<plane> explanation of equation could be clearer
Last modified: 2009-04-09 23:45:28 PDT
Add to <plane> element's <equation> child element, after the equation Ax+By+Cz+D=0, this text (per old note from Stan M.):
where ABC is the normal and D is the distance from the plane to the origin. Positive values of D put the plane below the origin.
