Explanation of creating a rounded shape. Maybe helpful for few here

On a slightly related note. As part of another project I wrote a module that creates cubes with arbitrary edge radius, you can even specify 12 different radii, one for each edge of a cube. Generating a smooth cube corner where three different radii meet is not trivial, so I went through several iterations (as can be seen from the code). Code is generally optimized for speed Just linking to it here in case someone finds it interesting. It's a work-in-progress that has stalled at the current stage so it could benefit from some cleanup and general improvements. https://github.com/kharar/AirSense/blob/main/OpenSCAD_files/corner.scad On Sat, Mar 30, 2024, 02:54 Sanjeev Prabhakar via Discuss < discuss@lists.openscad.org> wrote: > Explanation of creating a rounded shape.

Hi Martin, this sounds very interesting to me. right now I am creating a "fillet" module in my branch, where I intend to select certain edges by providing "selection cubes" and round them. Corners are actually not trivial, this is why I looked into your scad code. i cant open it from here see https://imgur.com/a/s885Bic corners have different numbers of rounded edges. right now the selected edges are hardcoded in the program, but i will work on this next.

Sorry for the confusion. I just realized the repository I linked to earlier contains sensitive information so instead of making it public I just moved the OpenSCAD files to its own public repo. This should help: https://github.com/kharar/RoundedPrimitives/blob/main/corner.scad On Sat, 30 Mar 2024 at 22:12, Guenther Sohler <guenther.sohler@gmail.com> wrote: > > Hi Martin, > > this sounds very interesting to me. > right now I am creating a "fillet" module in my branch, where I intend to > select certain edges by providing "selection cubes" and round them. > Corners are actually not trivial, this is why I looked into your scad > code. i cant open it from here > > see > https://imgur.com/a/s885Bic > > corners have different numbers of rounded edges. > right now the selected edges are hardcoded in the program, but i will work > on this next. > > > > > > On Sat, Mar 30, 2024 at 9:58 PM Martin Axelsen via Discuss < > discuss@lists.openscad.org> wrote: > >> On a slightly related note. >> As part of another project I wrote a module that creates cubes with >> arbitrary edge radius, you can even specify 12 different radii, one for >> each edge of a cube. >> Generating a smooth cube corner where three different radii meet is not >> trivial, so I went through several iterations (as can be seen from the >> code). >> Code is generally optimized for speed >> Just linking to it here in case someone finds it interesting. >> It's a work-in-progress that has stalled at the current stage so it could >> benefit from some cleanup and general improvements. >> >> https://github.com/kharar/AirSense/blob/main/OpenSCAD_files/corner.scad >> >> >> >> >> >> On Sat, Mar 30, 2024, 02:54 Sanjeev Prabhakar via Discuss < >> discuss@lists.openscad.org> wrote: >> >>> Explanation of creating a rounded shape.
