This paper presents the experiences in programming about the editing of graphics andthe solving results of geometric intersection, such as the reflection rotation and translation ofgraphics, the most of ten used nine solving results about the geometric intersection during in-teractive drawing, It is also to explain the principle and methods with C routine in examples.

Compounded geometry image representation of point cloud surfaces and its application;

An adaptive curvature simplification method for point-sampled model is presented based on geometry images.

Geometry image is the result of converting the space geometry information totradition images.

On Kant,Husserl and Wittgenstein s Approaches to the Philosophical Thought of Geometric Figure;

Finally the paper shows the realization of algorithm by vc++ language,which can recognise the regular geometric figure in the computer using this program.

This paper defines fuzzy sets, researches some problems of fuzzy mathematic and discusses the subjects of geometric figure with the concept of convex sets.
