BUG: ConvexPolyhedron world bounding box result can be undefined.

var minx,miny,minz,maxx,maxy,maxz;

If the vertices are processed in coordinate order, either the min or the max value for that coordinate will never be set because the else clause "if ... minx === undefined" etc. will never be hit.

This can happen randomly, force instance, with a tetrahedron lying on the ground due to rounding errors in the vertical coordinate.
