CubeMapGen

CubeMapGen is a tool for importing, filtering, visualizing, and exporting cubemaps.

Cubemaps can be assembled from separate face images that can be loaded into each cubemap face and interactively flipped vertically,
horizontally, and diagonally in order to align the faces.

Angular extent filtering and edge seam fixup provides new high quality filtering results for prefiltered environment mapping, and cubemap mipchain generation.
