589936f570 - draw the colormap blend after postprocessing, not before it. 
- added colormap shader to postprocessing.

This replaces the in-place application of fullscreen colormaps if renderbuffers are active. This way the fully composed scene gets inverted, not each element on its own which is highly problematic for additively blended things.

3389a5a74e - removed most of the specific options for legacy hardware and consolidated them in one variable (does not work yet.) 2016-09-01 11:52:52 +02:00

8f535997f8 - enable core profile by default on GL 3.x. 
After doing some profiling it was very obvious that this has better performance than client arrays. Persistent buffers are still better, though, especially for handling dynamic lights.

Christoph Oelckers
0f0dc2c852 - implemented buffers for GL 3.x. These only get mapped during the data collection pass so the order of some things is different here. 2016-08-29 10:43:03 +02:00

9555617816 - fixed: The default for position.w is 1, so gl_quaddrawer.cpp needs to set this, too, for the uniform vertex positions. 2016-08-22 22:02:02 +02:00
Christoph Oelckers
250be72939 - added handling for drawing with uniform vertices. It draws something but in the wrong place. Right now I have no idea what's happening... 2016-08-22 15:31:23 +02:00
Christoph Oelckers
7ba5acfb35 - added quad drawer interface so that this part can be done without altering a vertex buffer. 
So far it's only the framework, the new code is not active yet.

Christoph Oelckers
4e8a96aa0e - removed FRenderState::set2DMode because it had no effect. This looks like development garbage from old times. 2016-08-14 09:14:26 +02:00

c817979eae Remove GetTrueHeight from GL renderer and concentrate all viewport calculations in SetOutputViewport 2016-08-14 09:05:48 +02:00
Christoph Oelckers
353a464f5b - fixed: The 2D texture drawer did not reset the render state's color so any previously set desaturation would persist. 2016-08-13 22:15:00 +02:00
Christoph Oelckers
e5f88a9883 - fixed: The textured automap was not using correct light levels. 
In order for the externally passed vertex attribute to work the buffer's color attrib array needs to be disabled for these.
 2016-08-08 16:18:07 +02:00
Christoph Oelckers
675822004d - use static buffer data and a uniform to handle the texture positioning of the present shader. 
That's again one less write access to the buffer. The uniform method was chosen because this way a buffer update can be completely avoided, and setting a single uniform is a lot cheaper and simpler to handle.
 2016-08-08 16:06:02 +02:00
Christoph Oelckers
8daaf61160 - predefine the vertex data for the blend overlay which will never change throughout the lifetime of the GLRenderer object. 2016-08-08 14:24:48 +02:00
Christoph Oelckers
9c9edbffdb - on older ATI drivers where the clip planes are broken, only disable the clip planes themselves, but not OpenGL 3.x so that dynamic lights still work as intended. 
- only disable clip planes on Windows, but not on Linux or macOS.
- If a driver reports full OpenGL 4.5 support, assume that all features are working properly.
 2016-08-08 12:55:09 +02:00
Christoph Oelckers
def3ad7533 - refactored all 2D drawing to use its own vertex buffer which does not need to be mapped permanently. 2016-08-08 12:13:09 +02:00

6a66d0255d - use a dedicated vertex buffer for rendering the wipes. 
- fixed: The postprocessing shaders clobbered the render state's vertex buffer info by bypassing and not notifying it of the change.

Christoph Oelckers
d4806f82ca - reinstated some texturing-based dynamic light code. Not active yet and not tested yet. 2016-04-28 00:58:44 +02:00
Christoph Oelckers
09f54b0940 - cleaned up the clip plane management for portals. 
Unfortunately the math behind the old clip planes is utterly impenetrable and so poorly documented that I have no idea how to set that up, so it is deactivated for now. It wasn't working anyway.

Christoph Oelckers
924b72b633 - added workarounds for the invulnerability colormap for non-shader rendering. Unlike the shader based versions these do not decolorize the screen. The advantage to the old texture duplication is that this is far less stressful on performance. 2016-04-26 20:02:57 +02:00

Christoph Oelckers
3b1500438d - got rid of VAO's. they have no impact on performance and are a general nuisance if some render paths cannot use them.

f066457a48 - add shader patching to allow running the engine with GLSL 1.2.

