DEVICE FOR DISPLAYING CUTTING SIMULATION, METHOD FOR DISPLAYING CUTTING SIMULATION, AND PROGRAM FOR DISPLAYING CUTTING SIMULATION

摘要

In order to reduce the amount of computation required for ray tracing and facilitate simulating of changes in workpiece shape even on an inexpensive, low-performance computer, a device for displaying a cutting simulation includes: a rendered workpiece image update section for updating by ray tracing a portion of a rendered workpiece image buffer and a rendered workpiece depth buffer, the portion being associated with a rendering region corresponding to a change in the shape of the workpiece; a rendered tool image creation section for rendering a tool image by ray tracing for the current tool rendering region; and an image transfer section for transferring a partial image of the previous tool rendering region and the current workpiece rendering region to be updated from the rendered workpiece image buffer to a display frame buffer as well as transferring the current tool rendering image to the display frame buffer.
