{{description>Interpolate between two Shapes with Variable Mix Shapes for use as input to Shape Extrusion, allowing varied interpolation along the extrusion.}}
====== Variable Mix Shapes ======
<note>This component is used in example scene(s) such as:

27_CGVariableExtrusion.</note>
Blends two [[..:datatypes#Shape|Shapes]] into one, with a blend ratio that changes along the extrusion. Connect its output as the Shape input of a [[.:shapeextrusion|Shape Extrusion]] module.

<note tip>Example use: a tube that starts as a circle and gradually becomes a square.</note>
For a fixed blend that stays constant along the extrusion, use [[.:mix|Mix Shapes]] instead.



===== Slots =====

==== Inputs ====
^ Name ^ Type ^ Description ^
| Shape A | [[..:datatypes#Shape|Shape]] | First shape |
| Shape B | [[..:datatypes#Shape|Shape]] | Second shape |

==== Outputs ====
^ Name ^ Type ^ Description ^
| Shape | [[..:datatypes#Shape|Shape]] | The blended shape, varying along the extrusion |

===== Settings =====

=== Mix Curve ===
A curve defining how much of each shape to use at each point along the extrusion.
  * **X axis** - position along the extrusion (0 = start, 1 = end)
  * **Y axis** - blend value (-1 = all Shape A, 1 = all Shape B)
