[Plugin] Randomize Sandbox TIN (Sep 12, 2011)

Jim

Adds some random height (Z Axis) to an existing Sandbox-created TIN (Group).

To use, select a Group (don't "open" the Group) then select "Randomize TIN" item in the Plugins menu. It should work on any triangulated mesh.

A dialog prompts for the Height (h). Mesh vertices are randomized between the range -h to h along the Z axis.

The original Group is not modified, but a new Group is added in the same location as the original Group.

Keeps perimeter edges.

Works in Model units.
Added option to Keep/Randomize the perimeter.

Thx for the heads-up Jim. This will make creating a water surface (amongst other things) much easier and more natural looking.

I downloaded this plugin, but I can't get it to function. Also, the tutorial on the site isn't working, is it hosted anywhere else?

What exactly doesn´t work? Do you have Sandbox tools enabled?

You need to select the terrain group and then run the plugin.

Thank you,
this will come very handy for water surfaces.

This is a great plugin. Is there something like randomize tin that will work on surfaces that have been subdivide or subdivided and smooth. I have a sculpture of a dolphin and would like it to look more rough like it has been carved out of rock. Any such ruby?

Nice One Jim. But I got a request if you don't mind... Would it be possible to keep the perimeter "untouched" in order to be able to randomize a TIN without modifying its limits ?!

Thanks.

I can try.

Perhaps if you exclude all vertices from the randomization set if they have fewer than 6 edges [that are in the selection to allow for 'island randomization'] OR perhaps if they have any edges that are not 'smooth?'...

Jim

Updated to exclude outer edges when randomizing.

Thanks!

Thanks Jim - I have also had this on the wish list!

Retains original edges.

Should it not read as "retains original perimeteredges"? If "all" edges are retained, there is no randomization.

You're welcome.

Yup. Fixed. Thanks.

Here's something I'm playing with: Drop TIN.

TIG

Looks similar to my DropVertices - what will it do exactly ?

Satisfy my curiosity for a short time.

Jim,
Sorry to bother you, but is it possible to let you choose if you want to keep the perimeter or let it be randomized (as it was in the first version).
As I stated it is a wonderful tool to create water (for instance in swimming pools)but of course, in that case, the perimeter needs to be randomized as well.
greetings, erikB

Jim

Updated with an option to Keep or Randomize the perimeter.

Thnx Jim. It is a really useful plugin.
