init(width:height:length:)

Declaration

convenience init(width: CGFloat, height: CGFloat, length: CGFloat)

Parameters

• width:

  The width of the pyramid along the x-axis of its local coordinate space.

• height:

  The height of the pyramid along the y-axis of its local coordinate space.

• length:

  The length of the pyramid along the z-axis of its local coordinate space.

Return Value

A new pyramid geometry.

Discussion

The pyramid’s base is centered in its local coordinate system. For example, if you create a pyramid whose width, height and length are all 10.0, its apex is at the point {0, 10.0, 0}, and its base lies in the plane whose y-coordinate is 0.0, extending from -5.0 to 5.0 along both the x- and z-axes.
