Struct ProgressiveMesh 

Source 
pub struct ProgressiveMesh {
    pub mesh: SimpleMesh,
    pub history: Vec<CollapseRecord>,
}
Expand description

Progressive mesh: stores the sequence of collapses so the mesh can be coarsened incrementally and the collapses can be reversed.

Fields§

§mesh: SimpleMesh

Current mesh state.

§history: Vec<CollapseRecord>

Collapse history (oldest first).

Implementations§

Source§

impl ProgressiveMesh

Source

pub fn new(mesh: SimpleMesh) -> Self

Wrap an existing mesh.

Source

pub fn collapse_one(&mut self) -> bool

Perform one QEM-based edge collapse (cheapest edge) and record it.

Returns false when the mesh has ≤ 3 triangles and cannot be reduced further.

Source

pub fn decimate_to(&mut self, target_triangles: usize)

Reduce the mesh until it has at most target_triangles triangles.
