Abstract:Most of the traditional constrained texture mapping methods meet the specified constrained conditions at the cost of sacrificing the parameterization's conformality. In this paper, a new adaptive constrained texture mapping method is proposed. The constrained parameterizations are computed through iteratively minimizing a weighted energy covering both conformal term and constraint term. In order to make them in balance, the weights in the energy are updated step by step. In one iteration step, the weight of each constrained vertex is dependent on a monotone function of the distance from current position of the vertex to its specified location. By this method, the conformality can be well preserved while the constrained conditions are satisfied. Experimental results show that a good texture mapping can be taken quickly and effectively.
