Ray casting tsdf

Webconstructed TSDF structure, virtual camera views can be rendered from an arbitrary camera pose – the virtual camera can ray-cast the TSDF structure to identify the estimative surface points. Specifical-ly, the zero-crossing region is identified via a fast search procedure and the estimative surface points are interpolated within the zero- WebModel class maintaining a volumetric grid and the current active frame's pose. Wraps functionalities including integration, ray casting, and surface reconstruction.
