Hi all:
I'm interested in figuring out a general algorithm for mapping
2D images onto adjacent triangles of geodesic surface (for different
frequency geodesics); rather than reinvent that wheel, is there an
algorithm (or better yet POV-Ray code) and/or a pre-processor to map a
2D image onto a portion of a geodesic surface? I'm guessing that the
general approach is to use a good 2D to spherical map with minimum
distortion, and then apply sphere to geodesic triangle mapping... Any
help with part or all of this would be appreciated! Ideally, I'd like
to be able to define the orientation, and scaling for a 2D
(rectangular) bitmap (e.g. jpg) file and then apply it to a geodesic
surface (specifying the frequency (using spherical subdivision of an
icosahedron) and render with POVray.
Thanks in advance! :-)
