      Very weird. It looks like you have a probleme with installation of LibFredo6, which the trace does not show.

      I have to check and come back

        Chris,

        I mean when you are within TopoShaper and have the display of your screenshot, right click and tell me what is the contextual menu.

        Fredo

        Visible on my screenshot :
        right click
        toposhaper ---- > générer terrain (maillage carré)

        best regards

        If you want to say that another particular contextual menu exists
        he/it doesn't function for me
        best regards

          Hi Fredo,

          Thanks again for the awesome plugin (as usual). I was wondering if you (or anybody else) could have a look at this topo to see where I've gone wrong with it. We graded this in the office, and the whole thing is working great except for the rear portion, where there is a bit of a sheer cliff. I wanted to see if you have any thoughts on how I could approach this area on TopoShaper, or whether there's a better way to use it, or if there's something wrong with the terrain itself.

          Thanks!

          Matt

            Matt,

            I had a look. In the area you mention, the issue is that your contours correspond to an overhang. This is not something TopoShaper can handle correctly.

            More generally, I think you can do with less contours, as anyway the shape of the terrain is driven by the grid resolution.

              Hi Fredo,

              First feedback on Toposhaper. Nice tool but I'll have two request in order to make it near to perfection :

              1. Is that possible that Toposhaper can handle guide points with contours simultaneously to generate terrains ? I often have points and contours to define my terrain and that was a big limitation in native sandbox.

              I tried to edit my points (components) where I replaced the point by a little cross but Toposhaper ignores them as they are too small in comparison of other contours.

              1. Next, as we have in Artisan, is that possible to have a crease tool in Toposhaper. I often have a closed contour in border of my terrain and I would like that Toposhaper keeps exactly that contour to define terrain border.

              Hope I'm clear...I'll do more feedback soon.

              Thanks again Fredo.

                This is possible. Point of altitudes could be based on Construction points and small cross components. Simply, the algorithm may not give perfect results if you have too many. Points should be more to mark hill tops, but not as a substitute of iso-contours.

                In the meantime, use circles which have roughly the size of the mesh cells.

                I did the implementation actually just to see, with adjustable creases. The major problem is that the mesh does not follow the contours and therefore you will not obtain the desired result. One evolution I was planning to do is to constrain the mesh to a few contours designated by the user (hence the small editor in the Preview mode). Then it is easy to make them creases and influence the neighboring slope.

                That will be for future releases, not immediately, as I am doing some repackaging of my scripts.

                  I wish just to upload this example made from survey contours (as produced by a civil engineer in California) for reference as you like. It also contains sections I made with "create group from slice" and set to scenes for overlay in Layout (shown in previous post way back on first page).

                      Working with Win 7 and SU 2013, downloaded toposhaper and LibFredo6 4.9c and have problem staring this. I get errors when starting SU 2013:

                        Jesper,

                        You simply did a wrong installation and does not end up with the footprint required, as described in the first post. probably coming from your unzipping operation.

                        I would suggest you install once for all the SCF Plugin Store and then install plugins (TopoShaper and many others) from there, as you don't have to interact yourself with the unzipping operation.

                        Fredo

                                One question. I have a terrain with contours which is 3000x3000m. I have been using TopoShaper for creating terrain, but I have been running problems when changing the grid size from 50x50 to 100x100. TopeShaper always gets stuck in 63% (calculating boundaries). Has anybody else had similar problems?

                                  If you can, could you open the Ruby console when you do the test 100x100 just in case there is a message displayed.
                                  Otherwise, may be the best is to post or PM the model.

                                      The problem is due to an artificial rectangular hull which you includes in the terrain. This prevents to calculate the correct concave hull and therefore the zone of influence of contours.

                                      Fredo

                                      PS: By the way, your model is quite complex, but apparently Toposhaper could deal with it

                                        Toposhaper screen captureHello Fredo
                                        Love your script!
                                        Can't tell you how long I have hoped for something like this.

                                        I am having a problem with a large topo map I am working on.
                                        As illustrated in the attached image, when I go to preview created mesh there are lines that do not correlate with my topo set.
                                        When I generate the mesh, i get this type of deviation.
                                        Can you suggest what might be going wrong?
                                        many thanks in advance.
                                        Best.

                                          Thought it would be helpful if you had topos in case you wanted to run script yourself.

                                            @bobpineo,

                                            Your contour map is extremely large, with close to 30,000 edges, 750 contours, 400 automatic junctions, but also extremely dense, since contours are separated by a very small distance.

                                            It's a miracle that TopoShaper (and Ruby underneath) can do something with it!

                                            There are a number of problems that I detected:

                                            1. do not simplify the contours. There are only 12 simplified, but the contour map is so dense that the simplification creates overlaps with adjacent contours.

                                            2. watch out some automatic junctions at the periphery. Some are overlapping.

                                            3. there seems to be a bug in Toposhaper, because I observe some shadow straight contours in the Preview mode (but not in the Cleanser mode). I keep your model and will have a closer look at it. It may be related to the calculation of the Concave hull.

                                            I run the generation with a 100 x 69 and obtained a result which is not too bad. But with the density of the contours, I think that the sampling should be over 300 x 200 to exploit the high definition of the contours.

                                            I can't tell you what to do exactly to avoid some of the artefacts you may observe, except maybe to remove some contours and try again.

                                            Fredo
