[Plugin][$] TopoShaper - v2.7a - 01 Apr 24

I think I said this before. Excellent work on this!

When I use it I wish the grid could be set to a standard horizontal square dimension and set to always align to the origin. then work can be more easily patched and combined.

Another wish is for the edges to be restricted to conform (close as possible) to land on a bounding contour. Again this will help joining with other forms.

does toposhaper can use this sort of file ?
Because it generates bugs!
(I have last version Prog / Lib )

Pilou,

What do you mean by 'use'.

Did you generate the terrain via Toposhaper QaudMesh instead?

Start from this file

No just speedy by hand for the grid (a copy/Move square) + SandBox for deformation

The plugin requires Point cloud or isocontours.

Seems that is the key !
When I create points from the file then use TopoShaper that works!
(except for the little triangle bottom left corner? )

PS The alert message when you select points who are not a group/ component is empty!

fredo6

Pilou,

Could you post the file with the point cloud. I'll check for the missing triangle and the missing message.

Which Sketchup version do you use by the way?

Fredo

pilou

It was from the file previous linked!
But here with the points!
I have the 2015 and all at the last versions (plug and Lib) !

test_topo_points.skp

pilou

Resolved!
We must press Concave contour first!

When I run the toposhaper using terrain generator, although the contour lines setting is set to 1.0' increments, the first contour line above O.O' becomes 0.783' instead of 1.0'. After that, the contour line intervals are all 1.0' apart.

What could be the cause of this? How can I fix this?

Thanks. Ben

topo.skpHere is the file of cloud points

Hi my friends,

i have a little problem.. i tried to model a cloud point to get a soil.. everything ok, except some peek and deep that the plugin generate, and i don't know to get rid.

You see in the attached screen, and in the skp file with point.

Hope in your help! Thanks man!!

no one could help me?

What would you expect from such a point?

If you only have some of these, you can move the vertices afterwards manually.

Or you can use a plugin to smooth the surface after the creation.

If you only have a limited number of these points above the terrain causing the spikes then delete these points before running Toposhaper.

Why not use Triangulate Points first by TIG ?

derei

After playing with TopoShaper I ended up with several (three) terrains overlapped. Why this happened? It seems I am missing something in functionality of this plugin, so instead of refining the just created terrain, I end up with new modified copies of the terrain.

I have some deeps and some peeks. I don't know why this happened.
I know that i can move up and down these points to get a level.. but i would like to understand how to evitate those problem.

Why suggest to use triangulate point instead of toposhaper? toposhaper is much better than triangulate point for this, or not?

Thanks mate!

pilou

It was just a suggestion for have a preview of the terrain and maybe see if there are not aeras where some confusion between near vertices are possible!
And give to Toposhaper faces and not only vertices!

Pilou,

The first iteration of TopoShaper is precisely the Delaunay Triangulation (same results normally as with the Falé /TIG plugin).

@orei: the spikes are due to singular points with very different altitudes compared with immediate neighbours. TopoShaper CloudPoints generates a surface passing through the points.

My suggestion would be that:

you generate the group of isocontours from the triangular mesh (an option in TopoShaper Cloud)
then from the isocontours group, you generate a quad mesh terrain, using the other tool of TopoShaper.

This will smooth the spikes
