491898fe2c - fixed calculation of projection matrix for weapon sprites. 
- fixed color mask for green/magenta.
- fixed crash when initializing video, because it was accessing 'screen' before it was set from within the framebuffer's constructor.

c3d5b960ee - refactored the entire Stereo3D system to get rid of the class hierarchy and all its ugly implications. 
Ultimately all this needs is a small data table describing the geometric properties of each mode and a single Present function that calls the mode specific variants.
Code size got reduced from 50kb to less than 20kb with proper separation of the generic parts from the OpenGL parts.

1cf3af9c41 - moved the current portal pointer to HWDrawInfo so that the portal managed does not need to save and restore a global variable for each portal. 2018-06-23 13:51:19 +02:00

7f5272c23f Deleted GLSceneDrawer 
Since it didn't contain any data anymore it was relatively pointless. Code has been moved to FDrawInfo and GLRenderer, depending on its scope.

54970b60e8 - use locally stored viewpoint variables in the hardware renderer. 
- move a few variables from SceneDrawer to FRenderViewpoint.

The global r_viewpoint variable is left alone now to always represent the current viewpoint to the play code.
The main reason behind this change is to reduce the amount of global variables being used by the hardware renderer's scene processing code.

b4351e538f - fix weapon missing when bloom was off (scene was already copied to post processing, but nothing had bound the PP frame buffer) 2018-06-17 01:45:20 +02:00

4937848123 - refactoring of fixed colormap stuff to have it better organized and to reduce the number of uniforms in the main shader. 
This removes 3 uniforms, consisting of 9 floats. Those were merged into other values that never get used at the same time.
It also moves the costly setup of the fixed colormap out of the render state into the 2D processing code.
Since 3D forces use of render buffers now, it is no longer necessary to draw the entire scene with the colormap active, meaning it can be handled more efficiently.

9ff7e5a4ef - force render buffers to be active. 
For modern hardware the fallback path really makes no sense and this allows to simplify some things quite a bit.

612fb40f3a - don't use uniforms related to fixed colormaps for other things. 
The fixed colormap is a per-scene global setting that normally does not need to change ever during rendering of a scene so it's easily shoved aside into a static uniform buffer.
Having to change this buffer for inconsequential stuff should be avoided, especially when there's other uniforms that are just as good to hold these values.

9a7f9bdb4c - moved postprocessing shader classes to hwrenderer after removing all dependencies on OpenGL. 2018-06-13 22:37:01 +02:00
Christoph Oelckers
8bf009bd89 - added a RenderQueue parameter to all Bind functions of the postprocessing shaders. This is unused for now. All places calling these pass a dummy NOQUEUE value which is just a nullptr. 
This is for Vulkan preparation where all of this needs to run in a user-specified context so that this code can be moved out of the GL folder without depending on OpenGL's global state model.

ce50b0e46b - read sampler bindings from the shader instead of tagging along a large amount of support data. 
Works for most shaders, except SSAO.

f166624eb2 - some fixes to the PP shader interface. 
The binding point needs to be part of the ShaderUniforms class because Vulkan will need this value to generate the declaration in the shader source.
There's still one issue here: Since OpenGL has no local render state, the buffer must be bound every time it is used. Once the code is better abstracted this should be moved to a higher level class that knows all associated data and how to set it up.
