✦ Synopsis
diffuse environment) because of its capabilities of modelling transparency, reflectance and refractions. But the amount of time it takes to generate one single picture is so long that it is not interactive, thus it is as unacceptable to the realtime design interface as its counterpart, polygon rendering. Maybe the next generation of hardware architecture in display device will support ray tracing. But it is questionable that those quality requirements (e.g. transparency, reflectance and refraction) are that urgent, (besides, many of the mechanical parts that are to be modelled are metallic).
Third, ray tracing has its impacts on geometric modelling, e.g. shadow generation, mass calculation and hiddenline removal. It also has severe limitations with respect to traditional drafting aids, data extraction, user interface, dimensioning and tolerancing, etc.
Fourth, the author chose ray tracing for visualization perhaps simply because it is difficult to obtain close
