Abstract
The invention is directed to rendering a three-dimensional view of a workpiece shape based on a point set using a normal vector representation. The distribution of the normal vectors can be analyzed by a centered view of the normal vectors, which can be done manually and/or automatically. These structures give a first indication of the surface quality. In addition to the centered representation, the normal vectors can also be directly overlaid on the path, which facilitates the determination of local flaws. In addition, a pseudo-surface view can be generated based on the position of the normal vectors.

A method for rendering and/or evaluating a quality of a workpiece surface based on CNC program data for a machining operation, the CNC program data including a set of points defining a surface in space, with the set of points including path points describing a space curve, comprising the steps of:
- determining and rendering associated normal vectors for a plurality of adjacent path points;
- indicating surface regions having a high surface quality by normal vectors pointing in a substantially identical direction;
- and
- indicating surface regions having flaws by normal vectors pointing in different directions.
