details so that the using code only sees a single entity to use.

93ad83b380 - use GZDoom's texture backend to read hightile textures. (Hightile tinting code moved to the shader but isn't active yet.
- remove all code for faking gamma correction through palette manipulated images.

Christoph Oelckers
3c193bb243 - moved the animvpx shader to the backend code.
This removes the final access to OpenGL from the rest of the source, with the exception of the glFinish call in the swap code.

b83349fe6b - moved the surface shader to the backend and the shader source to the resource file. 2019-10-05 13:09:15 +02:00
Christoph Oelckers
bd4e4834e3 - moved the main shader and its entire uniform maintenance into the backend. 2019-10-05 12:28:08 +02:00
Christoph Oelckers
d058084c10 - added an engine resource file.
Currently this only contains the main Polymost shaders and the resources from nblood.pk3.
The latter cannot be used yet because the Build resource management system is too stubborn to add the newly added file without some changes.
It's better to refactor the entire system instead.

Christoph Oelckers
ad4527c8be - initialize the GL backend in the proper place.
As long as there are still video mode switches this needs to be in the video mode switching function.

d63cf04e06 - removed the compressed texture cache.
This is a pointless relic from the past and makes zero sense with modern graphics hardware.

6536d910b3 - all drawing is being routed through the interface layer, all vertex buffers are gone.
No big loss here, none of them made much sense performance wise.

318009fd69 - added a centralized drawer and converted the main geometry drawer to use it. 2019-09-16 19:35:04 +02:00
