Volumetric is a 3-D image processing tool. It reads pointcloud data, expands it to a volumetric space with highly effective memory usage, and filter out necessary points.
PhotoCloud is a tool to browse and a navigate for datasets composed of (a) a collection of registered images and (b) a 3D model over which images are aligned. The 3D model can be a point-cloud, triangle mesh. PhotoCloud is based on a client/server architecture and it is scalable: very large dataset (both in terms of (a) and (b) can be handled.
