Detailed Description

template<typename PT, typename PD, typename INDX>
class bsptreeD2disp03< PT, PD, INDX >

Display a bsp tree's partitions with lines, direction and initial point p0.

The color indicates the direction. Blue is at the bottom of the line and red at the top for the half-space pointing to the left.
