GPU-based solid modeller for complex objects
Themes: Software technology & Intelligent Systems
A TRL is a measure to indicate the matureness of a developing technology. When an innovative idea is discovered it is often not directly suitable for application. Usually such novel idea is subjected to further experimentation, testing and prototyping before it can be implemented. The image below shows how to read TRL’s to categorise the innovative ideas.
Robust geometric computation is essential to deal with the complex geometry in the design phase, and print path generation in, 3D printing. This new modeller is faster, simpler, and more robust as current alternatives.
Instead of explicitly defining and computing geometry, this Layered Depth-Normal Image (LDNI) based method represents objects as a collection of images. With LDNI, operations like scaffolding and offsetting can be executed near real-time compared to hours.
A number of test cases has demonstrated the robustness and effectiveness of the developed modeller. The open source solid modeller is ready to be further integrated into various computer-aided design and manufacturing software systems.
