Least Squares Conformal Maps parameterization.

Implementations§

Source§

impl LscmParameterization

Source

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

Compute UV coordinates for the mesh using a simplified LSCM approach.

Pins the first two boundary vertices and solves iteratively.

Source

pub fn conformal_energy( positions: &[[f64; 3]], uvs: &[[f64; 2]], triangles: &[[usize; 3]], ) -> f64

Compute conformal energy: sum of |J - R|^2 per triangle.

J is the Jacobian of the UV mapping, R is the closest rotation.
