Unnamed

Added to vismach.py:

# capture current transformation matrix
class Capture:
    def __init__(self):
	self.transform = []

    def capture(self):
	self.transform = glGetDoublev(GL_MODELVIEW_MATRIX)

And inside class O:

    def redraw(self, *args):
        if self.winfo_width() == 1: return
	self.model.traverse()
	print tooltip.transform    <---- added


Added to scaragui.py:

global tooltip
tooltip = Capture()
tool = Collection([
	tooltip,
	Sphere(0.0, 0.0, tool_len, tool_dia),
	CylinderZ(tool_len, tool_radius, tool_dia, tool_radius),
	CylinderZ(tool_dia, tool_radius, 0.0, 0.0)])

result:
