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.

9a7f9bdb4c - moved postprocessing shader classes to hwrenderer after removing all dependencies on OpenGL. 2018-06-13 22:37:01 +02:00

3401876476 - use FShaderProgram through an abstract interface and remove all dependencies on the GL renderer from the shader definition source files. 2018-06-13 22:08:55 +02:00

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

59827cd601 - use layout binding qualifiers on uniform buffers when GLSL version >= 4.2 
This has no performance benefits but allows checking shader generation correctness without having to implement Vulkan first.

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.

b8b5802599 Added a uniform buffer abstraction class 
May get some more methods later, this is just a start to get going.

8486cd2c0e - fixed generation of brightmaps for sprites. 
This forgot to take the added empty border for filtering improvement into account.

2d50f535ff - fixed and simplified the vertex counter for wall polygons. 
This is now allowed to overestimate the number of vertices to reduce computation time for a rarely occuring special case that was eating most of the time and was causing errors with some walls.

496e6e2e8f - fixed: The vertex height updater was using the index buffer offsets to access the vertex buffer. 
I missed this part when repurposing the vboindex members to store the index buffer offsets.
However, since both indices are needed, they need another set of variables.

226e8f84da - most of gl_bsp.cpp moved to HWDrawInfo. 
Only the vertex buffer update check needs to be done yet.

df0b1e8dae - moved the clipper out of GLSceneDrawer and let it be handled by HWDrawInfo. 
The precise way the clipper needs to be maintained may differ between APIs, so it is no longer owned by any render structure but instead HWDrawInfo only contains a reference.
For OpenGL there is still only one static clipper because without multithreaded BSP traversal there is no need for more.

5f87e81b6a - moved CurrentMapSections and in_area from GLSceneDrawer to HWDrawInfo. 
Not only are they better placed in the common code, but they are also both per-viewpoint and not per-scene, so this is a far more suitable place and avoids saving and restoring them in the portal code.

31abe3df7e - avoid reusing the same mVBuf pointer for the different renderers as that causes too many problems when switching between them 
- remove gl_ prefix for model functions that are no longer GL specific

3e204080ae - render sector planes in one draw call. 
On a fast and modern graphics card this is a lot faster than doing it per subsector but it may not be without drawbacks on older hardware so it will require some testing on older hardware.
For me Frozen Time's view over the bridge went from 46 fps to 51 fps with this change, the time saved was roughly 2 ms.

2125f8b9d1 - use triangles instead of triangle fans to render flats. 2018-05-19 14:42:25 +02:00
Christoph Oelckers
fd3681dae2 - use an indexed vertex buffer to render the flats. 
Right now this has no advantage but it allows optimizing the data, e.g. rendering an entire sector in one go instead of per subsector.

1656bbf9ec - route the BlurScene call in the menu through DFrameBuffer. 
Game code should never ever call the renderer directly. This must be done through the video interface so that it can also work with other framebuffers later.

e1ad4b618d - fixed: The targeter drawer did not check the return value of its setup function. 
This caused invalid items to be passed to the renderer.

099057b142 - moved the vertex and light data generation back to the render pass for modern OpenGL with persistently mapped buffers. 
Having this extra CPU time in there allows for better parallelization with the graphics driver and GPU.

52d73eabbf - weapon drawing code refactor complete. 
Setup and drawing are now done separately, this also no longer needs the Quad drawer.
