The original model.
The non-manifold curves resulting from application of the intersection algorithm. The
non-manifold curves can be resolved by identifying and deleting the interior surfaces.
Most of the feature curves (in blue) are created based on the dihedral angle between
facets. Different feature angles can be used in different parts of the model. Along the
upper surface of the top wing, a feature curve (line) is manually created from the end
After the mesh has been coarsened to get rid of all the extremely small edges created by
the intersection calculation, uniform refinement is applied to the model.
This STL model of a Sopwith Camel consists of 168 disconnected surfaces. The goal here is to produce a high
quality surface mesh with triangles as equilateral as the topology will allow. With DGK, we are able to
resolve the intersections, construct feature curves to preserve important features and remove excessively
small edges. The mesh is then refined to the specified size.
