Reshading Light Fields

Reshading Light Fields

SKIGRAPH, Canada - Mars 1999
We propose here a series of techniques which allows reshading light fields. We assume that there is no depth information available with the light field, and our steps consists of the following: (1) determining a coarse geometric shape of the object by creating an octree of cells occupied by the object, (2) estimating surface normals from the boundary points so determined, (3) estimating the reflectance properties by making simplifying assumptions about the surface re- flectance function. Once these steps are done, one can insert the object within standard geometric models, determine visibility and shade the whole scene (including shadows and intereflection if necessary) to produce images where light fields and geometric objects are integrated. We have only began the implementation work, and this paper is a research plan rather than a report of results. In it we give the motivation and backgroundfor our application, and describe the techniques we plan to use, and give the reasons we selected them.
