A novel simplification algorithm based on vertex clustering was proposed in this paper.The simplification quality was improved by using Quadric Error Metrics to compute the placement of each clusters representative vertex. Based on the analysis for the particularity of texture mapping of cultural relic model
the appropriate mapping method was proposed
the mapping relations for geometric model and texture image was established
and the texture mapping of the three-dimensional model composed of the non-parameterized surfaces was realized.These processes enable the model photo-realistic.
