Struct EdgeSelection 

#[non_exhaustive]
pub struct EdgeSelection {
    pub crease_cosine: Option<f64>,
    pub boundary: bool,
    pub silhouette: bool,
    pub group_boundary: bool,
    pub hidden: bool,
}

Which edges to draw.

An edge with one incident triangle is a boundary edge. An edge with two is a silhouette when the two triangles’ image orientations differ (a triangle seen edge-on is its own orientation, so the test is symmetric and independent of winding), and otherwise a crease when the cosine of the angle between their normals is strictly below crease_cosine, and otherwise, when group_boundary is set, a group boundary when the two triangles are in different FaceGroups (ADR 0106). The kinds are exclusive in that order: a silhouette is never a crease or a group boundary, and an edge that is a crease at crease_cosine is never a group boundary. With group_boundary unset the face groups are ignored.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

crease_cosine: Option<f64>

Crease threshold in [-1, 1]; None draws no creases.

boundary: bool

Draw boundary edges.

silhouette: bool

Draw silhouette edges.

group_boundary: bool

Draw edges between triangles of different face groups that are neither silhouettes nor selected creases. The groups are resolved as for MeshVisibleFaces (FaceGroups), and a PerTriangle slice of the wrong length is refused.

hidden: bool

Also report the hidden pieces.
