Smart Mesh and handles

Post by Reindeer »

When I triangle a mesh and animate it I can move and animate the points but I can't seem to animate the point handles. The handles appear alright and they work on the mesh but don't have any effect on the image using that mesh. I'm probably doing it wrong, but no alt-drag ctrl-drag will do the trick.

The bezier handles of the triangulated mesh do not have an effect on the image. This is because image warping is based on point position, not curve angles. Once you triangulate a shape, changing the curves in the mesh have no real meaning because it doesn't change the position of a point or its relationship to other points in the mesh.

Hope this explanation helps.

Thank you. I was misled by the presence of curve handles, because it seems to indicate you actually can use them.

Yeah, TBH, it threw me off at first too. It was only after really thinking about why I couldn't change them that I realized changing them wouldn't matter anyways. :wink:

Maybe the handles become useful again if you kill the polygons and wish to create a new shape from the points? Maybe not...just thinking out loud. But I usually just make a backup layer of the curves before I triangulate the mesh and edit that if I need to...it's much easier that way.

I don't think I understood that :D What do you mean by killing the polygons and back-upping the curves?

Sorry, I guess that was a little vague.

I meant if you want to edit the structure of the original shape (like if you need to add more points to the shape or change the shape entirely) to revise a mesh, it might be easier to work from a copy of the original curves made before the original triangulation, instead of trying to get the triangulated mesh back into a 'bezier editable' form.

I always duplicate the curves before triangulation, and delete the duplicate only after I'm sure I got the mesh exactly right.

Thank you for the clarification :)
