truck — Rust CAD Kernel#

Pure Rust B-Rep CAD kernel with WebGPU rendering.

What It Is#

truck is a Rust library for B-Rep (Boundary Representation) solid modeling. It provides:

truck-modeling: Geometric primitives, sweeps, boolean operations
truck-platform: Scene management, camera, lighting, event loop
truck-rendimpl: PBR rendering, instance creation, wireframes
truck-meshalgo: Mesh algorithms and tessellation
truck-shapeops: Boolean operations (union, subtract, intersect)

How We Use It#

truck is cloned to .src/truck/ as a path dependency. Our crates/truck-webgpu-gui/ crate builds on top of it to create the CAD application.

Key Operations#

Operation	truck API
Create cube	`builder::cube(vertex, edge)`
Create sphere	`builder::sphere(center, radius, ...)`
Create cylinder	`builder::cylinder(bottom, top, radius)`
Translate	Modify vertex positions in topology
Boolean union	`truck_shapeops::and(solid_a, solid_b)`
Boolean subtract	`truck_shapeops::or(solid_a, solid_b)` (inverted)
Extrude profile	`builder::tsweep(face, vector)`
Revolve profile	`builder::rsweep(face, origin, axis, angle)`

Serialization#

Solids serialize to JSON via serde. This preserves full B-Rep precision (no tessellation loss).
