0726a88ab9 - only return DWORD aligned addresses in openings because the 3D floor code stores floating point values in there which cannot be accessed on platforms with strict alignment rules. 2016-05-11 12:04:41 +02:00

ac69ed3361 Minimal wallmost changes 
- Add comments
- Fixed: When WallMost() finds a line entirely above the screen, it should
  set the most array to 0, not -1.

a26d81e060 - fixed incomplete float conversion in R_RenderFakeWallRange. 2016-04-27 02:28:45 +02:00

0f99d7d73f - floatified the few remaining linedef and sector properties that still were fixed_t. The only fixed point things left in r_defs.h are the nodes and a fixed point setter function for vertex_t, which is still needed by the node builder. 2016-04-24 12:15:09 +02:00

31845cd16b - fixed two fixed/float mixups. 2016-04-24 10:24:43 +02:00

04e614daec - removed some fixed point functions that are no longer needed. 
- fixed: Visplane checks should only compare the plane flags that are relevant for rendering and mask out the rest.
- floatified FTransform and made the visplane checks a bit less verbose by moving the comparison as an operator into FTransform.

Note that this operator needs forceinline on Visual Studio so that it won't get called as a function.

35a6994d0a - remove the 'F' prefix from the floating point access function to the sidedef texture info, now that the fixed point versions are gone. 2016-04-23 10:55:55 +02:00

4d4f31fd83 - floatified sidedef texture info and fixed two bugs involving this data. 2016-04-23 09:41:59 +02:00

9a07f81269 - renamed all ZatPoint variants that return a fixed point value to ZatPointFixed, to avoid accidental mixup with the floating point variants. 2016-04-02 20:45:32 +02:00
Christoph Oelckers
66929cbaff - floatified p_trace, p_slopes and p_udmf.cpp. 
- major cleanup of unused code.

77f2530236 - floatified the sector plane movers and removed some of the ZatPoint conversion cruft. 2016-03-30 09:41:46 +02:00

25f5e8449a - replaced all direct access to sector plane coefficients with wrapper functions. 2016-03-29 12:40:41 +02:00
Christoph Oelckers
c7ae4688a3 - replaced all direct access to vertex coordinates with wrapper functions. 
So that code replacement can be done piece by piece and not all at once.

0c39bdd04c - floatified texture scale values. 2016-03-26 13:37:44 +01:00

4e60ea0252 - made AActor::alpha a floating point value 
- replaced some uses of FRACUNIT with OPAQUE when it was about translucency.
- simplified some overly complicated translucency multiplications in the SBARINFO code.

48b6b6e057 Clip portals to viewheight, not screen height 
- Aside, but is this even neccessary? The arrays being copied from should
  already be clipped properly.

7242a0ef94 - fixed: Rendering 2-sided walls with 3D floor light effects had the 'is3dfloor' flag of GetLightLevel inverted. 2016-02-29 10:26:07 +01:00
Christoph Oelckers
02d7572343 - some header dependency cleanup so that it is no longer needed to include portal.h to get the inline functions. Portal.h has been reduced of most dependencies now so that including it is cheap and can be done in other headers. 
- some consolidation in p_map.cpp. PIT_CheckLine and PIT_FindFloorCeiling had quite a bit of redundancy which has been merged.
- čontinued work on FMultiBlockLinesIterator. It's still not completely finished.

3ad2e4191d Remove fudging from the end of (O)WallMost 
- This might have been added in an effort to fix problems caused by mixing inclusive
  and exclusive right edges. It might not be needed anymore. Let's find out...

a85a8c1465 - changed mirror handling so that it works without attaching a portal to the mirror line and removed line_t::portal_mirror member. 
- did some cleanup on the portal interface on linedefs: All checks should go through isLinePortal (gameplay related) and isVisualPortal (renderer related) which then can decide on the actual data what to return.
- removed portal_passive because it won't survive the upcoming refactoring.
- removed all direct access to portal members of line_t.
- always use the precise (and fast) version of P_PointOnLineSide inside the renderer.

1d0a3d19c8 Fix a part in maskwallscan that was missed for right-edge exclusivity 2016-01-31 20:45:37 -06:00
Randy Heit
240ca2af4c Use consistant right-edge rules in the renderer. 
- The original Doom renderer was inclusive for all right edges. This was
  fine for the wonky projection it did. This was not fine for a standard
  perspective divide, so I had to change walls to be right-edge exclusive
  when I changed the projection. I only touched what was needed. Until
  now. The right edge is always exclusive now, which should prevent any
  more bugs related to mixing the two clusivities incorrectly.

a41dc24086 - fixed: 3D lights should override the sidedef's regular light completely, that includes relative light added by UDMF's 'light' property. 
- Renamed the 'noabsolute' parameter in side_t::GetLightLevel to 'is3dlight', what it actually is, to avoid the confusion that caused the abovementioned error.
- fixed: The Down2Up render path for sides of 3D floors had the 'is3dlight' check inverted.

15b97c1409 Fix scaling of 3D floor wall textures. 
The scale factors are now taken from the same part of the sidedef that
provides the texture.

8fa9aa2627 Use the correct sidedef's middle scaling when drawing 3D floors. 
This wants `curline->sidedef`, which is the 3D sidedef currently being
drawn.  `sidedef` appears to be the last regular sidedef that happened
to be drawn?  The perils of globals.

e1ee80661e Make FWallCoords' members lowercase 
because they're kind of a pain to type when all uppercase.
- Also, make its sx1 and sx2 members shorts, so it takes less space, since
  it's getting crammed into a vissprite now.
