| Summary: | Many applications in computer graphics require complex, highly detailed models. However, the level of detail actually necessary may vary considerably. A simplified model can save up much memory and enhance the rendering speed. Throughout years, different mesh simplification algorithms are been developed. QSlim is one of the best mesh simplification software currently.We developed some novel methods that set constrains on the original QSlim algorithm so that the new software can preserve the geometrical symmetry property from the original model after simplification. Our algorithm collects symmetry edge pairs, modifies their contraction targets and contraction sequences, and tries to add penalties to axis edges to avoid asymmetrical results. The simplified models from our program can preserve most of the detected symmetry edge pairs. |