Christoph Oelckers
45cf65afbd - moved the aspect ratio correction factor from the projection to the view matrix where it should have been from the start. 
- removed the mCameraPos variable in FGLRenderer because it was only used in one place where it is just as easy to use the global viewx/y/z variables directly.
 2014-12-29 22:42:19 +01:00
Christoph Oelckers
ec627d94dd - fixed: The depth clamp setting needs to be tracked per portal so that it can be properly restored afterward. 
Regular skies need it off but SkyViewpoints need it on - and all others need to use the parent's setting.
So without engine side tracking we can end up rendering the sky with this setting off, resulting in omission of the fog layer.

e5cd90f323 - use separate vertex buffers per model to avoid large memory usage peaks. Also delete the geometry data for the models once it has been copied into the vertex buffer. 2014-10-24 11:43:25 +02:00
Christoph Oelckers
5302a10a7d - diable software lighting for textured automap. 
* since it is designed for software-style light diminishing it doesn't work for 2D.
* additionally it left the lighting state in an unsuitable setting for further 2D rendering.
 2014-10-23 09:19:30 +02:00
Christoph Oelckers
fd3128a164 - fixed: When changing enhanced nightvision mode the shaders need to have their fixed colormap state reset to ensure that the new settings get used. 
- fixed: The shader code for handling special fixed colormaps did not use the color vertex attribute which was most evident with the 'shadow' render style on the spectre.

4682736585 - fixed: non-tiled mid textures on a fog boundary require some special clamping to be performed in the shader. 2014-09-21 11:08:17 +02:00
Christoph Oelckers
acf6c259d8 - changed the handling of alpha textures. The only special case they need is with palette-less textures and this can be handled far more easily and robustly with a predefined translation instead of passing another parameter through all the layers of the texture management code. This also fixes problems with paletted PNGs that get used as an alpha texture because the old method clobbered the image's palette. 2014-09-09 13:21:36 +02:00

4bb320a27c - route texture binding through the renderstate class for better control. Currently it's just a direct passthrough but this will change. 2014-09-09 12:00:42 +02:00

904cc2e158 - some code cleanup. 2014-08-23 18:54:24 +02:00
Christoph Oelckers
1050013017 major cleanup of the texture manager: 
- use sampler objects to avoid creating up to 4 different system textures for one game texture just because of different clamping settings.
- avoids flushing all textures for change of texture filter mode.
- separate sprite and regular dimensions on the material level to have better control over which one gets used. It's now an explicit parameter of ValidateTexture. The main reason for this change is better handling of wall sprites which may not be subjected to such handling.
- create mipmaps based on use case, not texture type.
- allows removal of FCloneTexture hack for proper sharing of the same sprite for decals and other purposes.
- better precaching of skyboxes.

00d7707aef - allow reallocation of light buffer if more lights are needed. 
- added a light preprocessing pass to the renderer so that a non-persistent buffer can be used with minimal mapping/unmapping. This only gets used if necessary because it adds some overhead to the renderer.

a63871d170 - at least for Intel GMA we need shaders without 'discard' to render non-transparent stuff. The performance penalty is rather hefty here. 2014-08-02 21:06:34 +02:00
Christoph Oelckers
7967082e60 - use the light buffer to handle dynamic lighting. 2014-08-01 20:59:39 +02:00
Christoph Oelckers
ef8f66c9a1 - removed the code for hardware alpha testing again because it didn't work anymore with how things are set up now. 
- we need to check all GL versions when trying to get a context because some drivers only give us the version we request, leaving out newer features that are not exposed via extension.
- added some status info about uniform blocks.

eb9d2d9917 - reactivate compatibility profile so that immediate mode drawing can be used on older hardware not supporting persistently mapped buffers. 
- reactivate alpha testing per fixed function pipeline
- use the 'modern' way to define clip planes (GL_CLIP_DISTANCE). This is far more portable than the old glClipPlane method and a lot more robust than checking this in the fragment shader.

b8bcbe819b - removed texture based dynamic lighting. For GL 3.x the shader approach is always better.

00fcf4bc06 - for some reason using world coordinates for clipping in the shader is somewhat imprecise so the clip plane heights have to be adjusted a bit for it. 2014-07-13 13:25:42 +02:00
Christoph Oelckers
d868f60f6c - since the clip planes for plane mirrors did not work anymore I reimplemented them using shader based logic. It still needs to be seen if this affects performance on older hardware. 2014-07-13 12:14:12 +02:00

54297acde4 - removed obsolete gl_lightbuffer code. 
This never worked properly and by now far better options are available to solve the problem of dynamic light data uploads.

