I think I've spotted a minor bug in OSGVolumeDraw.cpp: one edge (between
points 2 and 6) is drawn twice, while another edge (between points 3 and
7) is omitted. I'm pasting the relevant code below:
glBegin(GL_LINE_LOOP);
glVertex3fv(pnts[0].getValues());
glVertex3fv(pnts[1].getValues());
glVertex3fv(pnts[3].getValues());
glVertex3fv(pnts[2].getValues());
glVertex3fv(pnts[6].getValues());
glVertex3fv(pnts[7].getValues());
glVertex3fv(pnts[5].getValues());
glVertex3fv(pnts[4].getValues());
glEnd();
glBegin(GL_LINES);
glVertex3fv(pnts[0].getValues());
glVertex3fv(pnts[2].getValues());
glVertex3fv(pnts[1].getValues());
glVertex3fv(pnts[5].getValues());
/*glVertex3fv(pnts[2].getValues());*/ glVertex3fv(pnts[3].getValues());
/*glVertex3fv(pnts[6].getValues());*/ glVertex3fv(pnts[7].getValues());
glVertex3fv(pnts[4].getValues());
glVertex3fv(pnts[6].getValues());
glEnd();
