Module volume_mesh 

Volume mesh structure for tetrahedral and hexahedral meshes.

Overview

VolumeMesh supports both tetrahedral (4 vertices) and hexahedral (8 vertices) cells. Mixed meshes are supported by using 8-index cells where unused indices are set to u32::MAX.

Interior/Exterior Faces

Only exterior faces (not shared between cells) are rendered. This is determined by hashing sorted face vertex indices and counting occurrences.

Quantities

Supported quantities:

• VolumeMeshVertexScalarQuantity - scalar per vertex
• VolumeMeshCellScalarQuantity - scalar per cell
• VolumeMeshVertexColorQuantity - RGB color per vertex
• VolumeMeshCellColorQuantity - RGB color per cell
• VolumeMeshVertexVectorQuantity - vector per vertex
• VolumeMeshCellVectorQuantity - vector per cell

Example

use glam::Vec3;
use polyscope_structures::VolumeMesh;

// Create a single tetrahedron
let vertices = vec![
    Vec3::new(0.0, 0.0, 0.0),
    Vec3::new(1.0, 0.0, 0.0),
    Vec3::new(0.5, 1.0, 0.0),
    Vec3::new(0.5, 0.5, 1.0),
];
let tets = vec![[0, 1, 2, 3]];
let mut mesh = VolumeMesh::new_tet_mesh("my_tet", vertices, tets);

// Add a scalar quantity
mesh.add_vertex_scalar_quantity("temperature", vec![0.0, 0.5, 1.0, 0.25]);
