CSG Capsule

CSG Capsule

csg_capsule(start = c(0, 0, 0), end = c(0, 1, 0), radius = 1)

Arguments

start

Default `c(0, 0, 0)`. Start point of the capsule, specifying `x`, `y`, `z`.

end

Default `c(0, 1, 0)`. End point of the capsule, specifying `x`, `y`, `z`.

radius

Default `1`. Capsule radius.

Value

List describing the capsule in the scene.
