8680391e0b - floatified the global view variables.
The software renderer still uses internal copies of the fixed point version.

8fd76f0c8a - floatified bmaporgx and bmaporgy, allowing to remove the gross overflow prevention hacks present in the blockmap code. 2016-03-31 09:23:14 +02:00

1125101b37 - floatified AActor::Prev plus the stuff using it.
- rewrote some coordinate functions in AActor to use real float math instead of converting back and forth between float and fixed.

3a598d672e - removed the angle_t type from the VM, now that nothing in the interface requires it anymore. 2016-03-25 14:55:01 +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.

51b05d331d - replaced AActor::vel and player_t::Vel with a floating point version.
- Converted P_MovePlayer and all associated variables to floating point because this wasn't working well with a mixture between float and fixed.

Like the angle commit this has just been patched up to compile, the bulk of work is yet to be done.

671291227e - first stage of converting actor angles to float complete
Patched up everything so that it compiles without errors again. This only addresses code related to some compile error. A large portion of the angle code still uses angle_t and converts back and forth.

e11a0986ce - encountered a strange crash that after changing a map, InSubsector was not NULL and pointing to invalid data. So let's better NULL this variable explicitly each time a render loop is started. 2016-03-08 12:27:01 +01:00

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.

158caf78a0 - more float to double conversion.
In particular this removes all assignments of FIXED2FLOAT to double variables because they not only lose precision but also generate unnecessary code.

6d0ef7a9da - added conversion macros to convert floating point angles to angle_t, using xs_Float.h, and replaced all occurences in the code with them (let's hope I found everything.)
Converting a floating point value that is out of range for a signed integer will result in 0x80000000 with SSE math, which is used exclusively for this purpose on modern Visual C++ compilers, so this cannot be used anywhere.
On ARM there's problems with float to unsigned int conversions.

xs_Float does not depend on these

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.

75d21d6dd8 ZDoom wasn't setting drawseg_t::curline when making "fake" drawseg for skyboxes, which interfered with portal sprite clipping routine randomly. 2015-11-12 01:17:03 +02:00

5f43e5b4ea Don't use finesine table when offseting for plane rotation
- This table isn't precise enough, so the result is noticeably off if
  you're far enough from the origin.

43fe317dbe Use flexible array members for structs that end with var-sized arrays
- Since Clang++, G++, and VC++ all support this extension (even though it's
  technically officially only part of C99), use it. It lets Clang's array-
  bounds checker know that these are meant to be accessed out of their so-called
  "bounds".

e9be49f37d - fixed: R_DeinitPlanes did not free all visplanes because it called R_ClearPlanes with 'fullclear' set to false.
- removed some redundancy from R_ClearPlanes.

a50e670c0c - Use tests less prone to overflow on very steep slopes when detecting which side of a plane
the camera is on. Mostly, this means testing the distance of the camera to the plane rather
  than computing the plane's Z at the camera and comparing that with the camera's Z.

9acf65b9a4 - Added support for a PALVERS lump. This specifies replacement textures to
be used when for walls and floors when the renderer is paletted. The format
  is very simple:
    rgbtex1 paltex1
    rgbtex2 paltex2
    ...
  The first texture is the one to be used normally, and the second is the one
  to be used in paletted modes.

  The vid_nopalsubstitutions cvar can be used to ignore this lump.

3401e92834 - Emulate the size limit of Doom's lightscale table by capping the value of vis passed to
GETPALOOKUP. The end result is that there is a minimum distance around you where light
  amplification stops and it gets no brighter. Should this scale with visibility? I can't say.

  So, yeah, it turns out all these years ago, I made this out to be harder than it really is.

1806e47e43 - fixed: Sector_SetLink did incorrect checks for the returned control sector
- added Sector_SetTranslucent special so set translucency of portal planes at run time.
- added 'additive' information for portal planes. This is no-op at the moment because the flat drawers can't handle additive translucency yet though.

e46183d836 - removed all portal fudging that was necessary to make thing based portals work the same as line based portals. Using an actor flag on the skybox thing the visplane code now checks what kind of portal is used and uses the proper logic accordingly. As a result the "Portals" compatibility flag no longer exists.
