[vtkusers] STLWriter producing pixelated images?

[Hp07]

Hi all,

I am using CT image scans rendered into a 3d graphic. When the image is
displayed in OpenGL the 3d image is smooth and clear - im happy with the
image. When i however try to read the saved .stl file in wxpython, the image
is more pixelated compared to the orignally displayed image in vtk. 
Is there paramters that i may need to inlcude to reproduce a similar image
to the orginal?

any advice will be much appreciated.

Many thanks in advance.

The code i used to open a .STL files using 3d rendered images from vtk is
found on:
