Description Ellen Finch 2009-04-09 23:44:49 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.
