| Abstract |
| The radiosity method is one of the methods used in global illumination simulation, and it is a rendering technique that requires a lot of CPU time. The form factor calculation is the most time consuming part of its flow. Since hemisphere was introduced in the radiosity algorithm, it has been the most basic form factor calculation model. In this paper, we use a geodesic dome to approximate the hemisphere, and represent the dome with a set of points. When the form factor is calculated, a kD Tree can be also applied to select the projected region. This method is simpler and faster than the conventional hemicube approach, because it avoids processing such as polygon clipping. |
