3. What is truck?

Truck is a Rust CAD Kernel.

4. Demo

5. Three concepts of truck
● Trendy Tools: Rust + WebGPU
● Traditional Arts: NURBS, B-rep
● Theseus' ship: a collection of small crates

6. Trendy Tools: Rust and WebGPU (wgpu)
● Targeting the next generation of market share
● Maximize the performance of each crate by optimization

7. Traditional Arts: NURBS, BRep
Re-implementing the B-rep with NURBS

10. Great seniors of truck
● Open CASCADE Technology (OCCT)
• open source CAD Kernel
• C++
• the core of FreeCAD
● Visualization Tool Kit (VTK)
• Mesh visualization and filters (smoothing, and so on...)
• C++
• the core of ParaView

11. Great seniors of truck
● three.js
• Makes it easy to use WebGL
• Javascript
• WebGL 1.0, little WebGL 2.0
Each package should not aim to be upwardly compatible with its
predecessors. The functions that are covered by each of them should
be defined in a single crate.

12. Future Works as CAD Kernel
● STEP I/O (joint work with @termoshtt)
● Boolean operation for solids
● Incorporated into RICOS Production Suite

13. Goal as WebGPU utility
Primitive Unity whose asset store is crates.io!
