TRELLIS
Official repo for paper "Structured 3D Latents for Scalable and Versatile 3D Generation" (CVPR'25 Spotlight).
Project mention: Image-blaster: Creates 3D environments, SFX, and meshes from a single image | news.ycombinator.com | 2026-05-15Is this in the same vein as TRELLIS?
https://github.com/Microsoft/TRELLIS
I've been trying to use this to generate 3d character models from images. I am enjoying 3d printing these models to mess with my kids.
Not much of what I've found runs on local models but I'm always on the lookout.

Project mention: Beyond Blocks and Lines: How CadQuery is Revolutionizing Parametric Design | dev.to | 2026-04-17
For decades, Computer-Aided Design (CAD) software has relied on graphical user interfaces (GUIs) for creating 3D models. While powerful, these tools often present limitations for automation, version control, and complex parametric design. The typical workflow involves manually creating features, applying constraints, and managing relationships - a process that can be time-consuming, error-prone, and difficult to scale. Many organizations have found that maintaining a history of design changes and adapting models to new requirements can become a significant bottleneck. This is where CadQuery enters the picture, offering a fundamentally different approach.
