MATLAB: How to apply variable transparency to a plot using scatter3

3dalphamarkersscattertransparency

I'm producing a 3D model, and interior points happen to be more interesting to me. I have a 4-column matrix representing (x,y,z,intensity), and I'm most interested in the high-intensity points; currently they're coloured by intensity. Can I make it so that the transparency of low-intensity points is increased (but I need them to still be visible)?
Thanks

MATLAB doesn't allow you to control the transparency of markers.
If you don't have a tremendous number of data points you could try drawing small spherical surfaces at each data point. Then you could control the transparency of those surfaces. Here's a File Exchange submission that might help you get started.
