Description
In the code for casting BOX3D to geometry, the six sides of the box are commented as front, back, top, bottom, left and right. However, front and back are the wrong way around. The y-axis points away from the viewer, so the the side with the y-max value is the back.
I trusted these comments, which lead to some discrepancies. It took me several hours to realize the comments, which I took for a fact, were actually wrong.
