Abstract
Light field is 4D function descript the flow of light through 3D space. A light field parameterized on the surface offers a natural an intuitive description of the view-dependent appearance of scenes with complex reflectance properties. Light field mapping extract the 4D surface light field data into several terms of view map and surface map to reduce the size. The light field data can be rendered at interactive rates with help of modern graphics hardware. Under the framework of light field mapping, we try to process the view maps extracted from the surface light field data. Since the 2D view maps preserve the light direction part of 4D surface light field parameters, it contains the information about view-dependent property of light field. Actually, the amount of reflected light received by camera depends on the amount of incident light and surface reflectance properties. We try to reflect the view maps around the surface normal to light maps, which can be consider as convolution of light source and surface reflectance properties. Under simple light condition and uniform surface reflectance properties, each light map got from each vertex should be similar. Because of the data have more special coherence, we can compress the data in more efficient way.
