Hello,

I have another question concerning medical imaging. I have a stack of binary images from which I want to render a isosurface... so far so good. I can extract the isosurface using the marching cube algorithm and render the point cloud; but the object looks very blocky and the edges are sharp. Is there a way to smoothen these data (interpolate between the points)? How can that be realised in OpenGL? I would very appreciate if someone could help me with some good examples

I thank you in advance

chris.

You can use tricubic interpolation like these folks do:
