Abstract:
Recently, many methods have been proposed to realistically render various materials. The realism of the synthetic images can be improved by rendering small-scale details on the surfaces of 3D objects. We focus on the efficient rendering of the scratches on the transparent objects. Although a fast rendering method using precomputed 2D BRDFs for a scratched material has been proposed, the method is limited to the opaque materials such as metals. We extend this method to the transparent objects. On the surface of the transparent object, rays are split into specular reflections and refractions. We therefore precompute Bidirectional Scattering Distribution Functions (BSDFs). We use a 2D ray tracer as in the previous method to accelerate the precomputation. We show several examples to demonstrate the effectiveness of our method.
