Point Cloud is a set of points describing a 3D space. The point cloud is a derived content type of the 3D reality mesh generated by regular sampling of space and surfaces at a target resolution.

Product Constraints

3D reconstruction is determined by the ability to reliably resolve objects from at least two different viewing angles.

  • Objects hidden or occluded would not be reconstructed reliably.
  • Typical sensible point spacing would be around 15 cm (i.e. consistent with our 3D resolution), however larger or smaller spacing can be supported.
  • The point cloud will not contain any extra information than the textured mesh; if we cannot resolve in the mesh, the point cloud will also be the same.
  • Point cloud will likely be significantly larger in file size than the 3D mesh. Specialized software can optimize the storage of point cloud to make it perform better
  • The  point  cloud is unclassified in the sense that points are not labelled as ground, tree, building, etc. as is often done for Lidar point clouds. 


  • No labels
