Automate mesh triangulation?

Post by litote »

After I have triangulated a vector layer (Draw-Triangulate 2D mesh), if I want to add more triangles I have to manualy draw on more points with the Add Point tool, then retriangulate.

Is there a simple way to add more triangles automatically without having to draw on the points to increase the density of the mesh?

Do you mean you want to subdivide the current mesh? If so, select all the points, select Split, and the re-triangulate that.

If you only want to double the mesh resolution in a portion of the mesh, select only the points in that region, apply Split, then select everything and re-triangulate. Now that portion will have higher resolution but the rest of the mesh should remain similar to what you had before.

@Greenlaw: Thank you! This will save me much time. Great tip about selecting certain points. Blessings be upon your camels.

BTW, with your previous help I was able to create this:

Funny how this guy keeps popping up ... here's my turn: viewtopic.php?f=8&t=27102&p=153205&hili ... in#p153205, and it's already 10 yrs old! As you see, I didn't rely on just one method of animation.

@slowtiger: I'd be interested to see your animation, but the link within the link to the forum you posted does not open for me. Also the dropbox file link is dead. Do you have other working links?

First link works here. Of course the dropbox is dead now!
The other http://slowtiger.de/examples/franklin.mov is a Quicktime movie, you should be able to download and watch it.

I was able to dl it. Thanks. Nice job with reconstructing the eye layer.

One more tip: Before triangulating a layer, I like to duplicate the layer and hide it. This is my backup in case I decide I need to change the polygon flow or some other detail that would be difficult to do with the triangulated version.
