Christoph Oelckers dc60c7f72e - fixed use of brightmaps.
Due to the blending they are essentially inactive on translucent content and Duke Nukem heavily abuses this.

Christoph Oelckers 5fc81d1bd4 - made brightmaps operational.
The logic is not yet optimal but at least it works.

Christoph Oelckers cae710bd59 - fixed alpha threshold.
Not only is this a deprecated feature - it also does not work right when complex lighting is at play, it must be done in the shader to get proper results.

Christoph Oelckers 0f74a5c3a4 - make the ImGui popup close on request. 2019-11-09 14:05:52 +01:00

- Dear ImGUI test.

Christoph Oelckers b6a3a60251 - console output is functional. 2019-11-06 23:40:10 +01:00
Christoph Oelckers de829128ea - hooked up the 2D drawer
compiles but not tested yet.

Christoph Oelckers 1ee4efebb0 - fixed compilation. 2019-11-04 17:58:18 +01:00
Christoph Oelckers 1e0d49f947 - game starts again. 2019-10-26 13:16:32 +02:00
Christoph Oelckers 5cf5c74695 - let kopenFileReader have a look into demolition.pk3 if nothing else is found.
This should help as long as the old resource management is still in place.

Christoph Oelckers 85d377647a - tweaked the fade ramp a bit.
For Duke Nukem and its direct offspring (Nam, WW2GI and Redneck Rampage) the ramp is not a linear fade from 0 to 1, it needs to be a little darker than that.
Unfortunately the proper factor needed here must be set manually, this cannot really be calculated from the lookup tables.

Christoph Oelckers 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.

Christoph Oelckers 39e32d560c - fixed progdir setup. 2019-10-19 19:22:23 +02:00
Christoph Oelckers 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.
2019-10-19 18:14:13 +02:00
Christoph Oelckers cd7bbe35a8 - removed all legacy fog code. 2019-10-19 15:52:46 +02:00
Christoph Oelckers 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.
2019-10-19 10:40:47 +02:00
Christoph Oelckers dab7c43f7c - fixed all compiler errors.
It mostly works again, but still has a few glitches.
2019-10-18 19:06:57 +02:00
Christoph Oelckers 23265ad213 - rework of texture management for models
Voxels yet to do.
This also removes the redundant texture matrix for the glow texture.
2019-10-18 14:04:32 +02:00
Christoph Oelckers 3da49ad20a - safety commit: all relevant code for the texturing system has been moved to texcache.cpp. 2019-10-17 21:44:34 +02:00
Christoph Oelckers 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.

Christoph Oelckers 304a906aa7 copy code 2019-10-17 14:21:51 +02:00
Christoph Oelckers 4f8e0dd936 - cleaned up a few copyright notices and unified licenses 2019-10-17 09:42:11 +02:00
Christoph Oelckers 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.
2019-10-10 23:14:57 +02:00
Christoph Oelckers 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.
2019-10-10 21:05:10 +02:00
Christoph Oelckers 1407c18f8b - cleaned out some remains of the non-indexed render path.
All of this will be redone in the backend.
2019-10-10 19:40:33 +02:00
Christoph Oelckers c428e367a0 - hotfix for texture filter settings.
This needs to be done differently later to choose the proper clamp setting.
2019-10-10 19:16:27 +02:00
Christoph Oelckers 1fee7a5f01 - cleanup of texture creation code.
There were several mostly pointless options complicating all of this.
2019-10-10 00:07:45 +02:00
Christoph Oelckers 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.
2019-10-08 01:08:08 +02:00
Christoph Oelckers dfaa162bb2 - finished the palswap handling in the palette manager. 2019-10-07 22:11:09 +02:00
Christoph Oelckers 7713860b63 wip. 2019-10-07 00:14:16 +02:00
Christoph Oelckers 734d8b7d1e - moved the palette management into the backend. 2019-10-06 21:15:53 +02:00
Christoph Oelckers 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.
2019-10-06 12:42:35 +02:00
Christoph Oelckers 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.
2019-10-06 10:19:51 +02:00
Christoph Oelckers 3fb5154dc9 - make it work again. 2019-10-05 14:17:59 +02:00
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.
2019-10-05 13:38:02 +02:00
Christoph Oelckers 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 ae1e090716 - all non-shader related GL calls are gone from the main code base. 2019-10-04 21:13:04 +02:00
Christoph Oelckers f992aebf33 - two more 2019-10-04 19:17:55 +02:00
Christoph Oelckers cb80e877ff - refactored fog and depth func setting into GLInterface. 2019-10-04 18:44:16 +02:00
Christoph Oelckers 204abab724 glColor calls refactored. 2019-10-04 18:25:18 +02:00
Christoph Oelckers 96c0c3197c - abstracted away more OpenGL calls, in particular all matrix access. 2019-10-04 18:12:03 +02:00
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.
2019-09-23 23:33:59 +02:00
Christoph Oelckers e0f823a492 - refactored texture setup to use an intermediate layer. 2019-09-18 22:16:15 +02:00
Christoph Oelckers b1763a8f4a - hooked up the texture management.
Not in active use yet!
