Only display useful cameras to texture a mesh

[eprana]

The user want to select a mesh and only see the cameras that can be used to texture this mesh.

Solution 1:

• retrieve the bounding box of the selected meshes

• retrieve the 3D points of the point cloud visible in this bounding box

• retrieve the cameras from the visibility of those points

• hide other cameras

  ++ only useful cameras -- need the visibility information to work

Solution 2:

• Retrieve all the vertices of the selected meshes

• test the intersection of thoses points with all cameras

• hide other cameras

  -- will get to much cameras -- more computation is required than in the solution 1 ++ don't need the visibility information to work
