cc10fe9bc3 - fixed: The stereo3D code accessed the global 'viewsector' variable at a place where it no longer contained a correct value. 
- fixed: The same code did not exclude camera texture views from drawing the 2D overlay.

16cb4407a4 - disabled 'isVisibleToPlayerClass' check for dynamic lights affecting sprites. 
Calling this function in the inner loop of a time critical rendering function apparently wreaks havoc with the CPU instruction cache - even though the function doesn't do anything substantial.
This needs some more in-depth investigation why just having that call can increase sprite rendering time by a factor of 10 and more if there's many lights in view.

abf11f1a12 - print an error message if GL_ARB_sampler_objects cannot be found. 
GZDoom requires this extension and all supported hardware has drivers implementing it but there still seem to be people out there who stuck to some older, obsolete drivers that don't.

065b7f9ad2 - fixed: The CollectSectorStack functions had a local sector_t variable used by gl_FakeFlat which caused a stack overflow. Using the global one defined at the top of the file is ok here. 2015-05-29 12:03:50 +02:00

cf7cb4f00f - use hardware clip planes to split translucent walls and sprites by 3D floor planes. 
This method has the advantage that it also works for models, xy-billboarded sprites and walls that require complex splitting of the polygon. The old method using actual polygon splitting only works for strictly vertical data that could be trivially split in two.

45526c2769 - basics for using hardware clip planes to split translucent stuff by 3D floor planes. 2015-04-05 18:55:21 +02:00
Christoph Oelckers
bead3e046b - fixed weapon positioning again, after finding out that the first fix just worked around the actual problem: The entire coordinate calculation must be done in floating point with no integer math at all. Due to roundoff errors the stored int values needed for wall and flat placement significantly lack precision and with the high scaling factor that needs to be used for weapon HUD sprites these can easily become several pixels. After fixing this the border around sprite textures could be reverted to one pixel again. 
- fixed: The 'may not be expanded' state should be stored in the texture and reused later. This also needs to revalidate the material if it decides that expansion should be disallowed.

Christoph Oelckers
67334bfa2b - calculate weapon positions fully in floating point to avoid roundoff errors. 
- In order to get reliable results the empty border around scaled sprites must be the same scale as the sprite (i.e. 2 pixels for 2x scale and 4 pixels for 4x scale.)

7701d54b1f - fixed: associated dynamic lights took the sprite/frame info from the actor's current state instead of from the actor's current sprite and frame, which may differ in case some placeholder sprite is used in the state. 2015-03-15 12:24:28 +01:00

a5a53c51e6 - fixed: The flat drawing code assumed that the first element of the light list originated from the sector itself. This had been true formerly but in some situations it no longer is. 2015-02-10 21:52:19 +01:00
Christoph Oelckers
00639121c0 - added the missed parts of camera roll in gl_scene.cpp. 2015-02-10 20:34:10 +01:00
Christoph Oelckers
8a9692c29f - fixed: The code which decided whether to clamp two sided middle textures used the texture size instead of the render size for the specific linedef, meaning that any per-sidedef scaling was ignored. 2015-02-10 20:16:25 +01:00
Christoph Oelckers
a578ff5d06 - fixed a problem with some older AMD drivers: Normally calling glBindBufferBase should imply a call to glBindBuffer, but on these drivers it was never done, which resulted in the light uniform buffer never being created... 2015-01-24 13:13:54 +01:00

4f08b20df5 - consider pixel stretching when rendering models. For non-voxels an aspect ratio of 1:1 must always be assumed while voxels need to be stretched so that 1 voxel unit == 1 map unit. 2014-12-31 12:53:29 +01:00
Christoph Oelckers
e6d59ec429 - fixed: with aspect ratio compensation in the view matrix it is necessary to adjust the view pitch for this because the playsim does not know anything about pixel ratio. 2014-12-31 12:04:55 +01:00

315827015c - made aspect ratio correction factor configurable through MAPINFO. 2014-12-29 23:52:20 +01:00
Christoph Oelckers
45cf65afbd - moved the aspect ratio correction factor from the projection to the view matrix where it should have been from the start. 
- removed the mCameraPos variable in FGLRenderer because it was only used in one place where it is just as easy to use the global viewx/y/z variables directly.

