Does anyone know of a package that can generate random noise in a 3D surface. I'd like to be able to apply a height map or a randomizer function to a 3D solid like I can to a terrain to create realistic bolders, quarried stones etc from simple shapes. Assigning a bump map looks OK except the edges are still square and smooth. Right now I'm limited to creating a mesh and fiddling with the points or doing the boulean union/difference in nurbs. A 3d heightmap that got the edges right or something that could randomise the location of each mesh point by X,Y,Z would be great. Do any programs do this?
