b90173ed21 - fixed: ADynamicLight::visibletoplayer was not initialized for placed lights when restoring a savegame. 2016-05-08 09:34:22 +02:00
Christoph Oelckers
ab8a647433 - fixed the disabled visibility rules check for dynamic lights by doing the actual check in the light's Tick() method and letting the renderer only use the result. 2016-05-04 11:33:18 +02:00

faeb0303fe - renamed ADynamicLight's intensity properties to radius, to have their name match their meaning. 2016-04-17 13:53:29 +02:00

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.

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.

a27181cb0b - partial adjustments.
No point changing all the viewx/y/z stuff when that is about to get floatified next.

95d36670cf - that portal check was not correct. 2016-03-10 15:15:37 +01:00
Christoph Oelckers
365c192a1d - added portal support for dynamic lights.
This requires fixed offsets so it only works with linked portals.

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.

d797415745 - fixed: dynamic lights did not relink themselves when their position changed. 2016-02-02 11:58:00 +01:00
Christoph Oelckers
342f1abcc7 - fixed: flickering dynamic lights with their first intensity value larger than the second one weren't properly linked into all touching sectors. 2016-01-30 00:45:47 +01:00
Christoph Oelckers
5816049510 - made necessary adjustments for the coordinate refactoring in ZDoom. 2016-01-21 12:36:37 +01:00
Christoph Oelckers
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

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
Christoph Oelckers
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
Christoph Oelckers
bca47bb9bc - removed debug code.
- fixed: planes that are created by splitting translucent 3D-floors may never be rendered.

36b35e85f3 - fixed: overflow checks for dynamic light buffer were not correct. 2014-10-23 12:06:00 +02:00

b2cf7d6512 - fixed memory leak: The sector links for dynamic lights were never freed. 2014-09-21 12:40:08 +02:00

43e2d704a3 - always use glPolygonOffset to render translucent geometry. 2014-09-20 09:04:36 +02:00
Christoph Oelckers
92dcf2e5ef - fixed some of those supremely annoying and supremely pointless GCC/Clang compiler warnings. 2014-09-17 11:03:05 +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

1a70a6aabc The light buffer should check for shader_storage_buffer_object rather than buffer_storage. 2014-09-14 14:29:13 -05:00

a2dc4afe3f - screwed by the editor's autocompletion... (wrong GL flag was used...) 2014-08-19 14:25:47 +02:00

00d7707aef - allow reallocation of light buffer if more lights are needed.
- added a light preprocessing pass to the renderer so that a non-persistent buffer can be used with minimal mapping/unmapping. This only gets used if necessary because it adds some overhead to the renderer.

a97b58fa27 - added check for light uniform buffer overflows, because uniform buffers on Intel are rather small. 2014-08-02 20:41:13 +02:00

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.

7967082e60 - use the light buffer to handle dynamic lighting. 2014-08-01 20:59:39 +02:00

1ec58011d2 - start of light buffer implementation so that we don't have to use uniform arrays which appear to be broken on AMD. 2014-07-31 00:44:22 +02:00
Christoph Oelckers
b8bcbe819b - removed texture based dynamic lighting. For GL 3.x the shader approach is always better.
- fixed: sky fog was not unset.

54297acde4 - removed obsolete gl_lightbuffer code.
This never worked properly and by now far better options are available to solve the problem of dynamic light data uploads.

Christoph Oelckers
2925c96b59 removed all GL 2.x code.
After thinking about it for a day or so I believe it's the best option to remove all compatibility code because it's a major obstacle for a transition to a core profile.

978ace241c - removed all code that mixes together the different lighting methods. Now everything goes through the 3 different light parameters in the render state.
- removed cm parameter from many functions.

52056a05bd - changed handling of DynLight in shader to serve as a global dynamic light color for all lighting modes. 2014-05-11 16:49:17 +02:00
