CSG Plane

Note: This shape isn't closed, so there may be odd lighting issues if it's oriented the wrong way.

csg_plane(x = 0, y = 0, z = 0, normal = c(0, 1, 0), width_x = 4, width_z = 4)

Arguments

x

Default `0`. An x-coordinate on the plane.

y

Default `0`. A y-coordinate on the plane.

z

Default `0`. A z-coordinate on the plane.

normal

Default `c(0,1,0)`. Surface normal of the plane.

width_x

Default `10`.

width_z

Default `10`.

Value

List describing the plane in the scene.
