d84e079282 - render partial sprites oon the back side of a portal for actors in front of it. This is needed because the stencil will clip away those parts. 2016-04-30 16:57:53 +02:00
Christoph Oelckers
c29e96d369 - print buffer info only if the buffer type is used. 
- removed some GL specs that are not informative in GZDoom's context.

70bf649364 - added clip planes for line portals and mirrors. This should eliminate the remaining problems with some visible geometry in front of the portal, it is also necessary to handle sprite splitting across line portals properly. 2016-04-29 12:26:57 +02:00
Christoph Oelckers
21283b18f4 - preparations for using clip planes on line portals. 2016-04-29 01:48:06 +02:00
Christoph Oelckers
e3fad118d2 - use the templated warp functions instead of the limited GZDoom 1.x version. gl_WarpBuffer has been removed. 2016-04-28 19:04:01 +02:00
Christoph Oelckers
434e39e62f - made adjustments to ZDoom's last changes. 2016-04-28 17:55:58 +02:00

d4806f82ca - reinstated some texturing-based dynamic light code. Not active yet and not tested yet. 2016-04-28 00:58:44 +02:00
Christoph Oelckers
ee7a4daa8c - preparations for textured dynamic lights. 2016-04-27 23:19:54 +02:00

3be33b5725 The GL part of Quake Rolls. 2016-04-27 13:49:51 +02:00
Christoph Oelckers
73823e6a09 - fixed the texture size checks for determining if a camera texture requires offscreen rendering were wrong and checked the scaled size, not the physical size. 2016-04-27 02:56:55 +02:00
Christoph Oelckers
09f54b0940 - cleaned up the clip plane management for portals. 
Unfortunately the math behind the old clip planes is utterly impenetrable and so poorly documented that I have no idea how to set that up, so it is deactivated for now. It wasn't working anyway.
 2016-04-27 00:41:00 +02:00
Christoph Oelckers
066d5c63e2 - better be safe and not call GL_CLIP_DISTANCE functions on old hardware. 2016-04-26 21:55:17 +02:00
Christoph Oelckers
3faf5afa3a - re-added software translucency splitting for old hardware. 2016-04-26 21:49:30 +02:00
Christoph Oelckers
b06c86db38 - added old wall splitting code as a fallback for old hardware. 2016-04-26 21:42:15 +02:00
Christoph Oelckers
6e1b21d513 - added back sprite splitting for low end, plus some dynamic light code. 2016-04-26 21:31:24 +02:00
Christoph Oelckers
89f36fb963 - enabled texture and model matrices for shader-less rendering and fixed the sky cap color application. 2016-04-26 20:45:56 +02:00
Christoph Oelckers
9d71c91f01 - reenabled software warping for shader-less rendering. 2016-04-26 20:20:00 +02:00
Christoph Oelckers
924b72b633 - added workarounds for the invulnerability colormap for non-shader rendering. Unlike the shader based versions these do not decolorize the screen. The advantage to the old texture duplication is that this is far less stressful on performance. 2016-04-26 20:02:57 +02:00
Christoph Oelckers
913e3df7e3 - fixed display of alpha textures without shaders. 
As it turned out, the translation's alpha channel was clobbered by the whole setup.
 2016-04-26 19:11:32 +02:00
Christoph Oelckers
7e6e2bc0a8 - stated adding GL 2.0 compatibility handling 2016-04-26 18:24:02 +02:00
Christoph Oelckers
eb27057853 - enable shader-less rendering. Still very incomplete, but at least the basics are working. 2016-04-26 16:44:03 +02:00
Christoph Oelckers
3b1500438d - got rid of VAO's. they have no impact on performance and are a general nuisance if some render paths cannot use them. 
- cleaned up gl_interface and removed gl.compatibility.
 2016-04-26 16:26:34 +02:00
Christoph Oelckers
f066457a48 - add shader patching to allow running the engine with GLSL 1.2. 
- made some initial preparations for the shader-less fallback path.
 2016-04-26 15:26:52 +02:00
Christoph Oelckers
ee9a40f5e9 - replace FLOATTYPE with float in stereo3d code. 2016-04-26 15:20:27 +02:00
Christoph Oelckers
090d13b915 - updated gl_interface to deal with older GL versions. 
- added the framework for allowing multipass textured dynamic lights again.
 2016-04-26 15:20:26 +02:00
Christoph Oelckers
97bed58d7d - use a compatibility mode version of gl_load, so that the fallback GL 2 code can get its definitions. 2016-04-26 11:32:40 +02:00
Christoph Oelckers
22b7a38539 - fixed incorrect sky texture check with Transfer_Heights. The actual sector was checked, not the one created by gl_FakeFlat. 2016-04-24 14:17:06 +02:00
Christoph Oelckers
