e7d73fd8e7 - fixed clipping code. 
This seems to require the old code as-is - the latest refactoring broke some stuff again and had to be reverted.

1dfb2672a8 - flat sprite rendering! 2021-03-26 20:28:44 +01:00

fd0e9824b6 - call the game specific analyzesprites functions. 2021-03-26 15:06:14 +01:00

0b1e81023f - added sprite collection loop to ProcessSector and did a bit of cleanup on the TSprite code. 2021-03-25 23:16:32 +01:00

af54cf3a3c - made SW's sector portals operational. 
Unlike the other games these are so poorly defined that the engine has to rely on the original fudging to pick the proper portal to link to. As a result they are just as limited as they always were.
In addition all the portal search code had to be reinstated.

957f7e9487 - Accept binangle, fixedhoriz and lookangle classes in SetupViewpoint() vs. Q16.16 variables. 
* Allows for more precision than Q16.16.
* Used as opportunity for `rollang` to be set using the `asdeg()` method, not `asbuildf()`.

463dbc4c4f - fixed issue with empty voxel slots. 2021-03-25 08:37:44 +01:00
Christoph Oelckers
368b2319f2 - replaced 'static FORCE_INLINE' globally with 'inline'. 
I have no idea what kind of compiler needs such a construct, it's totally not how C++ should be written.

b7e8815133 - some further lightening of compat.h. 2021-03-24 21:13:36 +01:00

8993095bc0 - got rid of pow2char 2021-03-24 20:37:20 +01:00
Christoph Oelckers
d8627a2b3f - removed all remains of projection math weirdness from the automap code in the games plus a bit more cleanup of the engine code. 2021-03-24 20:28:58 +01:00
Christoph Oelckers
022edd2dc2 - cleaned engine.cpp off all code exclusive to the Polymost renderer. 2021-03-24 19:45:42 +01:00
Christoph Oelckers
0c7f05a416 - let the clipper work exclusively on Build coordinates. 2021-03-22 23:40:25 +01:00

63f057d93f - portal and sky WIP. 2021-03-21 22:48:01 +01:00
Christoph Oelckers
09a9e14feb - set up engine portals for SW. 
Also moving more code to _polymost.cpp which is only needed for ad-hoc lookup of portals with a client side implementation of a two-layer renderer.

a36377111c - engine-side portal setup for Blood and RRRA. 2021-03-21 14:48:35 +01:00

d42ce0ee7e - WIP 2021-03-20 23:01:16 +01:00

f30a568858 - moved wallfront function into polymost.cpp. 
This was one of the few functions left in engine.cpp that accesses the global scene state.

91957e40f1 - moved some original Raze code out if the Build folder. 2021-03-20 17:08:55 +01:00

fedfc2cfa4 - removed global variables that were only being used by the automap drawer plus a few other obsolete things. 2021-03-20 16:46:06 +01:00
Christoph Oelckers
30f4e2b29d - replaced the engine automap drawer with one leveraging the newly added sector geometry data. 
This eliminates a lot of code depending on Build's projection math.
 2021-03-20 16:20:48 +01:00
Christoph Oelckers
3df5c440f9 - added some helpers to make it easier to determine if a sector's geometry has been altered. 
Walls had no sector reference so this was added for marking the sector as altered when a vertex gets dragged around.

a5b3a1dd3e - removed some unused things from engine.cpp. 2021-03-19 15:12:54 +01:00
Christoph Oelckers
76682c72e3 - removed krecipasm. 
Analyzing the results, this is not needed as its precision is virtually the same as floating point math, so its one use got replaced.

547ed4e415 - route everything through the full backend, now completely bypassing the intermediate GLInstance layer. 2021-03-18 17:18:03 +01:00
Christoph Oelckers
4cf2493cfd set up the entry point for the renderer. 2021-03-18 14:49:36 +01:00
Christoph Oelckers
e9dd1c104b - started adding the draw list code from GZDoom. 2021-03-18 10:19:13 +01:00
Christoph Oelckers
2d958745b4 - fixed: Polymost must set the viewpoint if renderers are switched. 
- fixed coordinate order in renderSetViewpoint
- fixed backwall checks accidentally testing wall 0 instead of the current wall.

65097c4098 - set proper visibility factor and viewport. 2021-03-17 19:07:00 +01:00
Christoph Oelckers
b492cbcebb - ported my old Build-style renderer for Doom from 2008 and the wall renderer from GZDoom to work with Build data. 
It renders walls, but y-panning is still broken.
 2021-03-17 16:54:36 +01:00
Christoph Oelckers
9ebd8fd4a5 - put all of Polymost in a namespace. 
So that its static variables are properly separated from the rest.

a484e39e05 - removed integer square root code. 
On modern systems using the sqrt function with a cast to int has no relevant performance disadvantage anymore so there's no need for all of this.

ac82838859 - removed unused 'wallvisible' function. 2021-03-15 18:58:14 +01:00
Christoph Oelckers
8aa59f2385 - use clamp instead of bit masking to handle out of range interpolation factors for models. 2021-03-15 11:35:39 +01:00
Christoph Oelckers
ad8654ed06 - fixed maphack loader. 
The duplicate 'currentSprite' variable prevented it from doing anything.
Also cleaned up the interface a bit to avoid using a global variable for parameter passing.

Fixes #279
