127 3D Object Reflection Rendering Based on Non-Uniform Sampling

Traditional reflection rendering methods have uniform sampling rate over the reflective objects, which cannot provide the surface information sufficiently when data importance and complexity of the surface is non-uniform. Besides, observing the objects, people have one or more visual focus areas. Considering these reasons, rendering reflection requires to highlight corresponding parts. In this paper, a new method for rendering the reflection of 3D objects is proposed, which is based on non-uniform sampling. Our method makes up the shortage of traditional reflection rendering. In the previous phase of rendering, we need to get the sampling map of reflected object image; then according to the sampling map we could gain the distort image of reflected object; finally, render the reflection with the help of reconstruct non-uniform image. Further, we explore the way of generating sampling map automatically. Therefore, it can render 3D object reflection in real time. The work of this paper enables less computation but better effect of rendering reflection in scenarios, using non-uniform image with totally lower resolution.