1efc2938b7 - implement model vertex buffer and draw MD2 models using it instead of using the GLCommands from the model. 2014-06-29 23:24:16 +02:00

ffcb6cb70a - added second vertex coordinate attribute for model interpolation. 2014-06-29 11:00:21 +02:00
Christoph Oelckers
2925c96b59 removed all GL 2.x code. 
After thinking about it for a day or so I believe it's the best option to remove all compatibility code because it's a major obstacle for a transition to a core profile.
 2014-06-21 15:50:32 +02:00
Christoph Oelckers
412d6499d9 - removed the voxel vertex buffer because it needs to be gone before implementing a model vertex buffer. 2014-06-19 14:46:55 +02:00
Christoph Oelckers
3644073bbd - use a software buffer for immediate mode rendering. This allows using the regular buffer code to collect data for both render modes and allows removal of a lot of duplicated code. 2014-06-15 01:14:41 +02:00
Christoph Oelckers

54425ee2ef - fixed: Desaturation factor was applied incorrectly. 
- Also fixed some very strange thing in the shader's desaturate function. For unknown reasons using the 'mix' function there did not work.
- fixed: The fog boundary special shader could not be used.

4d005bdfa0 shader rework 
All those special shaders have been merged together.
Mostly working but the non-shader lighting seems a bit broken.

b9a6fe80a4 Do not use the shader to handle STYLEF_RedIsAlpha. 
Turns out that the name doesn't accurately describe what it does.
It is correct for images that come with their own palette or are true color.
But for images using the game palette it doesn't use the red channel to determine translucency but the palette index! Ugh...

This means it cannot be done with a simple operation in the shader because it won't get a proper source image. The only solution is to create a separate texture.

c47c7421a3 - route all glColor calls through render state. 
- add sector links to dynamic lights.
 2014-05-11 22:57:42 +02:00

978ace241c - removed all code that mixes together the different lighting methods. Now everything goes through the 3 different light parameters in the render state. 
- removed cm parameter from many functions.
 2014-05-11 21:47:54 +02:00
Christoph Oelckers
887d35d559 - remove colormap from texture generation parameters. The one remaining special case, alpha texture on old hardware is now handled by the currently set texture mode at the time of use. 
- use the cleaned up decal lighting code from the first GLEW branch.
 2014-05-11 19:44:19 +02:00
Christoph Oelckers
7793bbbcc9 Further cleanup of lighting code. 
- remove thing color from lighting calculations.
- implement alpha textures and inverse sprites for infrared as texture modes. This still requires some handling for the alpha texture mode for non-shader rendering because there is no way in the fixed pipeline to do it. The inverted texture effect can be done with a texture combiner.
- fixed: ThingColor for sprites was set in the wrong place. It must be in the Process function, not in the lighting calculation.
- added functions for isolated calculation of sprites' dynlight color.

Christoph Oelckers
53f4cd0108 - added objectcolor uniform. This will be used to hold the thingcolor for shader based rendering. 2014-05-11 16:06:25 +02:00

f3a9cb0cfa remove special texture creation for fullscreen colormaps. 
On GL 3.x+ this isn't needed at all and on older hardware it causes performance issues, in particular with hires textures due to impossibility of precaching.
In addition it forces some really awkward handling of lighting for things that have their own color, like stenciled sprites or particles.

With this special case gone it will be possible to handle this case in a saner manner than it is right now.

As compensation for older hardware a fullscreen blend will be drawn over the entire screen. This won't be 100% accurate but it's preferable to keeping the current method.

Christoph Oelckers
09f4071436 Ok, it had to be done: Removed shader support for pre GLSL 1.3/GL 3.0 hardware. The compromises needed to accomodate these are just too bad and would block any attempt at streamlining the code. 2014-05-11 13:27:51 +02:00
Christoph Oelckers
7d3beb665b - rewrote vertex buffer code to require GL_ARB_BUFFER_STORAGE extension. 
This means it won't work anymore on anything that doesn't support OpenGL 4.0, but I don't think this is a problem. On older NVidia cards performance gains could not be seen and on older AMDs using the vertex buffer was even worse as long as it got mixed with immediate mode rendering.

b09405a8bd - changed rendering of glowing walls so that it doesn't require an additional vertex attribute, just pass the floor and ceiling planes as uniforms. 2014-05-10 17:09:43 +02:00

b61ef3a107 - bumped minimum supported OpenGL version to 1.4. The engine was already using several 1.3 and 1.4 features which would have caused problems on 1.2. 
- removed gl_vid_compatibility. With the bump to 1.4 no hardware requiring this flag is supported anymore.
- disabled 16 bit framebuffers for the same reason. As a conseqence all code for rendering without stencil could also be removed.
