Abstract

In this technical report, two different methods for calculating the distance between a point and a triangle in 3D space will be described. It will be shown that it is far more efficient to calculate the distance by using a rotation to make the problem 2D. Both methods are tested with relation to the production of 3D data from polygonal meshes  (voxelisation).
