Consider a simple cube as
superellipsoid{ <.25,0.25>
texture{ pigment{ color rgb<0.65,1,0.1>}
finish { phong 1}
}
I put an image on its surface as
superellipsoid{ <.25,0.25>
texture{ pigment{
image_map{ png "ad.png"
map_type 0
interpolate 2
once
}
}
finish { phong 1}
}
}
I have two problems:
1. How can I keep the pigment color underneath to have a closed where has not
been wrapped by the image?
2. Wrapping starts from the left corner of the object, and I lose the curvature
on the left side, but it is OK on the right side. According to
http://www.f-lohmueller.de/pov_tut/backgrnd/p_sky9.htm the image covers +Z and
goes to +X. Is it possible to put the image on the center of +Z to let the
excess image covers both -X and +X?
