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.

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.

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.

ce75832945 - color and depth func moved to render state. 2020-01-03 11:43:44 +01:00
Christoph Oelckers
27ed6cdae5 - viewport and scissor moved to render state. 2020-01-03 10:48:22 +01:00
Christoph Oelckers
cfc0ba48cb - moved render style handling to the render state and simplified its storage to use FRenderStyle instead of its components. 2020-01-03 10:48:22 +01:00
Christoph Oelckers
3380420de9 - converted the clear screen commands. 2020-01-02 23:56:35 +01:00
Christoph Oelckers
3608a646e6 - converted the simple state settings into renderstate flags. 2020-01-02 23:34:21 +01:00

6156e7382a - preparation for moving GL state into the renderstate struct. 2020-01-02 23:15:16 +01:00
Christoph Oelckers
afb1d7b885 - changed a few licenses of my own code to something more permissive. 2020-01-02 19:38:47 +01:00
Christoph Oelckers
7ec8368688 - used the wrong formula to calculate shadeDiv. 2020-01-01 11:49:32 +01:00
Christoph Oelckers
3d47652d08 - had a look at Exhumed's shade tables and implemented the necessary adjustments for the 3 with abnormal gradients. 2019-12-31 22:53:03 +01:00
Christoph Oelckers
1890df98f9 - process lines through the 2D drawer. 2019-12-31 19:02:55 +01:00
Christoph Oelckers
964e303dd7 - draw the textures on the automap with the 2D drawer. 2019-12-31 15:05:08 +01:00
Christoph Oelckers
6b431cec2c - fixed: True color texture replacements were set up incorrectly.
They incorrectly set themselves up as their own glow and detail textures.
These layers also weren't disabled for the next texture.
2019-12-30 20:44:37 +01:00
Christoph Oelckers
ad24a1ce31 - place weapon sprites in a separate render list.
They need to be drawn in a different pass than the 2D overlay HUD so the backend must have them separately.
2019-12-30 20:16:51 +01:00
Christoph Oelckers
5830e72ab0 - fixed some rotatesprite issues:
* scissor was not applied
* texture coordinates were fetched from the wrong texture, courtesy of using global variables.
2019-12-30 19:37:23 +01:00
Christoph Oelckers
6459f4e532 - refactored rotatesprite to really use the 2D drawer.
Mostly working, except clipping and weapon sprites.
2019-12-30 19:37:23 +01:00
Christoph Oelckers
737bf15ad8 - added GZDoom's postprocessing/presentation code.
Compiles but only draws a black screen. Something must be missing but no idea yet what that might be.
2019-12-28 22:36:47 +01:00
Christoph Oelckers
a021b96119 - added the needed parts of GZDoom's render backend to have the postprocessor working.
Not hooked up yet.

68a3a60d0b - Exhumed menu tweaks - draw a background and caption for the option menus the game originally did not have.
- fixed a crash in the 2D drawer when two consecutively allocated vertex buffers had the same address. Strangely this only occured with Exhumed but not the other games
- fixed Exhumed crashing with sound disabled.

