DeepSDFStruct.deep_sdf.metrics.mesh_to_analytical#

Mesh-to-Analytical SDF Evaluation#

This module provides functions for evaluating mesh quality by computing SDF values at mesh vertices using ground truth analytical SDFs.

This is useful for: - Quantifying reconstruction accuracy - Measuring surface deviation - Validating mesh generation algorithms

Functions

chamfer_distance(mesh_a, mesh_b[, ...])

Symmetric Chamfer distance between two meshes.

mesh_to_analytical(gt_sdf, gen_mesh)

Calculates the SDF for every vertex on the mesh
DeepSDFStruct.deep_sdf.metrics.mesh_to_analytical.chamfer_distance(mesh_a, mesh_b, n_surface_samples=10000)#

Symmetric Chamfer distance between two meshes.

Parameters:

  • mesh_a (trimesh.Trimesh) – First mesh.

  • mesh_b (trimesh.Trimesh) – Second mesh.

  • n_surface_samples (int) – Number of points sampled on each mesh surface.

Returns:

Symmetric Chamfer distance.

Return type:

float
