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

          does it mean we will be able to smooth contour generated surfaces so they will be more natural in shape? good luck with testing

          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 πŸ˜„


              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 πŸ˜‰

                    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.

                                  Coen, would it also be possible to leave the 'knife -like features' on the claw as they where ( I mean not subdivised (and rasor scharp πŸ˜„ ) or is the whole model always subdivised ?

                                      Hi all,

                                      I am looking for one more beta tester at the moment. I need someone with a lot of free time on their hands (anyone??) I am worried that the current testers are too busy to test and post bugs. Is there anyone out there who could commit to spending a LOT of time testing over the next week? First come first serve. Please respond right here.

                                          I can help. I already sent you a private message yesterday about this. I'm currently doing a project which could benefit. Plus, I've experience in scripted solutions.

                                            OK, you got the job! I expect a two page bug report on my desk tomorrow morning. πŸ˜›
                                            Seriously, though, please give as much feedback as you have time for. I will send you a PM later today. Thanks.
