Net of triangular pyramids
show user profile  Vladko
I would like to achieve this effect -

I have an box and I want to put it into a net of triangulat pyramids. I tried with 3ds max tessalation, but no luck.. How could I do it?

Thank you.

Curtain Wall Wizard should get you close....triangulate your mesh first tho'.

Easily done with Populate:Panels script as well.

Use this ^^^

I keep posting the link to that dated wizard out of habit.

I really thank you for the fast replies..
The problem is that I can't make my object in triangles. My object now is with curves.. so my aim is to make curves with triangles ( something like the geodesic sphere ).
These plugns are nice.. but after I make the net of the object..

If its a spline cage right click on it and convert it to nurbs spline. Do some uv lofting and convert it to editable poly. It all be triangles then.

Or u can tesselate modify a poly version.

Kirk out.

A wireframe of your mesh might be helpful to get the right advice.

On the right side is my object - mesh ( imported from autocad )
On the left the object is with 'tessellation' modifier. And this is the effect I would like to achieve.. The problem is that I want this triangular net to be more clear - one type triangles..

I don't see why you couldn't use a paneling plugin for this, like the ones mentioned above. I don't know what you mean by you want the triangles to be more clear. You mean uniform? Now that you've triangulated the mesh, try experimenting with procedural modeling to get the desired effect. In edit poly, select all faces, inset slightly, then delete. This should leave you with a lattice cage of triangles. Add a shell modifier, and you should end up with a triangle facade. If that doesn't work, use Populate Panels to panel your object with triangular tiles.

You can also check out Para3D to parametrically tile the object with triangles, just like grasshopper for rhino.

Also, If you are interested in getting the same kind of triangle topology you see in that example image you showed us above, apply a Subdivide modifier to the top of your quad mesh. Then, increase the size parameter large enough that it splits every quad in half diagonally (basically exposing the triangulation of the quad with center edge), then use edit poly to select faces, inset, delete, shell, etc., to achieve the triangulated lattice skin.

Another option is to turn the edge direction using the Topology tools in Graphite, then select lines of verts and connect / cut them to give you the triangular mesh.

The problem with this is you need to have an even quad mesh beneath, you can get there by connecting edges, inserting loops, or the quickest way would be to snap planes to the walls of your building then adjust the segments to get even squares then turn the edges & connect, or turn on vertex snap and use the cut tool across the lines of verts.
Fiddly to do but probably gives you more control.

EDIT: I think you could get by without the parametric approach, just a few insets and extrudes are needed to get the panel form right.

I agree with FX that this is quite simple to achieve in various ways through modifiers, Graphite Tools, and plane ol polygon techniques. However, unless you keep the modifier stack intact (use edit poly modifier to make face insets, etc), you won't be able to make adjustments very easily should the client request them, so I'd recommend keeping a logical stack when doing this kind of thing if you don't wanna go with parametric panel solutions.

^^^ agreed I was assuming he was a noob and no client was involved.

Is there anyway to tame the subdivide modifier ? I understand it's purpose for radiosity, but things get funky on non uniform meshes.
