Abstract
In this paper we present a novel and efficient depthimage warping technique based on a piece-wise linear approximation of the depth-image as a textured and simplified triangle mesh. We describe the application of a hierarchical triangulation method to generate triangulated depthmeshes efficiently from depth-images, discuss alternative depth-mesh segmentation methods to avoid occlusion artifacts, and propose a new technique to reduce exposure artifacts that exploits hardware accelerated warping and weighted blending of multiple depth-images in real-time. Applications of our technique include image-based object representations, large scale walk-through visualization systems, as well as terrain rendering.
