[0028] Below in conjunction with specific embodiment, further illustrate the present invention, should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various equivalent forms of the present invention All modifications fall within the scope defined by the appended claims of the present application.
[0029] A triangular grid simplification method based on angle error measurement, comprising the following steps:
[0030] Step 1: Input the original model that needs to be simplified, and pre-classify the triangles in the model. The triangle network is divided into internal triangles and boundary triangles, and the boundary triangles are further divided into vertex boundary triangles and edge boundary triangles. Determine the type of triangle by judging whether the vertex is a boundary point. If ...
