Description

In recent years, landscape simulation with reflection on a transparent object is important for pre-evaluation of city planning or new buildings. Reflection rendering on a flat glass is comparatively easy, however, that on a curved glass is difficult. In addition, there are some cases where multiple images are reflected for one object. Therefore, in this paper, we propose a rendering method of reflection on a curved transparent object by calculating the positions of mirror reversed images from the eye position, CG model and the curvature of the curved transparent object, and by generating mirror-reverse models based on the solutions. Finally, we could simulate the reflection on a curved glass not only for just one reflected image but also for multiple images.
