Prickly Pear Cactus Patch with Cactus Wren Nest

3D Model

This structure is a mature patch of prickly pair cactus that is home to one nesting pair of coastal cactus wren. Carolyn Somvilay photographed this cactus patch at the Biodiversity Reserve adjacent ot the San Diego Zoo Safari Park. Our goal is to estimate cactus habitat volume and surface area using measured markers.

This is our first attempt at cactus habitat modeling - and we would like to resolve the following issues: How to fill in gaps created by shadows and inaccessible photo angles?
