Detailed Description
Basic 3D primitive.
An object that actually draws something. Derived objects generally create a display list upon construction that is drawn by this superclass.
- Note
- Objects will generally by aligned along the Z axis and centered on the origin.

Default constructor.
The default color is white.
Member Function Documentation
◆ align()
Align primitive along axis.
Align a centered z-axis aligned primitive along end-start, starting at start.
- Returns
- length of vector.
◆ quad()

Draws a four-sided polygon using two triangles.
Assuming the polygon is in counter-clockwise order, the triangles are as well.
