SDF · Cylinder
Finite cylinder SDF with axis along Z:
d_xy = length(p.xy) - radius
d_z = |p.z| - height/2
d = min(max(d_xy, d_z), 0) + length(max(d_xy, 0), max(d_z, 0))Capped at top and bottom — rays that miss the side wall will still hit the caps.

Sockets
center (in)- Vector3. Origin override.
radius (in)- Float.
height (in)- Float.
sdf (out)- SDF.
Parameters
Center- Cylinder origin (midpoint between caps). Default: [0, 0, 0].
Radius- Side-wall radius. Default: 5.
Height- Full height — cylinder spans z ∈ [-height/2, +height/2] around center. Default: 10.
