CSG Cone

csg_cone(start = c(0, 0, 0), end = c(0, 1, 0), radius = 0.5)

Arguments

start

Default `c(0, 0, 0)`. Start point of the cone, specifing `x`, `y`, `z`.

end

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

radius

Default `1`. Radius of the bottom of the cone.

Value

List describing the box in the scene.
