# Rebend

Rebend was designed to help alter the curve of an already curved object, in an easily animatable way.

First you match the Rebend Deformer to your object's existing bend, then define the new bend you'd like to achieve, and finally you can animate the strength to blend between the two bends.

The curve of this 'S' is being modified by Rebend. The setup in this image is also using Rebend's deformer to avoid modifying the bottom left section of the S, and Attach Falloff to Null to control the position of that deformer.

## Options

1. Original angle - the angle of the existing bend.
2. Original length - the length of the existing bend; match both of these first two settings to the existing curvature of the object you'd like to deform.
3. New angle - the angle of the bend you'd like to deform your obejct to.
4. New length - the length of the bend you'd like to deform your object to.
5. Strength - use this to blend your object between the original and new bend settings (negative values are allowed and will bend your object away from the 'New angle' and 'New length' settings).
6. Twist - changing this setting alters the new heading of your rebent geometry.
   The next group of settings control how Rebend applies the new curvature to your object, and a little background into how Rebend works should help understand these. The original angle and length settings define a portion of a circle that Rebend should gather points from, then the new angle and length settings define a portion of a different circle to deform those points to. The limit settings refer to points around the original circle.
7. Unlimited - by default Rebend changes the curvature of the original circle portion, and points beyond that arc are moved and rotated as a group to match the movement of its end point. When 'Unlimited' is turned on Rebend instead changes the curvature of the full circle.
8. Automatic limit - automatically decides which points around Rebend's original circle to leave alone and which points to move by setting the cutoff point in between the 'Original angle' and 360°.
9. Limit - when 'Automatic limit' is turned off you get explicit control over where that cutoff is using this setting.
