CSG Pyramid

Note: This primitive slows down immensely for large values of base and height. Try using csg_scale() with this object for large pyramids instead.

csg_pyramid(x = 0, y = 0, z = 0, height = 1, base = 1)

Arguments

x

Default `0`. x-coordinate on the pyramid.

y

Default `0`. y-coordinate on the pyramid.

z

Default `0`. z-coordinate on the pyramid.

height

Default `1`. Pyramid height.

base

Default `1`. Pyramid base width.

Value

List describing the box in the scene.
