• Defined in File SurfaceFeatures.h

Class Documentation

class SurfaceFeatures

Detect and mark feature edges based on boundary or dihedral angle.

Public Functions

SurfaceFeatures(SurfaceMesh &mesh)

Construct with mesh to be analyzed.

Adds two bool properties to the mesh if they are not already existing:

• "e:feature" to mark feature edges

• "v:feature" to mark feature vertices.

Note

The class never removes the marker properties so that other algorithms can re-use this information. Cleaning up the properties when they are no longer needed is the responsibility of the caller.

void clear()

Clear feature and boundary edges.

Sets all "e:feature" and "v:feature" properties to false.

Note

This does not remove the corresponding property arrays.

size_t detect_boundary()

Mark all boundary edges as features.

Returns:

The number of boudary edges detected.

size_t detect_angle(Scalar angle)

Mark edges with dihedral angle larger than angle as feature.

Returns:

The number of feature edges detected.
