| Importance of light source in 3 dimensional virtual space where its division from real world becomes gradually vague contributes outstandingly to the results as much as compared to the importance of light in real world. Since the light tracking technique was announced in 1980, the study on 3 dimensional computer graphics to express property of light in a similar principle to actual phenomenon has realized gorgeous development as much as realizing the diffused reflection phenomenon of light by photon. Such development presents a possibility of realizing all the phenomena recognized by human`s vision in 3 dimensional virtual space. This means that it becomes possible to express a lot of natural phenomena by light in the same principle, and its representative example is realization of caustic effects generated by a complicated phenomenon of reflection, refraction, scattering, diffraction, etc. of light. This study has deduced variables appearing in realizing light phenomenon at virtual space by performing comparison experiments on the basis of general physical phenomenon of light and principle of 3 dimensional computer graphics to express this, and has obtained a result that such variables can be minutely changed by various environments and secondary variables due to interaction between two variables can happen. However, natural phenomenon contains diverse variables that are still unpredictable, so quantitative evaluation of virtual space research for expressing this more exactly should be realized continuously. |
