```cs public class RectangularConePrimitive : Primitive { // Height of the cone from base to apex public float height; // Length of the rectangular base public float length; // This transform must only contain rotation and translation components, not scale public Matrix4F transform; // Width of the rectangular base public float width; } ``` The base of the cone is centered at `(0, 0, 0)`, and the tip extends upwards to `(0, height, 0)`. > WARNING: the `transform` matrix should only contain rotation and translation operations, not scale. The size of the cone should be controlled via the `width`, `length` and `height` properties
