Ideal for complex geometry
Where the geometry of the object of interest is complex, 3D meshes prove to be effective. Features such as berms or scour beneath a vertical structure are tricky to visualise completely using point clouds only.
3D meshes are preferable to grids for areas of complex geometry. Grids are 2.5D surfaces allowing only one depth value per cell, which as such are unsuitable for representing complex 3D objects.
Through generating a 3D mesh from a dense point cloud - such as those created by our mechanical scanning sonar - complex geometry is accurately represented.
