Hi,
I'd like to adjust the behaviour of the picker. Currently when I click on a
complex surface the picker chooses the closest vertex along the ray-traced(?)
line intersecting the view at the current mouse position - regardless of depth
in the image. The images I'm exploring are the folded cortical surface of a
brain hemisphere and the picker frequently selects vertices at the "back" of a
fold or even the back of the hemisphere rather than the one nearest the viewer.
Is there a way of making it to choose the one nearest-to-the-viewer? Perhaps
there's a way of getting the list of all the vertices which are within
tolerance so I can use my own code to determine which of those to select?

The modern datacenter depends on network connectivity to access resources

connectivity to a physical network are well understood - see how these
rules translate into the virtual world?
