79823b430c - reinstate the old code for rendering the first portal without stencil
The previous commit fixes the true issue causing the problems - with this back the restriction is not needed anymore.

b644000b02 - fixed texture y-flipping on bottom tiers of walls.
The flip flag was taken from the wrong side of the wall.

29b0106a96 - fixed yet another problem with the local 'sprite' variables in HWWall causing problems.
This variable and its companions in HWFlat and HWSprite have now been renamed to avoid these issues.

d8b808576f - restrict the sky portal shortcut to skies in scenes where there are no other portals.
This entire setup does not work with sector portals, causing various render glitches in Shadow Warrior's portals. This also applies to skies within portals so it is now restricted to single sky setups.

389340f97c - use sections for rendering. 2021-05-03 00:15:09 +02:00
Christoph Oelckers
30b1b046e4 - added an intermediate data structure to decouple the rendering from the immediate map data.
This will be needed for sectors consisting of disjoint parts and for providing some help with addressing rendering anomalies

ad28630df6 - offloaded map patches to data files.
This is a lot easier to manage than having them in the code.
For now it piggybacks on the map hack feature, later this should use the same scripted approach as GZDoom.

a7046eaee4 - fixed animations on skies.
Lunatic Fringe made this very obvious.

5585351c0f - added a hack to help the new renderer with Lunatic Fringe.
This is by no means a permanent solution but having it buys some time to find something more universal that won't affect performance too badly and investigate the need for a more robust solution.
The idea here is to define pairs of walls where when the first element of the pair is seen, it will treat the second one as view blocking.
This is used as the two offending windows (sectors 151 and 152) to cope with the lack of a height sensitive clipper.

be08a2f800 - clipper rework
* let the clipper work on relative angles to simplify the math.
* properly initialize the initial visible range and preserve it for multiple invocations.
* track the maximum visible angular range per sector. While possibly not sufficient to handle every edge case imaginable it has low overhead and is still useful to eliminate obvious cases that do not need more complex checks. It is enough to fix the blue door in Duke E3L4.
* removed unused elements of the clipper.

eb573bea23 - removed all compensation for the clamped shades.
None of this is needed, the shader can work with out of range shades to produce proper lighting.

Christoph Oelckers
dc0df7d081 - don't clamp shade values in the setup pass.
We need their proper values when setting up the lighting.

643b969dff - added another weird Build specialty: no vertical sprite offset flipping for face sprites.
Just... why...? :?

be20b6a839 - fixed: wall sprites do not need NPOT emulation. 2021-04-20 16:58:18 +02:00

d078b511b8 - flip backwards oriented wall sprites before submitting them to the render list.
Backwards orientation will break the translucent object sorter so this needs to be sorted out beforehand.

ccdf9d13f1 - do not render sprites that are extremely close to the camera.
These can temorarily cover the entire screen so everything with a distance of less than 4 map units will now be skipped if it is a face sprite.

cdf89b9175 - portal rendering fix when viewing through two-sided walls outside the actual portal area.
If there's more portal area behind such a line its range in the clipper needs to be cleared again.

f83e678ea0 - use the smooth ratio from the game logic in the renderer instead of calling I_GetTimeFrac again.
Unlike the higher level code this does not check for game over conditions.

f254eeb465 - binaryangle.h: Remove lookangle class and replace use with binangle.
* Added in fca846272e to deal with signed adjustments but its just not needed.
* Made better use of `binangle`/`fixedhoriz` class getters and setters than before as well.

057b8a7354 - cleanup of bvectan family of functions.
This can be greatly simplified to a single bvectangbam function using atan2 directly.

28fb752446 - Replace gethiq16angle() with bvectangbam() in renderer code. This addresses some observed clipping issues in the new renderer. 2021-04-10 09:23:02 +10:00

e0dc261dfd - fixed edge case in wall sorter when the camera is exactly on a line that's being checked. 2021-04-10 00:05:29 +02:00

345275db5d - better handling for portal lines having sloped back sectors.
This is a very ugly special case that probably needs a bit more work to get right, for now this should be enough as this combination is rather rare.

38ecfc8fa5 - added handling for cubemapped skyboxes. 2021-04-08 12:47:31 +02:00

b68512ef88 - on closer inspection, do not draw skies on intra-sky lines ever - the renderer already takes care of this elsewhere. 2021-04-08 10:10:15 +02:00
Christoph Oelckers
d348377bd8 - when drawing skies on walls where both sides are sky, use the backside's texture.
This fixes a sky anomaly in RR's E1L1.

7a03967ceb - fixed clipping info not properly reset when rendering the scene in two passes.
We need to reset the gotsector array for that, but since we also need the accumulate result of both passes there's now two such arrays.

4bd44f9d62 - flat sprites use different visibility rules.
Hooray, Build engine, yet another totally nonsensical magic factor with absolutely no reason why...

6ad0089524 - fixed flat sprites using the sector bit names for checking for being flipped.
Thank you, autocompletion... :(

59f18f5fa7 - ensure that all HWSprites are oriented with z1 > z2.
This is required by the sorting code to work as intended.

f9f1d591b3 - must set up fog before textures.
Otherwise the PickTexture callback won't get all needed info.

3d846f341a - fixed a major clipping issue with the new renderer.
* the bunch drawer can at most process an angular range of 180°. If this gets exceeded it can run into wraparound issues that may cause holes in the geometry.
* there was no clipping to the current field of view so it always checked the full 360°.

d823ae255e - fixed view clipping for portal sectors.
All lines within the portal must neither be added to the clipper nor checked for obstruction by other parts of the map.
