scanning works both axis now, far more accurate image slice.
Refactoring the image slicing.  Using lines for sampling where entry/exit of volume. Introduced JQuery ui for hiding images when not being viewed.
Image slicing complete, stack of images gathered, next MC
Setting up to evaluate mesh per voxel passing the relevant image slices.
Send correct vertical slice to the custom MC algorithm
EOD : trying to see is point lies on line segement, so far, not so good
Is point on line segment "appears" to be working now, unit tests pass at least.  Calling it here while is still have the urge to live.
Added functionality to make collection of lines unique so as to reduce calculation time on certain operations.
working towards the vertex interpolation
MC render of volume sample now works.  Added a second inner sphere just make it a bit more interesting.  It also works but it is not spring jointed or connected to outer sphere. Not sure if worth hassle as want to wrap this up.
