Ian Curtis	ff8e9d6aad	Check for overflow. Fixes some fade effects	2016-05-30 23:10:56 +00:00
Bart Trzynadlowski	5c1a240565	New engine: expanded color indices to 12 bits from 11. Added PolygonHeader::ColorIndex and SensorColorIndex methods.	2016-05-28 20:49:10 +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	9e279a0c1f	Non luminous polygons seem to be effected by the lightModifier also. API seems to have no restriction in this regard, neither does the SDK. The ocean hunter requires this for some of the 2d stuff. Light modifier values only seem to exist between 0-16, which is strange for 5 bits of precision. Possibly top bit disables the effect and lower 4 bits are the value. This clearly differs from the SDK, but without this the values come out clearly wrong.	2016-05-16 10:49:00 +00:00
