8e2ebe15fe - removed several unused variables from OpenGLFrameBuffer. 
- removed the LastCamera logic in RenderView. This code predates the first GZDoom release and apparently was only added because back then R_SetupFrame was not fully compatible with the hardware renderer. Today it is not needed anymore.

9e70771da3 - Added a check to allow shader storage buffers on GL 4.3 Intel drivers. It doesn't work if GLSL version is set to 4.0 and the feature activated via extension. 2017-03-11 20:14:18 +01:00

fec958cc0a - finally managed to get rid of the DWORD type. 
This one was particularly nasty because Windows also defines a DWORD, but in Windows it is an unsigned long, not an unsigned int so changing types caused type conflicts and not all could be removed.
Those referring to the Windows type have to be kept, fortunately they are mostly in the Win32 directory, with a handful of exceptions elsewhere.

bd7476fb8d - untangled r_defs.h from actor.h 
Both files can now be included independently without causing problems.
This also required moving some inline functions into separate files and splitting off the GC definitions from dobject.h to ensure that r_defs does not need to pull in any part of the object hierarchy.

9b87a167d7 - replaced a large batch of DWORDs. 
Most of those which still rely on ZDoom's own definition should be gone, unfortunately the code in files that include Windows headers is a gigantic mess with DWORDs being longs there intead of ints, so this needs to be done with care. DWORD should only remain where the Windows type is actually wanted.

e080f0cf89 - removed Windows.h include from gl_system.h and cleaned up that file. This means that most OpenGL sources can now be compiled without any Windows dependencies, which is significantly faster. 2017-03-09 13:19:51 +01:00
Christoph Oelckers
05919a2926 - remove Windows includes from gl_load.h 
This is one of two places that unconditionally pulled in all Windows headers into the GL code.
We also do not need the cruft for defining the standard integer types. GZDoom is C++11 which means that stdint.h will be present. So the madness with the definitions should be avoided to ensure that the types are always the same.

03e1cbcfc0 - removed Windows types from several files which don't need them. 
- split out the software renderer's video classes into their own file because they got included by all OpenGL sources.

c630b07011 - replaced SDWORD with int32_t globally. 
This type wasn't used in the software rendering code so it could be removed already. The other homegrown types will have to be dealt with later.

750c194959 - changed order of SwapBuffers and glFinish call. The new order with glFinish coming last is recommended by OpenGL and it fixes a stalling problem with portals and camera textures visible at the same time. 
- check and use WGL_EXT_swap_control_tear extension. The above change makes the system always wait for a full vsync with a wglSwapInterval of 1, so it now uses the official extension that enables adaptive vsync. Hopefully this also works on the cards where the old setup did not.

The old license was compatible with GPLv2 whereas combining GPLv2 and LGPLv3 force a license upgrade to GPLv3. The license of code that originates from ZDoomGL has not been changed.

8daaf61160 - predefine the vertex data for the blend overlay which will never change throughout the lifetime of the GLRenderer object. 2016-08-08 14:24:48 +02:00
Christoph Oelckers
9c9edbffdb - on older ATI drivers where the clip planes are broken, only disable the clip planes themselves, but not OpenGL 3.x so that dynamic lights still work as intended. 
- only disable clip planes on Windows, but not on Linux or macOS.
- If a driver reports full OpenGL 4.5 support, assume that all features are working properly.

def3ad7533 - refactored all 2D drawing to use its own vertex buffer which does not need to be mapped permanently. 2016-08-08 12:13:09 +02:00
Christoph Oelckers
04c59b434b - renamed WipeVertexBuffer to FSimpleVertexBuffer because this will be useful elsewhere, too. 2016-08-07 00:40:31 +02:00
Christoph Oelckers
6a66d0255d - use a dedicated vertex buffer for rendering the wipes. 
- fixed: The postprocessing shaders clobbered the render state's vertex buffer info by bypassing and not notifying it of the change.

7576e85cef - force use of shaders on all hardware, unless -noshader is specified. 
Right it's only for easy testing, so only the code that does the feature checking has been disabled.
 2016-08-06 13:06:55 +02:00
Christoph Oelckers
2e555e6dab - use client arrays on compatibility profiles instead of calling glBegin/glEnd. 
This eliminates most behavioral differences for FFlatVertexBuffer between both operating modes, now the only difference is where the buffer is located.

52e19c59b3 Revert "- let gl_draw_sync default to false." 
This reverts commit 616f84209b.

Now I remember why this is not active: This is causing some problems with interpolated plane heights. Since there is no synchronization with the vertex buffer, the next frame will reset all plane coordinates before the GPU can use them. This will require some rethinking about when to update the buffer - it cannot be done in the render data setup loop.

616f84209b - let gl_draw_sync default to false. 
No need to waste valuable processing time if we can let the GPU run in parallel with the code that generates the next frame.

0a94371974 - reinstated old code for rendering fog boundaries and mirrot surfaces without shaders. 
- added code for filling the render list for textured dynamic lights. This is not yet active because no code is present to handle this data.
 2016-05-03 23:28:42 +02:00
Christoph Oelckers
0e14f00b51 - fixed caching of texture sampler state for old hardware. 
- fixed handling of CLAMP_XY_NOMIP sampler mode. This cannot be lumped together with CLAMP_XY because it has different mipmap requirements.

f2f3fa6d09 - parched the texture precaching so that it compiles and works again. The real work will come later. 2016-05-02 00:13:00 +02:00
Christoph Oelckers
50ba1ecde8 - add menu patching for GL 2.x mode. 
- use stdint types in model code, because we have to start somewhere with the transition.

ca95371a27 - fixed: gl_load.c did not handle the GL 2.x fallback for the lack of glGetStringi correctly, if that function was missing it just crashed. 2016-04-30 17:16:16 +02:00

c29e96d369 - print buffer info only if the buffer type is used. 
- removed some GL specs that are not informative in GZDoom's context.

50ab301bd8 - fixed: If we want to support pre-GL3 hardware, we may not require the presence of glGetStringi. 2016-04-30 16:23:32 +02:00
