1. Yoshinori Tanimura is a researcher working on truck, a Rust CAD kernel, for 3 years. 2. Truck is a Rust CAD kernel that reimplements B-rep geometry with NURBS. 3. Truck is designed as a collection of small crates, taking inspiration from Theseus' ship, with crates for tasks like 3D modeling, visualization, and WebGPU utilities, building upon the work of senior projects like OCCT, VTK, and three.js.

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

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!