fbfe0f1e7a - fixed: y-clamped textures with negative scale need to shift their texture coordinates into the proper [0..1] range. 2014-12-26 11:53:38 +01:00

c66a211200 - fixed: The sky renderer must not only alter the light mode but also reset the software light level to a 'disabled' value. 2014-12-25 22:45:40 +01:00
Christoph Oelckers
ffa069205f - fixed: For fullbright sprites, a weapon's extra light must be ignored because it can be negative. 2014-12-25 18:30:34 +01:00

0bc2c0094a - fixed: For cubemapped skies with one texture for all 4 sides the texture was never set before rendering. 2014-12-19 16:35:34 +01:00
Christoph Oelckers
717c82ee4a - On Intel, we have to disable shader storage buffers because their complier contains a bug disallowing unsized arrays. 2014-12-01 09:58:23 +01:00
Christoph Oelckers
ec627d94dd - fixed: The depth clamp setting needs to be tracked per portal so that it can be properly restored afterward. 
Regular skies need it off but SkyViewpoints need it on - and all others need to use the parent's setting.
So without engine side tracking we can end up rendering the sky with this setting off, resulting in omission of the fog layer.

eb753a0b7c - fixed: We also should use the proper 'copied' info for the non-inverted planes. 2014-11-27 10:49:03 +01:00
Christoph Oelckers
99d81621f9 - fixed: The 'copied' information of a 3D floor plane should only apply to that particular plane, but never the opposite one of the same 3D floor. 2014-11-27 10:46:28 +01:00

a7f4185981 - now that we don't have to care anymore about SVN-related merging problems, let's save the 3 global variables of the GL renderer unconditionally, even if the software renderer is running. 2014-11-16 09:08:47 +01:00
Christoph Oelckers
b0a6c94fa4 - fixed: the translucency flag for the flags renderer was inconsistent between the light pass and the render pass on GL 3.x hardware, resulting in bad buffer indices being sent to the shader. 2014-11-09 12:10:33 +01:00
Christoph Oelckers
3e50db9bf0 - fixed: When setting the object color for a shaded decal, the alpha channel must be forced to be 255. The decal's AlphaColor contains the palette index in those bits. 2014-10-26 15:11:04 +01:00

3c7664a460 - we don't really need a bBrightmap in a texture. All it did was duplicate some functionality of bMasked.

e5cd90f323 - use separate vertex buffers per model to avoid large memory usage peaks. Also delete the geometry data for the models once it has been copied into the vertex buffer. 2014-10-24 11:43:25 +02:00
Christoph Oelckers

5302a10a7d - diable software lighting for textured automap. 
* since it is designed for software-style light diminishing it doesn't work for 2D.
* additionally it left the lighting state in an unsuitable setting for further 2D rendering.

Christoph Oelckers
5d032f3fcf - fixed: Since the engine can no longer change renderers on the fly, thanks to ZDoom's messed up video startup code, we have to abort with a fatal error if we can't create a GL context. Otherwise the user will never see a meaningful message. 2014-10-06 10:00:02 +02:00

Christoph Oelckers
fd3128a164 - fixed: When changing enhanced nightvision mode the shaders need to have their fixed colormap state reset to ensure that the new settings get used. 
- fixed: The shader code for handling special fixed colormaps did not use the color vertex attribute which was most evident with the 'shadow' render style on the spectre.
 2014-10-05 09:40:36 +02:00
Christoph Oelckers
48da2f87bb - fixed: The light buffer index must not be reset between rendering a camera texture and the main scene. 
Since rendering is asynchronous, the camera texture scene may not be finished once the main scene's lights get filled in. Unfortunately forcing a synchronization with glFinisg has bad side effects on performance the only remaining option is to use separate parts of the buffer for both scenes, which in extreme cases may increase the light buffer's size - but on modern hardware that shouldn't be a problem.

c773a500f2 - only activate shader storage buffers on modern drivers also supporting GL_ARB_buffer storage. Early adopters of this extension (i.e. older AMD drivers mainly) tend to implement this badly. 2014-09-17 09:01:16 +02:00

Christoph Oelckers
8e7e16f73a - fixed: The light uniform buffer may not be mapped with GL_MAP_INVALIDATE_BUFFER_BIT, because it needs to be mapped for each portal in a scene but it must preserve the existing data for the remaining translucent objects. 2014-09-15 10:27:09 +02:00
