Some RW info (PS2)

Ниже немного полезной (по крайней мере, для меня) инфы по RW PS2.

Некоторые особенности Texture Native:

Тут кое-какие выдержки из SDK:
RwRasterFormat is a set of values and flags which may be combined to specify a raster format. The format chosen for a particular raster depends on the hardware device and the raster type specified at creation time (see API function \ref RwRasterCreate). The format may be retrieved using API function \ref RwRasterGetFormat. The raster format is a packed set of bits which contains the following four pieces of information (these may be combined with bitwise OR):-
  1. The pixel color format corresponding to one of the following values:- This value may be masked out of the raster format using rwRASTERFORMATPIXELFORMATMASK.
  2. The palette depth if the raster is palettized:- In these cases, the color format refers to that of the palette.
  3. Flag rwRASTERFORMATMIPMAP. Set if the raster contains mipmap levels.
  4. Flag rwRASTERFORMATAUTOMIPMAP. Set if the mipmap levels were generated automatically by RenderWare.
