fac7c7a31c - abstraction of render style in render state. 2018-10-20 23:14:57 +02:00
Christoph Oelckers
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
Christoph Oelckers
a4f7fd2e46 - started splitting the render state struct. 
Reusable parts should be in hwrenderer later.

9a03ba3cc5 - renamed FRenderState to FGLRenderState. 2018-10-20 13:05:36 +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.

9253118bdc - removed the quad drawer class 
This isn't needed anymore.

74ba142eae - allow vertex creation for sprites in the setup pass. 
Currently only used by legacy hardware.
 2018-10-20 11:53:20 +02:00

00c8c6e3b2 - generate vertices for skybox sectors in the processing pass. 
Aside from the sprites this was the only other remaining use of FQuadDrawer.
 2018-10-20 11:22:55 +02:00
Christoph Oelckers
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.

ad80efd6be Prepared light buffer for multithreaded use 
This necessitated removing the reallocator because that cannot be done in a multithreaded context in OpenGL. The buffer should be large enough anyway, it it all gets used, slowdowns would be unavoidable.

There was also some simplification of the buffer alignment math for uniform buffers

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.

c8852b8fea - enabled the linear shadowmap filter. 
Although this doesn't look as good as the PCF version it is a lot less calculation intensive and therefore more suitable for weaker hardware.
It also tends to bleed through walls a lot less.

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.

Christoph Oelckers
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.

dd971805af - fixed: The viewpoint buffer was mapped write only but read from. On old hardware it wasn't even mapped. 
Changed to cache the needed value in a CPU-side array so that the buffer access is not needed.

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.

ecf6e3f620 Sanitized the Being/End2D interface so that it can be used to keep the attribute buffer mapped while processing 2D commands. 
For this to work the 2D mode has to be properly set and unset at the right places so that no double mapping occurs and no render operation can happen while in 2D mode.

b6ff468aaf - creation of dither texture no longer affects active unit 
Red checkerboard was rendered upon startup instead of
* the first saved game's thumbnail
* the first game frame

ecdc485e05 - Allow specifying monitor bits-per-channel for dithering output. Not all displays are created equal, so this option is actually important for specifying the exact amount for your display. 2018-08-09 15:13:26 -04:00

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.)

9768698eda - do not use SSBOs for dynamic lights on Intel graphics hardware for performance reasons. 
This was already disabled for GL 4.4 and lower but also needs to be done for Intel's GL 4.5 drivers.
Unlike before this is now exclusive to the light buffer, the shadowmap feature is not affected anymore, although that should be impossible to use anyway on all affected hardware due to lack of computing power.

d84497c85a - don't let the video scale let the screen end up with a client size less than 320x200, which may cause undefined behavior and trigger asserts in debug builds. 2018-07-22 11:40:12 +02:00

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.

Christoph Oelckers
2c86c4e942 - fixed: When deleting a camera texture's depth buffer, the corresponding variable must also be cleared. 
Thanks to OpenGL's messed up state system this didn't cause some clear failure but just reused the last bound buffer instead which may not have had a matching size.

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.

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.

74d8c929cc Give the clipper a reference to the current viewpoint 
This is both for efficiency and encapsulation. At last on MSVC in 64 bit, accessing global variables is very inefficient and the clipper was doing it repeatedly in its worker functions.

It is also one less place where the global viewpoint gets checked.

46d73e7b4b Pass ticFrac to the model renderer as a parameter 
This also removes the rather pointless gl_RenderModel functions because with their two lines of content they can just be placed inline.

b65b83edb3 - removed the hard screen resolution switch that still was present on Windows and cleaned up the entire video backend code from the remaining support code for this. 
Like Linux and macOS this will only support borderless fullscreen in the active desktop resolution now, which is what modern systems need.
The list of discrete resolutions has been removed as it makes no sense anymore with a fixed video mode - all the other scaling options remain active, though.

322488d1d1 - fixed: Horizon portals must be drawn in the context of their containing drawinfo. 
This data, however, was not passed along to the portal processor and resulted in null pointers when trying to access it.

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.

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.
