35666f1e09 Fixed a nullptr crash with flatsprite actors. 2016-07-21 13:12:59 -05:00
Christoph Oelckers
c5db5dff99 - fixed a crash when initializing the GL portal data for an incomplete or inactive portal. Also did a bit of cleanup on this code, the 'delta' member was never used. 2016-07-16 12:45:49 +02:00

b3b2eb42c6 Added SurfaceSkin MODELDEF property, allows overriding MD3 per-surface skins. 2016-07-16 09:30:25 +02:00
Christoph Oelckers
f4b80a451e - fixed: The render style specific blend settings were overridden when adding code to ensure proper setup of all properties.
It turned out that the only thing that wasn't set is the alpha function, not the blend settings themselves.

e56196eb1a Disable facing camera rotations if the actor is a flat/wall sprite.
- It not only looks bad, it also throws off users when trying to make perfectly aligned images since the plane is distorted wildly.

cc8d84cd5d Fixed sprites defaulting to rotate around the center instead of the offsets. Seeing how it's still useful however, ROLLCENTER can still be used to center upon actors that are offsetted like monsters. 2016-07-13 09:31:22 +02:00

7b99c883e1 - use the exact same semantics and methods to handle player visibility as in the software renderer.
This fixes invisible player sprites in recursive line portals.
2016-06-18 12:14:20 +02:00
Christoph Oelckers
87d27b8db3 - fixed some crash issues with recent changes. 2016-06-18 10:01:24 +02:00

92e2ce2aef - adjustments for weapon rendering in GL.
This adds support for the new weapon state code and fixed some lighting calculations.
Note that this currently will not allow combination of HUD models with other sprite frames yet.

56ce6abbc2 Fixed splitting of walls in compatibility renderer
Any wall adjacent to 3D floor sector were not rendered at all
2016-06-05 12:38:23 +03:00
Christoph Oelckers
5017a192eb - fixed: The texture matrix was not reset after drawing the texture pass for multipass textured dynamic lights. 2016-05-19 12:22:39 +02:00
Christoph Oelckers
13da14e915 - disable dynamic lights on additively blended surfaces because it doesn't look good at all. 2016-05-18 22:20:18 +02:00
Christoph Oelckers
15c711f2a1 - added a missing break in the wall draw dispatcher. 2016-05-09 00:58:55 +02:00
Christoph Oelckers
d5eb1008a4 - implemented texture overlay pass for textured dynamic lights. 2016-05-08 22:07:18 +02:00
Christoph Oelckers
6753cddce1 - fixed: The HUD weapon drawer partially took the render state from the previous things that got rendered. Especially the blend mode could be randomly set to different values. 2016-05-08 09:22:38 +02:00
Christoph Oelckers
d61ec05c0f - draw texture based dynamic lights on walls. 2016-05-05 12:18:09 +02:00
Christoph Oelckers
2b92048a5b - renamed the texture coord variables in GLWall.
It makes no sense having them organized differently in this struct than what the rendering code needs. This saves one redundant copy operation and a function-local static variable.
2016-05-05 11:48:39 +02:00
Christoph Oelckers
51baa7d137 - added code to calculate light texture coordinates on walls. 2016-05-05 11:32:21 +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
Christoph Oelckers
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
0f8f08edfd - fixed: camera facing sprites need to orient themselves toward the actual camera position, not the view actor (which may be invalid or in a completely different part of the map if a portal is being rendered.) 2016-05-03 19:24:28 +02:00
Christoph Oelckers
b6af4677f3 - implemented model precaching. 2016-05-03 18:14:16 +02:00
Christoph Oelckers
6f2b0a6293 - rewrote texture caching so that not the base texture but the actually used translations for sprites get precached. 2016-05-03 01:00:52 +02:00
Christoph Oelckers
ec037bfd1a - fixed: The check for one-way portals in the renderer was incomplete. 2016-05-02 19:47:27 +02:00
MajorCooke
16bea6cf1f - Fixed: Roll must orient the rotation based on pitch, not the other way around. 2016-05-02 10:46:44 -05:00

51991ef22d * - render partial sprites on the front side of a portal for actors behind it. 2016-04-30 23:18:37 +02:00
Christoph Oelckers
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
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

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
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
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
090d13b915 - updated gl_interface to deal with older GL versions.

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

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
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
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
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
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

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
4af859094c - fixed: sprite clipping did not work anymore because the 'invalid' value was inconsistent.
- cleaned up the 'if' condition in PerformSpriteClipAdjustment,
- enabled weapon bobbing interpolation.

Christoph Oelckers
58eb64a7e0 - fixed a few fixed/float parameter mixups. 2016-04-03 12:54:47 +02:00
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.
2016-04-03 02:07:37 +02:00

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.
2016-03-12 17:43:36 +01:00
Christoph Oelckers
365c192a1d - added portal support for dynamic lights.
This requires fixed offsets so it only works with linked portals.
2016-03-08 21:22:12 +01:00
Christoph Oelckers
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.
2016-03-05 12:46:47 +01:00
Christoph Oelckers
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

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.

141065c3d5 - fixed: positioning of camera textures on 2-sided walls was not correct. 2016-02-14 14:33:52 +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
Christoph Oelckers
6a408b1a99 - added missing include to gl_walls.cpp 2016-02-10 20:49:06 +01:00

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

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.

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.

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.
