Yes, but not like in the video.

The morphing I want to do is not just morphing using an x-y-pad.

It's more like morphing from a certain point "A" towards a movable point "X" on a kind of sailcloth that's clamped between 4 or 8 points like this http://www.lisori-sonnensegel.de/tl_files/lisori_referenz/lisori-sonnensegel-referenz_21.JPG in a coordinate system in which every possible point is a certain sound.

The points B,C,D,E span the sailcloth and A is an outside point. Point X is a movable point on the sailcloth like the point of a laserpointer that hits it. It defines the end-position of the distance A-X that is the morphing path.

Every point represents a parameter set that results in a certain sound and all possible positions X can be, are sharing aspects of all edge-points B,C,D,E in a certain ratio to one another.

I want to know, how this curved sailcloth and the point X on it can be calculated and how to move X around.

Is there a mathematical equation that describes that anyhow?

Sorry, I couldn't exaclty say yesterday, what I try to find out...I haven't been sure how to articulate my thoughts so others understand me.
