966e6797e4 - fixed: The view path for checking whether the player sprite should be drawn during a portal transition was never set properly in the portal transitioning case. 2016-05-09 23:16:06 +02:00

8f3921190f Keep values in floats longer for visplane drawing 2016-04-28 21:21:49 -05:00

af2a1769d8 - use the FP2005 method to calculate xtoviewangle, because it is far more straightforward than the old version. 2016-04-28 16:27:28 +02:00
Christoph Oelckers
ef98757c7c - replaced finesine for texture warping with a smaller custom table, based on the old 2005 FP code, but fixes the generation of the sine table. 
- removed all remnants of finesine and deleted tables.c and tables.h.

027b8d29b8 - make FieldOfView a real angle and remove all uses of finetangent. 2016-04-28 13:59:06 +02:00
Christoph Oelckers
f301cf7c57 - don't use finetangent for generating xviewtoangle. 2016-04-28 13:03:48 +02:00

26f54b0ba4 - eliminated tantoangle and cleaned up r_tables.h 2016-04-28 12:18:33 +02:00

44adff459a Remove halfviewwidth 
- Why I thought I needed this variable in addition to centerx has
  long ago left my memory.

afa3009f93 - Fixed a GCC/Clang compiler error and a warning. 2016-04-21 16:11:03 +02:00

082042818b - refactored sector portal data so that it does not rely on actors. 
This is necessary because otherwise the level data cannot be serialized before the actors.

d88a5ac353 - make distancecheck 3D and use the actual view position for calculation. 2016-04-13 10:48:39 +02:00
Christoph Oelckers
db86385cf6 - removed STACK_ARGS. 
The only reason this even existed was that ZDoom's original VC projects used __fastcall. The CMake generated project do not, they stick to __cdecl.
Since no performance gain can be seen by using __fastcall the best course of action is to just remove all traces of it from the source and forget that it ever existed.

0cbdb9ab72 - handle display of player sprite during portal transition properly. 
This checks if the current viewpoint lies on the interpolation path, translated by all active portals.
 2016-04-07 19:35:01 +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
bb13590e07 - make viewx etc. global. 
- a few minor optimizations.
 2016-04-02 20:07:02 +02:00

8680391e0b - floatified the global view variables. 
The software renderer still uses internal copies of the fixed point version.
 2016-04-01 12:22:16 +02:00

9412ce45d6 - floatified portals.cpp and most of p_maputl.cpp. 2016-03-31 16:52:25 +02:00
Christoph Oelckers
ff0b371582 - made the linedef deltas private and only accessible through access functions. 
Now everything should be in place to remove the fixed point math from the rest of the play code.
 2016-03-29 16:13:16 +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.

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

97821a3036 21:9 aspect ratio support 
- vid_aspect 6 forces 21:9

14a0567343 - optimized the portal translation functions by precalculating the rotation angle, sine and cosine. 2016-03-03 11:58:04 +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.
 2016-02-11 21:33:30 +01:00
Christoph Oelckers
00895c245e - mpved all software renderer specific code for the portals into the render sources. 2016-02-05 15:39:06 +01:00

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.

605fce9008 Fixed skybox clipping: things in a skybox shouldn't be clipped against current portal. Fixed: portal inside of a skybox sets CurrentPortalInSkybox to false. 2016-01-10 05:45:26 +02:00

4d518a220c Fixed skybox clipping: lines in a skybox shouldn't be clipped against current portal 2016-01-10 05:22:33 +02:00

7e87216878 - fixed: r_visibility values >= 205 appear to cause fixed point overflows at least on 5:4 aspect ratio so they should be blocked. 2015-11-27 10:44:37 +01:00

891b3da103 Remove extra magnitude from magic texture mapping values 
- These used to be fixed point, but now they're floating point, so the
  excess magnitude is unneeded.

bbc3b69a7c Remove polymost stuff 
- Maybe it will be back someday, but it's been essentially dead for nearly
  10 years, so don't hold your breath.

d8ff4ec281 - Fixed: All clang 5.0 warnings. 
- Renamed autostart/autozend since Xcode’s build process links in strictly alphabetical order.

50c5dc62aa - fixed typo in USDF spec.

- division by zero check in R_SetVisibility from GZDoom.

118e513d03 - Fixed: The player's position was only predicted during the duration of R_SetupFrame(). 
Consequently, if somebody used the chasecam while predicting, they would appear to lag
  behind the camera, because their actor would be at its unpredicted position by the time
  sprites were processed.
