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.

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.

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.

caf80e74c4 - fixed multiplication/division mixup in TextureAdjustWidth. 
- fixed: For top textures an incorrect ceiling height was passed to DoTexture.

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
Christopher Bruns
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.

25d7eaed0a - fixed parentheses in ADynamicLight::DistToSeg. 
- floatifed OpenGL sector grouping.
- optimized light node collection. It should not create light nodes for out of range segs.

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

Christoph Oelckers
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.

1f64d7ee22 Fixed wrong starting frame for wipe animation 
Menu graphics appeared in starting frame with hardware renderer only
Software renderer was not affected as it reads pixels from front buffer instead of back buffer like OpenGL counterpart did

ae1571158c - fixed: The portal link table was not created when there were no sector portals. 
- fixed: P_TryMove could loop endlessly over a list of static portals when there was an error during portal creation.

7134f53638 - fixed: partial transparency wasn't taken into account 
Smoothing of edges could mark textures as non-transparent when hqNx upscale filter is used

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

87d6e03cc2 - should have saved before committing... 2016-03-05 13:09:49 +01:00
Christoph Oelckers
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.

ef9f3da31d - do not use the precalculated coordinates for non-linked portals because they are not static. 2016-03-04 14:41:24 +01:00
Christoph Oelckers
dbd89c2702 - refactoring of portal grouping for the renderer, to allow more efficient clipping. 2016-03-04 14:10:13 +01:00

213d7a75c2 - fixed: r_showviewer must always be true when rendering a mirror portal. 2016-02-26 12:09:59 +01:00

387f3dd03a - fixed compile errors due to changes in ZDoom. 2016-02-25 13:06:13 +01:00
Christoph Oelckers
e3ddc74eb1 - check r_showviewer when deciding whether to render the player sprite. This is necessary when camera and player end up on different sides of a portal. 2016-02-24 01:14:24 +01:00
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.
If this is not done, fog on the horizon plane can break.
 2016-02-21 01:38:41 +01:00
Christoph Oelckers
9af5dd357f - removed the camera adjustment in FGLRenderer::SetViewArea because this had already been done by R_SetupFrame. 2016-02-20 02:20:55 +01:00

Christoph Oelckers
0931134a9c - fixed: part of the special handling of projectiles being spawned near the camera also affected other actors, this caused the fly cheat to break. 2016-02-12 11:20:33 +01:00

7105a87a1e - fixed retrieval of mapsection for polyportals. 
- render wall portals on one sided lines.
 2016-02-06 19:19:18 +01:00
Christoph Oelckers
3683a8ac58 - implemented line-to-line portal rendering. So far working for two-sided portal lines - one-sided yet to come. 2016-02-06 12:32:47 +01:00
Christoph Oelckers
297cf52ac9 - copied line portal code from portal branch and made some adjustments to make it compile. Portal rendering is not yet working. 2016-02-06 05:17:47 +01:00
Christoph Oelckers
25f1dc86d5 - removed duplicate function definition. 2016-02-06 00:50:43 +01:00
Christoph Oelckers
e6337537ed - this was missing the double slashes... 2016-02-05 14:04:28 +01:00
Christoph Oelckers
c4b1b96484 - handle one particular edge case when checking if a line is completely behind a mirror. 
This is not really sufficient to detect all cases where something gets incorrectly flagged as ok, but it's the easiest one to detect.
 2016-02-05 13:47:07 +01:00

dda73b531c Merge branch 'master' of https://github.com/rheit/zdoom 
# Conflicts:
#	src/CMakeLists.txt
#	src/p_setup.cpp
#	src/r_defs.h
#	src/version.h

This only updates to a compileable state. The new portals are not yet functional in the hardware renderer because they require some refactoring in the data management first.
 2016-02-05 12:31:41 +01:00
Christoph Oelckers
b2158c5b96 - removed unneeded parameter. 2016-02-05 01:48:53 +01:00
Christoph Oelckers
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.
 2016-02-04 15:34:12 +01:00
Christoph Oelckers
0c8a817df4 - fixed wall clipping with 3D lights. 2016-02-04 01:12:18 +01:00

