Texture mapping adds visual details to enhance realism of three-dimensional model. For most area in computer graphics, it is important to ensure the correspondence of the texture details with the features of the model. Therefore, there is a need of software to perform such task. In this project, our challenge is to map a two-dimensional texture into a three-dimensional model based on user-defined constraints in position for some features. We propose a solution by flattening the model into two-dimensional first, and then applying transformation to a texture image such that it will fit into the flattened model. Some investigations on the state-of-the-art techniques and algorithms used for model flattening and image warping had been done. Subsequently, we built our FLATTENING and WARPING program using C++ programming language for experimental purpose. Our proposed method works with a human face of size 3614 polygon counts in approximately 2 minutes. We managed to achieve average error rate of 0.226873 distance units per vertex with no overlapping terms. From the result, it can be concluded that the algorithms used in our method produce a good performance. Therefore, the proposed method is suitable for texture mapping with constraints in features location.
