现有曲面 meaning in English

existing surface

We use bezier - shaped displacement reference curves to determine the new position of the vertices on the deforming surfaces . the proposed approach is fast and robust , and can support real - time interactive mesh editing and handle arbitrary meshes thanks to re - sampling and subdivision operations
这种变形方法计算快速便捷，可以方便地集成到现有曲面造型系统中，结合重新采样以及曲面细分等技术，这种曲面造型方法可以应用在任意拓扑结构的网格曲面编浙江大学硕士学位论文摘要辑上。
