9ef5e00cdf - some cleanup and preparation on RenderState interface. 2018-10-20 21:36:50 +02:00
Christoph Oelckers
3c3be0d349 - started with an abstract render interface, most importantly handle the stencil for plane flooding through the render state object instead of changing GL state directly. 2018-10-20 21:08:24 +02:00
Christoph Oelckers
510aa600dd - moved hw_renderstate.h to hwrenderer folder and renamed one GL constant it was using. 2018-10-20 18:37:12 +02:00

5f838d52b9 - some cleanup on the OpenGL interface and its flags.
Most importantly, the separate command line options for switching on the legacy buffer handling have been removed.
There's really no need for them anymore, because unlike in earlier versions many of the implementation differences no longer exist - with the exception of where the light and vertex buffer contents are generated.
For testing this, -glversion 3 is sufficient.

74ba142eae - allow vertex creation for sprites in the setup pass.
Currently only used by legacy hardware.

00c8c6e3b2 - generate vertices for skybox sectors in the processing pass.
Aside from the sprites this was the only other remaining use of FQuadDrawer.

e5ff500c5a - rewrote render hacks to prepare their vertex data in the processing pass.
This eliminates 3 of the 5 remaining occurences of FQuadDrawer and gets a large section of code out of the GL backend into the common hardware rendering code.

84a55667d9 - removed more old code from flat renderer.
VBOHeightCheck was from early development when interpolation was not reflected by the vertex buffer.

acb9505606 - fixed cherry-picked commit so that modern OpenGL can still do the light setup in the render pass. 2018-10-20 10:33:26 +02:00
Christoph Oelckers
a9c8546ba3 - changed dynamic light setup so that it is completely in the processing pass, not the render pass.

bc1e659c7b Revert "- reworked fog uniforms to move the global fog mode setting to the viewpoint buffer."
This reverts commit 8b26b6dd1e.

This was causing problems with light mode 2 because some edge cases were no longer handled properly.

1eb1d8d280 - fixed math imprecisions in horizon vertex generation.
Floats are not precise enough to be used as a loop counter.

1c3d4b46c6 - fixed the use of Doom-Legacy-style 3D floor lighting in light mode 8.
Legacy used some strange blending formula to calculate its colormaps for colored 3D floor lighting, this is not available in the software lighting mode, so for these the engine has to temporarily revert to light mode 2 to render them correctly.

22e8c57a59 - reset the viewpoint buffer only once per scene, not per viewpoint.
This doesn't work for camera textures because they are a separate viewpoint.

5e39890118 - use a uniform buffer for per-scene data like rotation matrices. 2018-09-02 18:40:36 +02:00

7e69cd862e - restore the viewport after the SSAO pass.
This runs through the generic postprocessing code which restores the screen's viewport but since this is run in the middle of the scene it needs to restore the scene's viewport (i.e. the window controlled by screenblocks.)

2382b9a238 - fixed: GLScenePortal did not forward IsSky to its backing object. 2018-07-22 21:18:00 +02:00
Christoph Oelckers
f62e2f9ba3 - fixed: The stencil cap may never write to the depth buffer.
Due to the way nested portals work this will block rendering of the nested cap entriely and cause some visual glitches when looking straight up or down in such a sector.

446be98f37 - fixed light application logic for flats.
The light mode check wasn't done properly anymore after merging GLPASS_ALL and GLPASS_PLAIN.

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.

Christoph Oelckers
6ebec37baf - moved all portal code that sets up a scene to be rendered into API independent code and let it be handled by a common wrapper class. 2018-06-23 23:03:34 +02:00
Christoph Oelckers
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
Christoph Oelckers
282fdac660 - made the static portal state a struct inside the Renderer object 2018-06-23 13:25:59 +02:00

82d7e5970f - moved the clipline uniform to the viewpoint buffer.
This was the final one of the per-scene values that could be taken out of the render state.

7f0e29db48 - fixed clip plane setup.
This had to be reordered so that the clip plane gets set before applying the uniforms.

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.

b244fa2c8b Took the main render function out of GLSceneDrawer and moved them into FDrawInfo
First step of eliminating the intermediate SceneDrawer class which has become mostly redundant.
