Building Asteroids

Posted on: April 7, 2009

Using 3 dimensional mid-point displacement (diamond-square) to create asteroids out of spheres:

astsu4it1000el26

Subdivisions: 4
Elevation: 26
Iterations: 1000

astsu4it500el26

Subdivisions: 4
Elevation: 26
Iterations: 500

astsu4it500el63

Subdivisions: 4
Elevation: 63
Iterations: 500

Midpoint displacement can be slow depending on the resolution(subdiv) and the number of iterations, but for the quick generation of low-poly asteroid shapes it is an easy to implement, viable model. :)

Update:

planet

Of course planets are possible too, but they require a much higher degree of detail…
