Popis: | In order to keep the geometric shape and texture of the model in the process of model simplification, this paper proposes a simplification algorithm based on feature preserved for model with texture. By finding the feature points and odd points of the model controlling the point selection to collapse edge for simplifying model. Angle between normal vectors of the edges two vertices and the area of the triangles adjacent to the edge are introduced in the QEM algorithm as the error factor to redefine the cost of edge collapse, finally better keep the feature of model. This paper uses Mipmap technology to generate multi-resolution texture maps so that improves the efficiency when rendering model in real time. |
