Real-Time Surface Material Editing of 3D Objects

When artists design models,they usually need a tool for real-time material editing. Based on recent based on precomputed radiance transfer techniques,this paper proposes a novel method for real-time editing object material under complex environment lighting. First,we precompute the visibility for each vertex as a precomputation stage; Next,at rendering stage,we on-the-fly compute bidirectional reflectance distribution function (BRDF). Finally,we render the object material by looking up visibility of each vertex. Using the proposed method,the users could edit the material by simply adjusting parameters of BRDF. Our method achieved real-time dynamic editing under dynamic viewpoints and changing environment lighting.
