Design Appearance Evaluation Tool for Non-prototype Development

Article of Honda R&D Technical Review Vol.25 No.2


The aim with this paper is to achieve a tool for non-prototype automotive development that is faster, simpler, and enables judgment equivalent to that with a physical model. Evaluation by the computer graphics to convey the appeal of shapes by means of artistic effects is commonly used. In non-prototype development, computer graphic output effects allowing the same judgment as with a physical model are required, and this approach has to yield output for evaluation with highly accurate results and by a realistic amount of calculation time without depending on the skills of individuals.
The computer graphic software named Total Objective and Physical Simulation was developed in order to achieve the required computer graphic output with a reasonable amount of calculation time. It was decided that the software would not use manual adjustment of environment and material parameters, but instead handle only data measured from actual objects. In addition, Monte Carlo path tracing specialized for parallel Graphic Processing Units was adopted for the calculation technique. This tool achieved physically correct rendering based on measurement data with a high level of performance.
