Any insight on this problem?  or am I basically creating the
patches and plot incorrectly?

The summery now:
From a 3D volumetric array:
patch(reducepatch(isosurface(x,y,z,A, 0), P))

I want to plot some of the surface coordinates for
illustration, using "plot3"

However, many datum points (esp in concave area) got hidden
"inside" the model, even when the point size is huge, as
shown below:

Gianni suggested setting alpha to 0.1 to show the points,
but the model is then too transparent, displaying not only
the surface points, but everything.  Problem with export
also, where transparency is not supported in vector-based
format.

PS: is this a proper newsgroup, and is top-post/bottom-post
preferred?  can't find it in the rules, and I'm reading this
from the mathworks website also....

Thanks
