c946edd9bf - instead of copying the sector planes to GLWall, just store pointers to the front and back sector for later use. 
Until now this wasn't doable because these could have come from hw_FakeFlat which only were local copies on the stack.
With the recent change these faked sectors live long enough so that they can be passed around here.

a90655b295 - cache the results of hw_FakeFlat for the remainder of the current scene instead of storing this in local variables. 
An exception is made for the sprite drawer which needs to call this in the worker thread on some occasions for as-yet unprocessed sectors.
This case may not alter the cache to avoid having to add thread synchronization to it.

The main reason for this change is that pointers to such manipulated sectors can now be considered static in the renderer.
Due to them being short lived local buffers it was not possible to carry them along with the render data for information retrieval.

f6af50fc74 - restored portal code that shouldn't have been deleted. 2018-11-08 20:39:44 +01:00

f2e593f8bf - disabled the hack for fixing the original design of the portal in KDiZD's Z1M1. 
This portal got fixed in a later re-release of KDiZD and no other portal needs this runtime fix to my knowledge.
The main problem here is that this runtime fix requires some manipulation of the render data that does not work anymore.

Should other maps need this fix as well they are probably best served with a compatibility entry.

ddc75f7ba5 - made the common render hacks functional again as separate render items. 2018-11-06 20:31:44 +01:00
Christoph Oelckers
a6e77ae094 Refactored the render hack storage so that it can be decoupled from the regular GLFlat render items. 
Having these in there makes it impossible to change render techniques so these are better done as separate items.

ba66c0c889 - changed dynamic light traversal to use sections instead of the subsectors. 
This is mostly complete, except for handling intra-section sidedefs.

9ddca3c3a9 - removed the subsector light lists as a preparation step to move over the light traversal code to use sections instead of subsectors. 2018-11-05 22:35:24 +01:00
Christoph Oelckers
375dd7e28f - the sections are now being used as the smallest element to draw flat planes. 
This also removes one piece of code that was used to cope with the missing clip planes on old ATI cards, so support for those will most likely have to be dropped in the near future.

d7db00d92e - sector rendering refactoring for sections - work in progress. 2018-11-05 01:01:48 +01:00

2dec7bb1e5 - added a non-multithreaded option for the renderer and fixed a few places where the wrong sector was used 
The render_sector is only relevant for flats, but never for walls or sprites!

91df3f8c73 - added option to disable alpha testing for user shaders. 2018-10-31 15:56:20 +01:00

37166b5faf - fixed missing binding of the light buffer. 
I thought this wasn't needed but apparently the buffer refactoring caused this not to be done automatically anymore.
Best have it once at the start of each frame where the cost is negligible.

41fd34e424 - use standard sprite lighting for voxels. 
Per-pixel lighting requires normals which voxels do not have.

3a6f186aa0 - removed memcpy workarounds from GLWall, GLFlat and GLSprite after making sure that all 3 are trivially copyable. 2018-10-31 11:51:52 +01:00

790b121195 - added a bit of profiling code to the multithreaded parts of the renderer. 2018-10-31 10:20:06 +01:00

01a0af8ad1 - simplified the render job interface. 
Since the job nodes were already taken from a static array, the added linked list isn't really needed. All we need is a read and a write pointer into the array, This can even be done without a spinlock as long as we assume that the list never overflows.

e4d2ec8cb2 - added a few comments to the renderstate to document where certain functions are used. 2018-10-31 08:16:44 +01:00

aafa445aac - fixed stencil marking for SSAO. 2018-10-30 23:33:45 +01:00

e2e34f5245 - cleanup of the buffer binding interface. 
Some stuff is not really needed and the vertex buffers no longer need to insert themselves into the render state.

1be1470d47 - cleanup of hw_bsp.cpp. 2018-10-30 22:19:55 +01:00

48bc5550d7 - removed the Bind function from FFlatVertexBuffer. 
This is not flexible enough. There was already one place where this was not supposed to go through the render state.
The new interface allows more general use of the contained buffer objects.

55df324d16 - basic multithreading for the render data generation. 2018-10-30 14:58:43 +01:00

b56e80a556 - disabled the buffer reallocation option for the light buffer. 
The entire idea with CPU side buffering simply can not work since the buffer is being used live. To compensate the buffer's size was doubled.

2aac222d35 - fixed compilation on macOS 
error: non-constant-expression cannot be narrowed from type 'unsigned long' to 'int' in initializer list
error: unknown type name 'OpenGLFrameBuffer'

47ae42d636 - fixed: for sectors that have to be drawn per subsector the render state was not applied. resulting in random garbage. 2018-10-29 17:52:44 +01:00

893e08df70 - moved DrawScene to GLRenderer and call it through std::function. 
This was the last remaining virtual override of HWDrawInfo.
With it removed this type is now fully API independent.

8a0596893b - fixed dynamic light profiling counters. 
The draw counters were never incremented and this should be reset only once per scene, not once per viewpoint.

9f9d747a6b - moved all methods that would involve command buffer manipulation in Vulkan to FRenderState, because that's the object that would serve as command buffer builder. 2018-10-28 22:20:51 +01:00
Christoph Oelckers
2ee2766812 - moved more code from FDrawInfo to HWDrawInfo. 
The entire setup/takedown code did not reference any API specific data. The only thing needed is a global virtual creation function.

1ca811d4a8 - moved more code out of FDrawInfo. 2018-10-28 19:19:46 +01:00

cb4ffbf053 - moved the draw lists back to the API independent side. 
The original idea was to let Vulkan do this completely differently, but if that comes to pass it should be done without having generic data maintenance code on the API side.
