Abstract Modelling fruits by applying ellipsoidal parametric
equations and concave-convex texture and colour texture processing, we
realised the visualisation of different fruits. Creating surface
bumpiness by applying a perturbation function to the ellipsoidal
surface normal, we can simulate geometric shapes of different fruits.
Using basic functions to define colour and texture change, we can
simulate surface colour of different fruits. The key is to analyse the
relation of the fruit’s shape to the ellipsoid, and find perturbation
functions. The method is simple in that it consists of few different
elements, and they can be automatically changed. It is easy to
construct an exterior model, a growth model and a body model of virtual
fruits. This paper shows a few examples of building models of virtual
fruits.
