Struct HarmonicMapParameterization 

Source 
pub struct HarmonicMapParameterization;
Expand description

Harmonic map UV parameterization (also known as harmonic embedding).

Maps boundary vertices to a fixed convex boundary (circle) and solves the discrete harmonic (Laplacian) system with cotangent weights for interior vertices. This provides a more accurate conformal-ish mapping than uniform Tutte.

Implementations§

Source§

impl HarmonicMapParameterization

Source

pub fn compute(mesh: &ParamTriMesh) -> Vec<[f64; 2]>

Compute cotangent-weighted UV coordinates for the mesh.

Boundary vertices are fixed on a unit circle. Interior vertices are solved by Gauss-Seidel iteration with cotangent weights.