Christoph Oelckers
62e9112133 - renamed the internal resource directory to "engine" and routed most literal mentions of the engine name through version.h
All this comes from a time when I didn't use version.h so it's better to do it the same way as GZDoom to allow easy renaming of the engine.
2019-12-26 14:04:53 +01:00
Christoph Oelckers
120a985b98 - disable palette transparency for color 255 when running an animation.
There's several intro cutscenes using the full palette and for these the color must not be nulled as it should for in-game textures.
2019-12-25 14:13:15 +01:00
Christoph Oelckers
3b98635170 - removed all remaining references to SDL. The Windows version is now fully native. 2019-12-23 20:03:03 +01:00
Christoph Oelckers
62ecedf1f8 - got it to the point where it can render to the GL surface from the native backend. 2019-12-23 19:37:40 +01:00
Christoph Oelckers
a1f7f0cc30 - added the GL framebuffer class.
Everything compiles again but obviously no init code will run for now.
2019-12-23 15:40:17 +01:00
Christoph Oelckers
30cbcb54b1 - renamed the remaining file system access wrappers in cache1d.h 2019-12-07 10:31:27 +01:00
Christoph Oelckers
749eda32c5 - moved kopenfilereader into the FileSystem class. 2019-12-07 10:14:51 +01:00
Christoph Oelckers
1cfe5be130 - fixed creation of true color textures.
The palette check was not correct so they ended up empty and caused other problems down the line.
2019-12-01 21:43:54 +01:00
Christoph Oelckers
1f1e39fac0 - consolidation of texts for episode and skill menus
So far without localization capability - the engine cannot handle it yet.
2019-11-25 00:02:00 +01:00
Christoph Oelckers
b3b5ac440a - fixed Blood fullscreen tinting.
The lookup table for blend equations was missing one entry at the start. No idea why this became apparent only now.
2019-11-24 19:07:23 +01:00
Christoph Oelckers
ceb07280cf - more work on the menu.
Duke Nukem's menu title is getting rendered.
2019-11-22 22:52:11 +01:00
Christoph Oelckers
2740913c60 - added a redirection hack for rotatesprite so that it can be transitionally used in the 2D drawer. 2019-11-21 19:30:27 +01:00
Christoph Oelckers
dc60c7f72e - fixed use of brightmaps.
Due to the blending they are essentially inactive on translucent content and Duke Nukem heavily abuses this.
2019-11-15 20:51:02 +01:00
Christoph Oelckers
022c074ece - fixed brightmaps again - hopefully for real this time.
The lighting model being used here is not really good for implementing render effect.
2019-11-11 23:54:09 +01:00
Christoph Oelckers
3be9deb070 - removed the different shadeDiv for Ion Fury.
This isn't necessary and was apparently caused by a bug that got fixed in the mean time.
2019-11-11 23:24:31 +01:00
Christoph Oelckers
79561ace09 - use the precalculated or script-specified fade colors, if present. 2019-11-10 21:11:17 +01:00
Christoph Oelckers
5fc81d1bd4 - made brightmaps operational.
The logic is not yet optimal but at least it works.
2019-11-10 19:42:26 +01:00
Christoph Oelckers
21ac5e87b5 - added blend table translucency estimation instead of using a lame default.
- draw fullscreen blends below the console.
- moved all mouse event processing out of the SDL backend to D_PostEvent.
- removed all remaining code for dealing with mouse buttons directly.
2019-11-10 15:15:14 +01:00
Christoph Oelckers
87acd7fef6 - fixed blend mode for the 2D drawer. 2019-11-10 12:12:15 +01:00
Christoph Oelckers
55018aae7e - fixed mouse scaling 2019-11-10 11:59:22 +01:00
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.
2019-11-10 10:01:31 +01:00
Christoph Oelckers
7e70c217fe - fixed console event processing and added a texture memory calculator. 2019-11-09 23:58:26 +01:00

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.
2019-10-25 02:01:52 +02:00
Christoph Oelckers
20df360778 - converted the Polymost CVARs. 2019-10-23 21:11:37 +02:00

53248945e8 - added license headers. 2019-10-20 08:07:12 +02:00
Christoph Oelckers
e5ddb28a2b - renamed texcache.cpp and moved it to its proper place.
The old content no longer exists, this is entirely backend code now.
2019-10-20 08:04:54 +02:00
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.

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.
2019-10-19 23:14:36 +02:00
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.
2019-10-19 22:46:37 +02:00
Christoph Oelckers
39e32d560c - fixed progdir setup. 2019-10-19 19:22:23 +02:00
Christoph Oelckers
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
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
e2f9e12efb - implemented shade level based depth fading for the true color renderer. 2019-10-19 16:35:06 +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
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.)
2019-10-19 10:22:02 +02:00
Christoph Oelckers
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.
2019-10-18 22:09:19 +02:00
Christoph Oelckers
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.
2019-10-18 14:04:32 +02:00
Christoph Oelckers
542994cc20 - added lookup for brightmap palettes. 2019-10-18 12:11:53 +02:00
Christoph Oelckers
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.

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.

0aa5db7969 - project rework to shorten compile times.
* subprojects fpr game frontends added and unsigned char option put into global flags.
2019-10-16 23:09:02 +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

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

Christoph Oelckers
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.

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.
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
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.
2019-10-06 09:31:36 +02:00
Christoph Oelckers
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.
2019-10-05 21:59:03 +02:00
