Auditable counts for one hidden-line operation.

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.

source: HiddenLineSource

Approximation source.

source_meshes: usize

Input meshes.

source_triangles: usize

Input triangles, summed over all meshes.

selected_edges: usize

Edges of the selected kinds, before clipping.

point_edges: usize

Selected edges whose image is a single point. Such an edge is counted here only, before clipping: it is neither drawn nor counted in clipped_edges, whatever the depth range or the region.

clipped_edges: usize

Selected edges removed entirely by depth clipping or the region.

candidate_pairs: usize

(edge, triangle) pairs examined for occlusion.

exact_escalations: usize

Decisions the fast filter could not settle and the exact tier did. This count may differ between two otherwise identical requests (for example with the triangles reversed); it is not part of the drawing.

collapsed_segments: usize

Pieces dropped because their rounded endpoints coincide.

visible_segments: usize

Visible output segments.

hidden_segments: usize

Hidden output segments.

Implementations

impl HiddenLineEvidence

pub const fn input_mesh( source_meshes: usize, source_triangles: usize, ) -> HiddenLineEvidence

Evidence for a drawing derived from the input meshes; the remaining counts start at zero for the provider to fill in.

pub const fn is_derived_from_input_mesh(self) -> bool

Whether this result came from the discrete input meshes.
