Hello everyone !
i have a question related to morphing with Ansa.
Let's say i have a geometry i want to morph with a deformation map.
The deformation i want to apply is pretty simple, i have 4 vectors : X, R, DX, DR. X for abscissa, R for Radius. It is a 2 dimensional deformation.
But my geometry is a 3D Model.
Would it be possible to tell Ansa to morph the geometry in an axisymmetrical manner ?
meaning :
X becomes X + DX
Y becomes Y + DR * cos(theta)
Z becomes Z + DR * sin(theta)

My main concern is :
If i build a table X, Y, Z, DX, DY, DZ, I have to sample theta. And if i do that, i will end up with a sort of "petal" deformation (along theta sampling). Because Ansa will interpolate in a linear manner between theta samples.
Thanks a lot for your advices !
