ABSTRACT:
The present invention is a method for visualizing a two dimensional field of orientation data on a surface which may be (flat or curved). A unit polyhedron is constructed which approximates a unit sphere centered at a point on the surface corresponding to the orientation vector. Colors are assigned to facets of the polyhedron such that adjacent facets have similar colors. Orientation vectors are projected onto facets of the polyhedron, and the surface point which is associated with the orientation vector is color coded with the color of the intersected facet. The method can be used in geology, metallurgy, stereology, and any other domain where a large set of orientation data is collected.
