Struct ProgressiveMeshSimple 

pub struct ProgressiveMeshSimple {
    pub current: SimpleMesh,
    pub history: Vec<EdgeCollapseRecord>,
}

Progressive mesh: stores the base (simplified) mesh and a list of refinement records.

Fields

current: SimpleMesh

Current simplified mesh.

history: Vec<EdgeCollapseRecord>

Collapse history (oldest first).

Implementations

impl ProgressiveMeshSimple

pub fn new(mesh: SimpleMesh) -> Self

Build a progressive mesh from a base mesh.

pub fn collapse_edge(&mut self, src: usize, dst: usize)

Perform one vertex-to-vertex edge collapse (vertex src → vertex dst).

Merges src into dst, removes all triangles that had both src and dst, and replaces src with dst in all remaining triangles.

pub fn n_collapses(&self) -> usize

Number of collapses performed.

pub fn n_triangles(&self) -> usize

Current triangle count.
