Yeah, I think that's a consequence of how they're constructing the objects. But things like signed distance fields make that easier* because it'd just be "expand the SDF by 3mm" - https://github.com/fogleman/sdf https://github.com/fogleman/sdf has `shell` for this.
* if you can wrap your head around the math/geometry, I guess
- dTal 5y agoExcept that only works when the distance field accurately represents Euclidian distance, which it certainly won't the minute you apply any sort of non-trivial distortion.
- zimpenfish 5y agoDo you have examples?
- dTal 5y agoSure. Non-uniform scaling, bends, and twists all render the distance field non-Euclidian.
