The orientation distribution of fibres is relevant to the properties of a number of different kinds of fibrous materials from many fields like biology and engineering, including short fibre reinforced composites. The Persistence of Vision Raytracer (PoV-Ray) is a program for creating photorealistic images using raytracing. We discuss a sort of creative misuse of this program in science, because it was originally developed as an artistic software. However, the ability to create virtual images of virtual parts, test the image recognition software that is used to measure the fibre orientation distribution, and compare the results with the known distibution is a huge step forward. In this article the focus is on slicing/photometry, but computed-tomography-like images or microscope images could be produced as well and used to test segmentation and skeletonization algorithms.
