3D visualization GUI

Loads triangulated .obj meshes and displays them using OpenGl and Qt also performs a segmetation algorithm on depth maps taken form a kinect sensor and loads databases of 3D models and extracts dFPFH descriptors which then uses for search and retrieval given a partial 3D model.

Operations it performs:

1. Voxel grid filtering
2. Statistical outlier filtering
3. 3D model search and retrieval
4. 3D image segmentation
