ac80ffcc00 - fixed scissor calculations in 2D drawer. 2016-08-15 08:53:49 +02:00
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
Magnus Norddahl

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.

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.

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.

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
Magnus Norddahl
d4615861ae Fix missing FGLRenderBuffers::IsEnabled checks 2016-08-07 00:41:17 +02:00
Christoph Oelckers
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.

7b99c883e1 - use the exact same semantics and methods to handle player visibility as in the software renderer.
This fixes invisible player sprites in recursive line portals.

Christoph Oelckers
92e2ce2aef - adjustments for weapon rendering in GL.
This adds support for the new weapon state code and fixed some lighting calculations.
Note that this currently will not allow combination of HUD models with other sprite frames yet.

99bfc64af6 - another failed attempt to use GL_CLIP_PLANE. Leave it in because it's closer to what is needed than the old code. 2016-05-12 23:41:06 +02:00

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.

066d5c63e2 - better be safe and not call GL_CLIP_DISTANCE functions on old hardware. 2016-04-26 21:55:17 +02:00
Christoph Oelckers
6e1b21d513 - added back sprite splitting for low end, plus some dynamic light code. 2016-04-26 21:31:24 +02:00
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.
- cleaned up gl_interface and removed gl.compatibility.

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

45526c2769 - basics for using hardware clip planes to split translucent stuff by 3D floor planes. 2015-04-05 18:55:21 +02:00
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.
2014-11-27 12:26:52 +01:00
Christoph Oelckers
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.
2014-10-05 09:40:36 +02:00
Christoph Oelckers
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
Christoph Oelckers
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
Christoph Oelckers
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.
2014-08-22 23:50:38 +02:00
Christoph Oelckers
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.
2014-08-19 14:18:21 +02:00
Christoph Oelckers
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.
2014-07-30 23:13:16 +02:00
Christoph Oelckers
c1d8f235c2 - renamed some stuff that clashed with gl function names. 2014-07-27 12:33:54 +02:00
Christoph Oelckers
bdf5bbd34e - make the shader timer part of the render state. 2014-07-26 20:56:10 +02:00
Christoph Oelckers
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.
