gm-matthew 3cf8a1fa94 Implementing texture NP values
For some reason Model 3 uses vertex coordinates rather than texel coordinates to calculate mipmap levels
Revised microtexture implementation; results are very close to real hardware when running at native resolution with supersampling disabled

Ian Curtis 8778f98c4a Add missing edge on transluency function 2023-11-17 15:50:04 +00:00
Matthew Daniels 9ffce8b92a Getting rid of most of the includes from Supermodel.h; each file now explicitly includes the header files it needs.
Making changes to a header file should no longer force the entire project to recompile.

Ian Curtis bf4d725970 Smooth texture repeat makes no sense for alpha/contour textures with pixel dilate. HW seems to treat them as non smooth anyway. Also implement some line of sight stuff, used by Scud. Really need to check the threading/synchronisation of the register reads but it basically works. 2018-10-19 20:59:46 +00:00

Ian Curtis 3c78571615 There are 2 bits in the polyheader labelled discard. When both are set ie in sega rally, the polygons are totally discarded. Scud seems to set bit 1 which seems halve the opacity. 2017-04-15 19:00:46 +00:00
Ian Curtis edfb521a9b Daytona seems to use this completely undocumented feature of the real3d pro-1000, the ability to invert texture colours. This patch fixes the colours on the cars, and the signs which should flash by alternating their colours. 2017-04-05 17:57:38 +00:00
Ian Curtis 2ae2010ee4 Add high priority poly function. Used by harley. 2017-02-18 23:58:08 +00:00
Ian Curtis 4a116190b5 When the translator map?? bit is enabled the colour format seems to be 4-5bit. Max observed value is 16. Scaling these values up seems to produce the correct colours in harley and dirt devils. 2017-02-16 17:20:42 +00:00
Ian Curtis 2c23268d88 Support microtexture relative scale. The exact scaling values are not known, but a 2x difference between each level seems highly likely. We know from visual inspection from scud that the first level is exactly 4. The SDK has a function that accepts a float input for scale and does this. lod = (1/scale) + 0.5. If lod>3 lod = 3. So this is our best guess. 2016-12-09 14:13:46 +00:00
Ian Curtis c3581c9fe8 Support multiple microTextures, fixes crazy texturing in sega ski champ. I'm assuming microtextures are always located on the other memory bank to the base texture. This logic seems to work for all our games anyway. 2016-10-06 01:37:29 +00:00

Ian Curtis 661f19be19 fix transparency values, values are from 0-32, not 0-16 where the top bit disables 2016-05-27 22:20:57 +00:00
Ian Curtis 2086b1c9af Stencil layered polys, fixes shadow z fighting in some of the games. Other games maybe using stipple alpha (yuck), not sure yet. 2016-05-27 19:30:40 +00:00

Ian Curtis c7412828d4 Use proper texture wrapping mode for 2d. Stops garbage down the top and left sides. Should really use NPOT texture. 2016-04-02 12:23:46 +00:00