f77c4642cb - made the adjustments. 2016-04-24 13:35:43 +02:00
Christoph Oelckers
0d17459c36 - do not disable sampler objects with -gl3. 2016-04-23 15:47:51 +02:00
Christoph Oelckers
9d9219795a - adjusted function names. 2016-04-23 13:48:25 +02:00
Christoph Oelckers
38f1213387 - made some adjustments. 2016-04-23 13:35:51 +02:00
Christoph Oelckers
a17e0b70d2 - adjustment for function name changes. 2016-04-23 11:38:33 +02:00
Christoph Oelckers
6450752399 - made it compile again. 
The software renderer float conversion removed viewx and viewy which are still needed for efficient position checks against nodes without constant float->fixed conversions.
 2016-04-23 10:50:19 +02:00
Christoph Oelckers
c786b65727 - allow the engine to run without sampler objects. This will create some overhead in the texture code, but that's still better than having to error out on those few systems where it may be an issue. 2016-04-22 19:54:51 +02:00
Christoph Oelckers
f299248c8a - be a bit more careful with using unvalidated portals for checking render hacks. 2016-04-22 09:15:22 +02:00
Christoph Oelckers
1c7b512cc0 - GL handling of new portal data organization. 
This also fixes some oversights with plane and horizon portals which were included in several checks.
 2016-04-20 20:08:53 +02:00
Christoph Oelckers
aa12772e07 - crash fix and minor optimization. 2016-04-20 13:18:53 +02:00
Christoph Oelckers
1f32f5a258 - some minor fixing and cleanup on gL portal code. 2016-04-20 11:39:41 +02:00
Christoph Oelckers
573d80f144 - render sproites through sector portals. 2016-04-18 23:52:15 +02:00
Christoph Oelckers
741f054601 - clip sprites to linked sector portal planes. 
This is the first part of properly handling those transitions.
 2016-04-18 16:27:04 +02:00
Christoph Oelckers
0d7bd368fa - added some fudging to draw the outer linedefs of a portal area. 
This is needed so that polyportals get rendered correctly. For non-polyportals these will normally be outside the portal window and just be discarded.
 2016-04-17 15:46:04 +02:00
Christoph Oelckers
faeb0303fe - renamed ADynamicLight's intensity properties to radius, to have their name match their meaning. 2016-04-17 13:53:29 +02:00
Christoph Oelckers
8a010ab871 - allow 90° rotations in skybox sectors. 2016-04-17 11:58:26 +02:00
Christoph Oelckers
0a35027f67 - fixed use of validcount for the GL renderer. 
This needs to be incremented more locally to the place where it is used, so that it is guaranteed that each viewpoint that needs to be rendered increases it.
As a result the uses in the portal code could be removed.
 2016-04-17 10:39:29 +02:00
Christoph Oelckers
95de1faa80 - fixed: The portal coverage builder initialized node_t::len differently than the polyobject splitter. 
This was creating quite a mess when loading savegames with both portals and polyobjects.
 2016-04-17 01:16:46 +02:00
Christoph Oelckers
a0a530945d - added new sector type 90 which designates a sector that is being used as a cubemapped skybox, in case someone wants to make one of those without using an actual sky for this. 2016-04-14 13:22:15 +02:00
Christoph Oelckers
328047ea28 - fixed issues with recent Stereo3D submission: 
* there was a CVAR that was only defined in Windows
 * code did not compile with GCC.
 * due to bad setup it disabled multisampling.
 2016-04-14 10:16:04 +02:00
Christoph Oelckers
caf80e74c4 - fixed multiplication/division mixup in TextureAdjustWidth. 
- fixed: For top textures an incorrect ceiling height was passed to DoTexture.
 2016-04-13 23:09:45 +02:00
Christoph Oelckers
bffb7444a0 - removed portal check for distance check in GL code. 2016-04-13 19:33:45 +02:00
Christoph Oelckers
d66a28fcde - fixed offsetting of player weapon sprites. 2016-04-13 16:24:25 +02:00
Christoph Oelckers
d0b30f31e1 - fixed: Checking for slopes at untextured bottom parts of the wall checked the ceiling's slope not the floor's. 2016-04-13 11:41:51 +02:00
Christoph Oelckers
37f43617d9 - make distance check 3D and use proper viewpoint. 2016-04-13 11:35:05 +02:00
Christoph Oelckers
bec3208efd - added support for distancecheck property. 2016-04-12 19:50:29 +02:00
Christoph Oelckers
a411b93e1d - fixed: The dynamic pulse light should always use its maximum size for linking into the sector lists, just like the other types with changing size do. 
These limking operations are not cheap so it's preferable to have them affect a bit more geometry than running the linking code each tic.

