Tests:

• test 01: load and save a cloud, get the scalar field names, compute the gravity center
  
  
• test 02: export coordinates to SF, computes its average and standard deviation, and min and max values
  
  
• test 03: compute cloud curvature, filter points by SF value
  
  
• test 04: load a point cloud
  
  
• test 05: access the scalar fields data
  
  
• test 06: manually apply a translation to a cloud, or use the Global Shift mechanism at loading time
  
  
• test 07: load a cloud and a polyine, crope the cloud with the polyline, smooth the polyline, compute its length, etc.
  
  
• test 08: create primitives (box, cone, sphere, cylinder, etc.) or a quadric
  
  
• test 09: create primitives, apply a transformation, and compute the distances between a cloud and these primitives
  
  
• test 10: ICP registration
  
  
• test 11: Delaunay 2.5D triangulation + smooth (see test 14 as well)
  
  
• test 12: apply a rigid transformation to a cloud, fit a plane
  
  
• test 13: compute the cloud octree
  
  
• test 14: export normals to SFs, export some statistics from the resulting SFs
  
  
• test 15: triangulate a point cloud and sample points on it
  
  
• test 16: compute the octree and extract poins inside neighborhoods (spherical, cylindrical or cubical)
