this adds a new --type (-t) parameter that is
used to specify cmgen’s output.
faces: outputs cube maps separate faces (default
and current behavior)
equirect: outputs an equirectangular image
ktx: outputs a ktx file
--format=ktx now implies —type=ktx
- internal cross storage is now always horizontal
and seamless.
- source cross images are now always converted to
internal format, conversion includes rescaling
and sampling if scaling down.
- vertical cross is supported again
- fixes#283
- replace hardcoded constants
- front and back labels where inverted:
+z is the front of the cube and -z is its back
when looking at the cube from the outside
with a camera pointing towards -z (and the cube
in front of it). This is the GL definition.
- make the synthetic uvXXX debug environment
colors match those of the debug environment
(except for -Z/back which is magenta instead
of black).
- add some documentation about skybox and cube map.
- cmgen now creates reflections maps for all input
assets by default instead of just for equirectangular
images.
- equirectangular decode doesn't mirror -- that's
done by the mirroring code now.
- mirroring can be turned of with --no-mirror
- option --mirror is gone
- faster mirroring code (do it before generating
mipmaps)
- added labels to faces of debug.png environment
- added a debug equirectangular image in third_party
