avila-tesselation

IFC Geometry Tesselation - 100% Rust

Converts IFC parametric solids to triangle meshes.

Features

• ExtrudedAreaSolid: Profile extrusion with caps and sides
• BRep: Boundary representation with face triangulation
• Primitives: Box, Cylinder, Sphere tesselation
• Configurable: Adjustable tolerance and segment counts

Example

use avila_tesselation::{Tesselator, IfcGeometry, Profile, ProfileType};
use avila_vec3d::Vec3;

// Create tesselator
let tesselator = Tesselator::new(0.01); // 1cm tolerance

// Define rectangular profile
let profile = Profile {
    profile_type: ProfileType::Rectangle { width: 2.0, height: 1.0 },
    position: Vec3::ZERO,
};

// Extrude to 3D solid
let geometry = IfcGeometry::ExtrudedAreaSolid {
    profile,
    extrusion_direction: Vec3::Z,
    extrusion_depth: 3.0,
};

// Tesselate to mesh
let mesh = tesselator.tesselate(&geometry)?;
println!("Triangles: {}", mesh.indices.len() / 3);
