Probably this should go to p.newusers, but I can't seem
to find anything in the manual.
I'm doing a simple moon - sphere, uv_mapping, image_map and bump_map:
#declare Luna = sphere {
0, 1
texture {
uv_mapping
pigment {
image_map {
jpeg "albedo.simp750.jpeg"
}
}
normal {
bump_map {
jpeg "moonbump4k.jpg"
bump_size 1.8
}
}
finish {
ambient VeryDarkBlue
diffuse 1.0
specular 0.1
roughness 0.35
}
}
rotate -90 * y
}
but that just doesn't cut it because at the terminator
the bump map just abruptly stops.
So I want to replace the sphere with either a height_field
(are spherical height fields possible? I can't find any
references) or an isosurface, using the bump map file as data.
I'm sure this question must have been asked a hundered
times before, so please excuse me if I've missed it,
but I can't seem to find anything relevant.
