Sand stone rock

This 3D data of Sand stone rock was made using photogrammetry. This is my first attempt in using photogrammetry process. i have photographed over 82 images from all directions and the data was processed using Agisoft Photo-scan. later used Mesh-lab to generate mesh from point cloud, zbrush to reconstruct poly’s in quads and Maya for Unwrapping. Guys feel free to drop some comments or feedback on this work. it will be helpful for me in improving next time :)
