code/SDFElongate
Stretches a field by collapsing a box onto the origin.
Sdf3d
Folds a sampled position so that whatever primitive reads it comes out stretched: a sphere becomes a capsule, a box a longer box, and the stretch keeps the original's rounding intact rather than scaling it. Stretching along more than one axis at once is allowed, and gives a shape swept along a rectangle rather than a segment. The twin of geo/SDFElongate, for use inside a geo/SDFBuilder sub-network.
Parameters
| Name | Type | What it does |
|---|---|---|
| P | Vector3 | Position to fold. Left unwired it reads the builder's own sample position. |
| size | Vector3 | How far the shape is stretched on each axis, in total: half of it either side of the center. A negative reads as 0. |
