Re: [Visualpython-users] text color problem?

Thanks much for the report. In vis/primitives.py, the code for
changing color and material for a text object should look like this:

    def set_material(self, material):
        self.extrusion.material = material
    def get_material(self):
        return self.__material

    def set_color(self, color):
        self.extrusion.color = color
    def get_color(self):
        return self.__color

These corrections will of course be in the next update to VPython. I
also found a mistake in text.starts, but that's less used.

History: The year-old 3D text object had a component to convert text
to contours, and Python code to generate faces objects to render the
3D text. With the new extrusion object also needing to be able to
convert text to contours, that subroutine was split out as
shapes.text() and the text and extrusion objects both call
shapes.text(). In the process of doing this restructuring I failed to
change the setters for text.color and text.material. Note that the
text object creates an extrusion object, but this doesn't make the
text object obsolete, because it places emphasis on such things as
upper left and lower right locations, etc.
