在本文中，我们提出了一种用于点采样几何的光能传递方法来计算光的漫反射。大多数传统的光能传递方法将物体的表面细分为小元素，例如四边形。然而，点采样几何不包含有关表面的明确信息，这给将传统方法应用于点采样几何带来了困难。所提出的方法通过计算间反射而不重建任何表面来解决这个问题。该方法实现了光照模拟，同时又不失点采样几何的优点。
In this paper, we propose a radiosity method for the point-sampled geometry to compute diffuse inter reflection of light. Most traditional radiosity methods subdivide the surfaces of objects into small elements such as quadrilaterals. However, the point-sampled geometry includes no explicit information about surfaces, presenting a difficulty in applying the traditional approach to the point-sampled geometry. The proposed method addresses this problem by computing the inter reflection without reconstructing any surfaces. The method realizes lighting simulations without losing the advantages of the point-sampled geometry.
