      Subdivide and Smooth version 1.0 Final Features List

      • Low-poly proxy subdivision modeling
      • Automatic updating of subdivision surfaces while editing a proxy (optional)
      • Material inheritance of proxy model to subdivision surface (optional)
      • Creasing tool - allows toggling of fully creased edges or vertices
      • Up to 4 subdivision and smooth iterations
      • Unlimited proxy subdivision models can exist in the same file
      • Subdivision and smoothing of a single isolated face
      • Robust subdivision algorithm that can handle almost any geometry
      • Subdivision without smoothing (linear subdivision) - also triangulates all meshes and maintains material assignment
      • Mesh smoothing (vertex averaging) without subdivision - maintains material assignment
      • Extrude tool - useful for modeling clean geometry that subdivides well
      • Knife subdivide tool (aka 'Zorro')

      Testing begins this week! (sorry, invitation only). I will keep you all posted on the release date!

          I am not sure what all the features exactly mean, but it does sound really cool ๐Ÿ˜‰.

            whaat you rock! I can't wait for this release! you are one of those for whome the human cloning was meant in the first place ๐Ÿ˜„ its interesting that you mention mesh smoothing (without subdivision), does it mean we will be able to smooth contour generated surfaces so they will be more natural in shape? good luck with testing

                By the look and feel of it I think the name should be 'Organix' as it does give one the abllity to model organically.

                  Can someone post a complicated contour generated surface? I would like to test this. Thanks.

                      Thanks remus,

                      Here are the results:

                      First image is the original surface generated from contours
                      Second image is the same surface after performing vertex averaging (same number of polys)
                      Third image is the surface after performing two subdivision and smooth iterations

                      It seems like vertex averaging will be very useful to generate more realistic landscape surfaces without increasing poly-count. The only problem is that the the resulting surface will no longer coincide with the contours, so real-world accuracy is lost. There is no easy way to change this so don't ask ๐Ÿ˜„


                      original surface


                      Mesh smoothing (vertex averaging without subdivision)


                      after two subdivision and smooth iterations

                        Just tell them it's an erosion feature thrown in for no charge.

                            brilliant whaat - exactly as expected - the surface is much more natural, as for the accuracy - I guess the the vertex-averaged surface could meet the controur lines by simply moving it along the Z axis a bit, and even if they can't touch everywhere - the result is better for its smoothness, you can't take the contours for benchmarking since their accuracy is fairly limited too ๐Ÿ˜‰

                            maybe performing a test could prove my point>

                            1. create a curved surface with the Smoove tool

                            2. generate contours either by the dedicated script, or by intersecting with equidistant planes

                            3. group contour lines and create a surface by using the sandbox tools

                            4. paint this surface a different color from the original

                            5. make a copy (change the color) of this new surface and apply your script

                            6. compare original surface with both new surfaces

                            whaat thanks for making sketchup better, can't wait for you to release.

                                Yummy !
                                Terrific results as far as I see.

                                This together with a 'wrap texture around object' feature could possibly make other 3d party organic model software trash can material.

                                Good stuff Whaat!

                                      It would be great if you could do a script that could make high poly models low poly. It would be awsome.
