Our standard of selection hardware for CAM/CAM operations: GPU Check the limitation of software. Ex.「OpenGL 3」「2GB GPU Memory」「DirectX 11.2」 Refer to detail information of recommendation well. Detail information is usually opened to public in the website of Software vendor. Rough estimate on GPU Memory(Estimation of Verticies). Count number of maximum vertex. Ex. In 100mm x 100mm area Create line with 0.01mm pitch. Set sampling pitch to 0.01mm. The number of vertex is 100 million. Using fp32, simply amount of memory is 1.1GB. Performance FP32 and FP64. Some GPU has a gap between power of FP32 and power of FP64. Generally geometrical calculation for CAM uses FP64 on not GPU but CPU. Also Minute!.
