摘要
应用Pro/E良好的兼容性,通过其接口输出虚拟环境所需的三角面片模型和运用近似凸集分解算法将该三角面片模型转换成凸包模型,生成的凸包模型较之三角面片模型外形更粗糙,数据量程更短,经仿真计算凸包模型较之三角面片模型运算时间更短,所以应选择不同的触觉模型来满足针对虚拟环境中模型对实时性和精确性的不同要求。
Being favored by the good adaptability of Pro/E and application of its interfaces,the virtual environment that required tri-angle models were obtained and then,transformed into convex models with the approximate convex decomposi-tion algorithms.The convex models,compared with tri-angle models,maintain less data amount while rougher surface.The time consumption in convex models calculation was more thrift,which meant that different touching models would be ac-quired to achieve corresponding requirements of real-time performance and accuracy in virtual environment.