Christoph Oelckers
df9c59bcff - moved gl_builddraw.cpp to a new 'unused' directory and also added gl_sections, which is needed by the Build algorithm to preprocess the level. 2016-02-02 12:07:07 +01:00
Christoph Oelckers
d797415745 - fixed: dynamic lights did not relink themselves when their position changed. 2016-02-02 11:58:00 +01:00
Christoph Oelckers
22e9fc9b76 - re-fixed FTexture::CheckTrans 
The original broken code had it always reset the translucency info to 'not present'.
The first fix completely removed that line, although it was merely misplaced, but still necessary to avoid constant re-checking of the same texture.
 2016-02-02 11:37:39 +01:00
Christoph Oelckers
9453a8a7e6 - reuse the same vertex buffer data for all slices of a decal. 2016-02-01 21:50:55 +01:00
Christoph Oelckers
f11f86f05d - added light plane clipping for decals as well. 2016-02-01 21:45:26 +01:00
Christoph Oelckers
faa08410de - handle nocoloredspritelighting with 3D light splitter 2016-02-01 19:10:15 +01:00
Christoph Oelckers
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.
 2016-02-01 18:14:00 +01:00
Christoph Oelckers
1ad310e69b - only draw visible 3D-lights. 2016-02-01 16:13:07 +01:00
Christoph Oelckers
67fc35e738 - some cleanup of wall processing code. 
* removed SplitWall function
 * split PutWall into PutWall and PutPortal because none of the portal cases needs the overhead for normal walls.
 2016-02-01 01:49:49 +01:00
Christoph Oelckers
9305cd86a0 - remove the GLWallLightEntry type. Everything it contains can be retrieved from the existing lightlist just as easily, and this approach avoids a lot of memory allocations. 
- removed the SplitWall profiling timer because all it measures now is an almost empty function.
 2016-02-01 01:03:34 +01:00
Christoph Oelckers
71da7406bd - since we no longer split walls at 3D floor boundaries, those planes no longer need to be added to the vertex height lists. 2016-02-01 00:42:37 +01:00
Christoph Oelckers
53a389aafc - fixed: for untextured walls, the texture must be disabled before rendering. 
- fixed: untextured walls should never be passed to SplitWall.
- fixed: untextured walls should not be affected by dynamic lights (it's either fog boundaries or outsides of 3D fog volumes.)
 2016-01-31 22:24:48 +01:00
Christoph Oelckers
9ce6a7932c - implemented rendering of 3D lights with clip planes. 2016-01-31 22:04:20 +01:00
Christoph Oelckers
5448b335c6 - rewrote render loop for walls. Not working yet. 2016-01-31 21:10:59 +01:00
Christoph Oelckers
f86535407d - forgot this. 2016-01-31 00:52:50 +01:00
Christoph Oelckers
1d9ab5c632 - clean out GLWall::SplitWall and instead of actually splitting the wall just attach a list of lights to it. 
Actual handling will be in the rendering function because this doesn't need multiple vertex transfers to the GPU. All slices can be drawn from the same buffer with different uniform info being set.

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.

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.

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.

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.

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.

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.

1050013017 major cleanup of the texture manager: 
- use sampler objects to avoid creating up to 4 different system textures for one game texture just because of different clamping settings.
- avoids flushing all textures for change of texture filter mode.
- separate sprite and regular dimensions on the material level to have better control over which one gets used. It's now an explicit parameter of ValidateTexture. The main reason for this change is better handling of wall sprites which may not be subjected to such handling.
- create mipmaps based on use case, not texture type.
- allows removal of FCloneTexture hack for proper sharing of the same sprite for decals and other purposes.
- better precaching of skyboxes.

e132fc5eed - replaced GLEW with GLLoadGen for GL access. This allows to have a header that only contains what's actually required, namely OpenGL 3.3 plus glBegin and glEnd which are the only compatibility functions needed for the fallback render path. 
GLEW has two major problems:

- it always includes everything, there is no way to restrict the header to a specific GL version
- it is mostly broken with a core profile and only works if all sanity checks get switched off.

86d37e06f9 - lowered requirements of GL 2.x to OpenGL 3.3. 
There was one issue preventing the previous 2.0 betas from running under GL 3.x: The lack of persistently mapped buffers.
For the dynamic light buffer today's changes take care of that problem.
For the vertex buffer there is no good workaround but we can use immediate mode render calls instead which have been reinstated.

To handle the current setup, the engine first tries to get a core profile context and checks for presence of GL 4.4 or the GL_ARB_buffer_storage extension.
If this fails the context is deleted again and a compatibility context retrieved which is then used for 'old style' rendering which does work on older GL versions.

