#Stretching an object
7 messages in this thread
What is the best way to stretch an object so that the texture map stretches
with it? I can see the idea of creating a morph of the beginning and end
position, but what is the best way to achieve the end position of the object? I
want the end position to to be in the shape of an hourglass. Thanks.

When you move vertices the mapping coordnates move with them so it's kind of a
no brainer. Now bear in mind that the orignal mapping coordinates are going to
stretch on a vertex to vertex basis – unless all the vertices are being
scaled/rotated uniformallly the mapping for the _entire_ mesh is not going to
be uniform.

Well, actually, I was trying to get a suggestion on how to give the object a
"stretched" look, like an hourglass shape.

Gotcha ya. The best way to make an elegent hourglass is actually to loft it. If
you have an exsiting mesh and want to"pinch" it in to an hour glass then you
need to perform a series of 2D Scales to rows of its center vertices (select
the whole middle vertex group and scale 90%, deselect the top and bottom rows
and scale another 90%, deselect……and so on..)

I was afraid of that 🙂 Thanks for the suggestions.

Don't be afraid, James. Unless you've got a very unusual object, this is a no
brainer. Just use Select/Vertex/Quad, draw the "box" around the center of your
object, press the "X" key (to have operations performed around the object
center rather than world coordinates) and do a 3D scale from the top view. It
will take all of about five seconds (you can even copy the object first and end
up with a morph target).
James,

When you stretch an object with the mapping coords allready applied, the coords
will stretch to.
