Après installation de la dernière version de Toposhaper (2.3b) et de LibFredo6 v8.1h, Toposhaper ne s'execute pas à l'ouverture de Sketchup, renvoyant un message d'erreur qui est le suivant : "you must install LibFredo6 to run Toposhaper
Open the download page of LibFredo6 at https....".

Après vérification dans l'extension manager, LibFredo est pourtant bien installé. Une idée sur l'origine du bug ?

Il faut verifier que LibFredo6 est bien chargé. Est ce qu'il y a un menu Window > LibFredo6 Settings.... ?

As you can see in the attached image only a part of the terrain is created. If I try with a less dense contour file of the same area it works but I need the detail as high as possible.

Maybe you can make just smaller portions and join them in the end?

Hello,
Great plugin, however I am having an issue, after generating the terrain from guide points, using the toolbar, and clicking off elsewhere, the toolbar disappears and I can't seem to get it back to modify the terrain. How can I get the toolbar back after it has disappeared?

David.

Can you open the Ruby console, as there may be an error.

Did the terrain generate correctly by the way?

I just try TopoShaper with a point cloud with more than 130.000 points out of a ASCII-File. How I can import it in SU and make any kind of terrain model?
Any ideas and suggestions are most welcome!! :fro: :enlight:

I don't think TopoShaper can handle 130,000 points; and I don't think either that Sketchup will not scream with a mesh of 130,000 vertices.
So you'll probably have to find a way, with other tools to simplify the input points or raw mesh, either simplifying, or cutting in pieces if the cloud covers a very large area. I don't know if there are Ruby scripts in Sketchup to do that, but I know there are specialized terrain software that can do it. There are several discussion threads in Sketchucation and Sketchup forums about terrains.

I'm trying to use Toposhaper to create a topo from points. I have points selected and when I run the plugin all I get is a blank error.

Hi,

It would be helpful that you attach your model so that I can investigate. Thanks.

@Rspierenburg

You just need to put all contruction points and the contour within a Group, then select the group and run TopoShaper Cloud.

Note that your model seems to have some points which create peaks.

What can be the reason of such error of TopoShaper?
It appears on SketchUp17 and 18, if I try very simple terrain, just of 2 or 3 curves.

@Anastasia_0111

Could you indicate the text of the error (just just give the files and line numbers), as well as post one of this simple model with free-hand drawn curve.

Many thanks

Hi, Can't get this to work on my Mac. Using the supplied 'test' SKP file I either get a full on program bug splat! a non contoured output, just the shape of the face or the attached useless error message:

Any help appreciated

Hi, Finally got this working on my mac after I realised that it worked on a group rather than selecting points (contrary to some vids I've watched) However, now I've got it working the results I've got are not using all the cloud points in the group. Therefore the result is very "pointy" Any help appreciated

If you include a face (or several) in the group where you have the Guide points, TopoShaper will use them for the contour of the terrain.

Anyway, the best is that you post your model so that I can have a look.

Fredo, first off let me thank you for all of your amazing plugins. I have a request for toposhaper. I don't know anything about coding and/or how difficult this would be. But in surface modeling programs you have the ability to add breaklines which make a more accurate surface. Do you think this can be added?

A Breakline is a line used to connect data representing a distinct surface feature, like a ridge line, edge of pavement, toe of a slope, centreline of a road, or flowline of a ditch or stream. When a breakline is defined, the surface triangulation must first follow the breakline, by placing triangle edges coincident with the breakline segments. This ensures the feature in the model is accurately depicted. Then, the rest of the interpolation is performed based on proximity. Breaklines are typically critical to creating an accurate surface model. It is the interpolation of the data, not just the data itself that determines the shape of the model.

It is complex (it involves constrained Delaunay triangulation), but I finally built an algorithm (I use it already in FredoCorner). I will integrate it in TopoShaper when I can, along with a GUI refresh. This would look like a "from Contour", where you can also influence the terrain with additional guide points.

??
What I wonder how this could be input to the plugin. I'd like to see an example and how it might be implemented on UI level. I suppose edges that are horizontal can be introduced which are defined as firm intersections with the surface and not interpolated with the rest of the terrain. Working-in grades along retaining walls or building walls (rarely level) might be done be definition of point elevations.

My approach is usually working with existing terrain so after TopoShaper I massage it to new work as needed, sometimes cutting the surface where needed, sometimes moving points of the cut portions to fit to new walls or edges of pavement (e.g.). I see that where a vertical face is actually included in the original contours, weird results happen, but I generally rebuild that part or cover it in other geometry (like a model of the retaining wall it represents).

In general, it is better to conceive the terrain before adding decoration, houses, fences, etc...

But I'll think about what can be done, especially for roads.

This would be GREAT addition to this plugin. I do this work manually at present and it is tedious to say the least. This would be a great time saver.

Something interactive like this for roads would be superb.

I think there is already a Plugin, InstantRoad by ValiArchitect.

Anyway, building such a plugin is independent from TopoShaper, as it should apply to any terrain, whatever method has been used to generate it.
