Hi,

I've recently compiled a small program that generates a sphere made of
triangles which's surface is modified to create an earth-like texture.
This produces a triangle mesh of a planet.

So, does anyone think that this is in any way useful? Because you could
probably do the same by creating a texture on a sphere, then rendering
it with a cylindrical camera and using is as a height-field and pass it
through John Beale's orb program.

If anyone thinks it might be useful I might add craters and such.

Guy

Can this program be use to generate other surface profiles
or were you only concerned with earths topography ?

If I used a larger extrusion amount and added some craters and used a
solid color (instead of using blue for the sea in the lower areas) it
could easily be an asteroid. At least so I would like to believe.
