Dynamic Visualization Of Three- Dimensional Images From Multiple Texel Images Created From Fused Ladar/Digital Imagery, Cody C. Killpack, Scott Budge

Electrical and Computer Engineering Faculty Publications

The ability to create three-dimensional (3-D) image models, using registered texel images (fused ladar and digital imagery), is an important topic in remote sensing. These models are automatically generated by matching multiple texel images into a single common reference frame. However, rendering a sequence of independently registered texel images often provides challenges. Although accurately registered, the model textures are often incorrectly overlapped and interwoven when using standard rendering techniques. Consequently, corrections must be done after all the primitives have been rendered by determining the best texture for any viewable fragment in the model. This paper describes a technique to visualize …