This new version does not support GL 3.2 or lower, meaning that Intel GMA 3000 or lower is not supported. The reason for this is that the engine uses a few GL 3.3 features which are not present in the latest Intel driver.
In general the Intel GMA 3000 is far too weak, though, to run the demanding shader of GZDoom 2.x, so this is no real loss. Performance would be far from satisfying.

A command line option '-gl3' exists to force the fallback render path. On my Geforce 550Ti there's approx. 10% performance loss on this path.

a8e9c1832f - decided to restrict the 2.0 beta to OpenGL 4.x with GL_ARB_buffer_storage extension and removed all code for supporting older versions. 
Sadly, anything else makes no sense.
All the recently made changes live or die, depending on this extension's presence.
Without it, there are major performance issues with the buffer uploads. All of the traditional buffer upload methods are without exception horrendously slow, especially in the context of a Doom engine where frequent small updates are required.
It could be solved with a complete restructuring of the engine, of course, but that's hardly worth the effort, considering it's only for legacy hardware whose market share will inevitably shrink considerably over the next years.
And even then, under the best circumstances I'd still get the same performance as the old immediate mode renderer in GZDoom 1.x and still couldn't implement the additions I'd like to make.

So, since I need to keep GZDoom 1.x around anyway for older GL 2.x hardware, it may as well serve for 3.x hardware, too. It's certainly less work than constantly trying to find workarounds for the older hardware's limitations that cost more time than working on future-proofing the engine.

This new, trimmed down 4.x renderer runs on a core profile configuration and uses persistently mapped buffers for nearly everything that is getting transferred to the GPU. (The global uniforms are still being used as such but they'll be phased out after the first beta release.

f710518903 - use a uniform array to store vertex data to render dynamic stuff on GL 3.x hardware without the ARB_buffer_storage extension. 
Due to the way the engine works it needs to render a lot of small primitives with frequent state changes.
But due to the performance of buffer uploads it is impossible to upload each primitive's vertices to a buffer separately because buffer uploads nearly always stall the GPU.
On the other hand, in order to reduce the amount of buffer uploads all the necessary state changes would have to be saved in an array until they can finally be used. This method also imposed an unacceptable overhead.
Fortunately, uploading uniform arrays is very fast and doesn't cause GPU stalls, so now the engine puts the vertex data per primitive into a uniform array and uses a static vertex buffer to index the array in the vertex shader.
This method offers the same performance as immediate mode but only uses core profile features.

b9a6fe80a4 Do not use the shader to handle STYLEF_RedIsAlpha. 
Turns out that the name doesn't accurately describe what it does.
It is correct for images that come with their own palette or are true color.
But for images using the game palette it doesn't use the red channel to determine translucency but the palette index! Ugh...

This means it cannot be done with a simple operation in the shader because it won't get a proper source image. The only solution is to create a separate texture.

 2014-05-11 19:44:19 +02:00

7793bbbcc9 Further cleanup of lighting code. 
- remove thing color from lighting calculations.
- implement alpha textures and inverse sprites for infrared as texture modes. This still requires some handling for the alpha texture mode for non-shader rendering because there is no way in the fixed pipeline to do it. The inverted texture effect can be done with a texture combiner.
- fixed: ThingColor for sprites was set in the wrong place. It must be in the Process function, not in the lighting calculation.
- added functions for isolated calculation of sprites' dynlight color.

f3a9cb0cfa remove special texture creation for fullscreen colormaps. 
On GL 3.x+ this isn't needed at all and on older hardware it causes performance issues, in particular with hires textures due to impossibility of precaching.
In addition it forces some really awkward handling of lighting for things that have their own color, like stenciled sprites or particles.

With this special case gone it will be possible to handle this case in a saner manner than it is right now.

As compensation for older hardware a fullscreen blend will be drawn over the entire screen. This won't be 100% accurate but it's preferable to keeping the current method.

Christoph Oelckers
7d3beb665b - rewrote vertex buffer code to require GL_ARB_BUFFER_STORAGE extension. 
This means it won't work anymore on anything that doesn't support OpenGL 4.0, but I don't think this is a problem. On older NVidia cards performance gains could not be seen and on older AMDs using the vertex buffer was even worse as long as it got mixed with immediate mode rendering.

94b06900cb - got rid of a lot of stuff that's no longer required with GLEW.
