Hypertextures

Back in 1989 professor Ken Perlin invented the concept of hypertextures: A way of procedurally defining the volume of objects. This can be used to easily create 3D models with irregular surfaces, something that is more difficult with conventional modelling methods.

Below object for instance has density one for all x²+y²+z² < 1 + a small noise function, and zero elsewhere.




As hypertextures describe 3d models by their volume, it is easy to combine them with other volumetric data, like the result from an MRI scan.




The hypertexure technique can also be applied to add a complex 3D texture to an object consisting of polygons.
