Struct VisibleRegion 

#[non_exhaustive]
pub struct VisibleRegion {
    pub mesh: MeshId,
    pub source: FaceSource,
    pub outer: Vec<Point2>,
    pub holes: Vec<Vec<Point2>>,
    pub triangles: Vec<u32>,
}

A maximal region of the image where one source is frontmost.

Rings are counter-clockwise (outer) and clockwise (holes), start at their lexicographically smallest point and do not repeat it.

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.

mesh: MeshId

The mesh the region belongs to.

source: FaceSource

The group or cap the region belongs to.

outer: Vec<Point2>

Outer boundary.

holes: Vec<Vec<Point2>>

Holes, sorted lexicographically by their points.

triangles: Vec<u32>

Indices of the mesh’s triangles that are frontmost somewhere in an exact region this region was snapped from, ascending. A region that snapping split at a pinch lists the whole set in each part. Empty for FaceSource::Cap.
