摘要
自动地根据加工面的起伏情况,采用不同分辨率的三角片逼近曲面,从而大幅度地减少三角片总数,在保证仿真实时性的同时仍然保持很高的图像质量;而且可以进行平移、旋转和缩放等操作.当要评估加工误差,检查过切、欠切和干涉时,可以自动地切换到全分辨率模型,保证了这些检查的准确性和正确性.
The resolution of triangles to approximate machining surface is automatically updated according to its flatness, thus greatly reducing the number of triangles at planar regions, while ensuring real-time and high quality of visual presentation, and keeping translation, rotation and zooming operations still applicable. When machining precision is evaluated, or overcut, undercut and interference are inspected, full resolution model is automatically restored to ensure the accuracy and correctness of these inspections.