bde94879ad Restore stereoscopic geometry correctness, by inserting a minus sign where it always should have been, after finding that a compensating minus sign, where it probably should not have been anyway, was removed during the recent floating point refactoring. 2016-04-09 21:46:14 -04:00
Christoph Oelckers
84c8f38038 - fixed: The divisions in FTexCoordInfo::TextureOffset and RowOffset were turned into multiplications when converting to floating point. 2016-04-10 00:45:48 +02:00
Christopher Bruns
072a5e60ae Naive change to get latest version to compile. 2016-04-09 17:03:55 -04:00

c6fa01dfbf Reimplement blue/yellow and quadbuffered stereo, this time with an additional CVAR gate on quadbuffered, for better hardware compatibility.obj 
Something is terribly wrong with the separation in all stereo modes now though.

cbcde3a950 Fixed check for alpha channel in texture to select hqNx upscaling mode 
Now it's the initial check with the adjustment in mode indices only, as old hqNx MMX indices (4..6) are now occupied by generic hqNx implementation

5a2eac8f15 - floatified vertices and removed the now redundant fx and fy members. This needs an added check for polyobject origins, though, so that such subsectors don't get rendered. 2016-04-03 11:40:14 +02:00
Christoph Oelckers
8a20f901a3 - removed the non.slope special handling in the wall processing code. 
This may have made some sense when I added this 11 years ago but on a current computer it actually hurts performance a bit due to the branching that is involved - the code runs a bit faster with those special cases removed.

365c192a1d - added portal support for dynamic lights. 
This requires fixed offsets so it only works with linked portals.

26a05857d0 - fixed: Camera textures should not intercept and clear the NoInterpolateView flag. 
Thanks to some really bad use of a global variable this was causing problems with the inverted order in which GZDoom needs to draw this stuff.

Christoph Oelckers
a901875925 - fixed: The horizon portal drawer must set the camera position for the shader. 
This gets lost when several portals are drawn sequentially and this is the only portal type which needs this information but doesn't go through the normal setup.

c129cb3ca4 - reinstated software clipping by light volumes for walls. 
It turned out that using hardware clipping planes exclusively to handle this cost more than it gained.
Now only the expensive or formerly impossible cases of intersecting light volumes or light volumes intersecting with the top and bottom of the wall polygon will use hardware clipping. The trivial cases will go back to software splitting.

2c55dcca27 - use hardware clipping to apply 3D lights to sprites. This solves all the problems with properly lighting models and billboarded sprites. 
- add some restrictions for the checks that exclude sprites which are too close to the camera. Most importantly, for clipping the first frame of a projectile, do not solely clip against the projectile's speed but use the player's radius as a limiting factor to avoid too large distances.

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.

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.

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
Christoph Oelckers
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.

045725de15 - use strncpy instead of sprintf tp init static char array to ensure that all elements get initialized. 2014-12-29 16:35:30 +01:00

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
Christoph Oelckers
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
Christoph Oelckers
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

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.

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

a25ed3c807 - fixed: inverted rendering for fuzzy things with light powerup was switched off due to change of render style. 2014-09-15 12:15:19 +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

acf6c259d8 - changed the handling of alpha textures. The only special case they need is with palette-less textures and this can be handled far more easily and robustly with a predefined translation instead of passing another parameter through all the layers of the texture management code. This also fixes problems with paletted PNGs that get used as an alpha texture because the old method clobbered the image's palette. 2014-09-09 13:21:36 +02:00

4bb320a27c - route texture binding through the renderstate class for better control. Currently it's just a direct passthrough but this will change. 2014-09-09 12:00:42 +02:00

49ec7beb8f - separate draw lists for walls and flats. This makes the sorting much more efficient because draw types no longer need to be checked in the compare function. This is a lot more important than having perfect texture order. 2014-08-30 13:04:41 +02:00
