Abstract: In a programming method, a dimension system relating to a product can be embedded into a programming system. The dimension system includes measurement dimensions of measuring points of the product, and the serial numbers preset for the dimensions. The method arranges the serial numbers according to a predefined measuring path, and stores the serial numbers into a dimension list according to the order of the serial numbers presented in the measuring path. After importing the dimensions of the serial numbers into the programming system according to the presented order, the method converts each of the dimensions into a series of codes, and generates a measurement program for the dimensions according to the codes.

Abstract: In a method for displaying a three-dimensional object, a pixel value matrix and a projection depth matrix are created, coordinates of the object are read according to a B-spline curve, and a triangle mesh model is created according to the coordinates. A triangle is selected from the triangle mesh model one by one, so as to obtain coordinates of vertexes of the selected triangle, convert the coordinates of the vertexes to two-dimensional, and generate a figure according to the two-dimensional coordinates. A projection depth of the selected triangle is computed and colors of the selected triangle are added to the figure if the computed projection depth is less than a corresponding projection depth recorded in the projection depth matrix. The pixel value matrix and the projection depth matrix are updated and a two-dimension image formed by elements of two matrixes is outputted onto a display screen.

Abstract: In a programming method, a number of points measured on a product are roughly fitted into/matched with one or more geometrical elements, and a fitting value of the geometrical elements are output to a first data list. The method records the storing positions of the geometrical elements having fitting values that are within a predetermined tolerance value in a second data list, and obtains a best geometrical element type of the product by determining geometrical element types that correspond to each of the storing positions recorded in the second data list using a matching condition. After the best geometrical element type from the first data list is obtained, the method generates a measurement program and displays the measurement program on a display device.
