      Thanks. I was kind of wondering whether multiple convex shapes could be combined. The algorithm generates too much convex shapes for complex models. It would be nice to have a cleanup method which then combines final convex groups if they together are still a convex shape.

      Anton,

      This would be another type of decomposition (say a "blockify" method). Convexify does the job, and none of the small pièces can be combined to form a bigger convex piece. In the camel, many of the mesh quads have a diagonal that is a concave edge.

      For collision, I guess that what you need is an approximate block decomposition that would be visually sufficient to give the impression of contact.

        So next plug will be to tranform it in a real solid! 😉

        Did you try Solid Inspector by thomthom. I think TIG also has a plugin for that.

            I am having a problem with Convexify. I am running SU15 Make. I have this tool on another computer and it runs seamlessly. I can't figure out why it won't work on this computer.

            Running the tool seems to work at first where I get prompted to use the whole model (if nothing is selected) and then I can select the convex decomposition parameters. Once I click "OK" the green hour glass comes up, but then nothing happens. The second I move my mouse, the hour glass changes to a pointer as if nothing ever happened. Any clue to what's going on here?

              Unfortunately, I have exactly the same problem.

                  thank you a lot
                  is it possible to keep the exploded model?

                    Will be fine if we can exit with an actual position of the animation Explode Convexify colored view!
                    (with colors or not)
                    Or does exist a trick ?
                    (sure I can use other thing like Explode-view, Animator, ... but that give not the colors etc...

                        It's seems to be relative with angular tolerance.

                            Even more evident for 2 simple circles extruded! 😮
                            Dashed lines should be the good ones!

                              Pilou,

                              This is normal.

                              The corresponding vertices of the inner and outer circles are not 'aligned', that is, the line joining two corresponding vertices does not go through the common center of the circles.

                              This is a frequent issue when drawing co-centric circles. Because they are made of segments, it may important to keep them 'aligned'. I must say that the Circle tool does not help too much for that.

                              If Convexify was 'following' your edges in the current model, the pieces would not be convex or would have to be divided in smaller chunks.

                              Fredo

                                That is some ennoyous! 😄
                                So we must found a trick!
                                Because make drawings with concentric Circles or Arc-circle are very commune! 🤓

                                  Ok I found one 😄

                                  Drawing concentric circles on the same alignment! 😄

                                  here the red axe!

                                  GIF_same_align.gif

                                  PS Now if you can exit during the animation for keept the position of objects & colors
                                  that will be cool! 😄
