Stretches or squashes a Solid or a field by separate factors along X, Y and Z about the origin. A Solid stays a Solid and a field stays a field. With Re-distance on, the values are multiplied by the smallest factor so a Solid stays close to true distance; off, the values are left as they are.
The Solid or field to stretch.
Stretch factor along X; 1 leaves it unchanged, negative mirrors.
Stretch factor along Y; 1 leaves it unchanged, negative mirrors.
Stretch factor along Z; 1 leaves it unchanged, negative mirrors.
On: the values are multiplied by the smallest factor, so a Solid stays close to true distance. Off: the values are left as they are, so a stretched distance field no longer measures true distance.
Values the block gives besides its output. The editor lists them under Properties, and an input can read one by reference.
