3D image producers:
	SBEM, kind of (rectangular prism voxels
	Confocal
	MRI (and variations, plus CT, these are really 3D)
	Ultrasound, kinda
	Some others

A lot of what I do is working with 3D images!
	No real surprise here
	Extracted structure video, in lab_pres folder

3D presentation:  Concepts, working with 3D on the GPU

GPU is not required for 3D image processing
	GNA didn't use one
	CASTER doesn't use one
	ImageJ barely does

Really, it just means you have one more dimension
	Most 2D math can be extended to 3D
	Each voxel has 6 or 26 neighbors, instead of 4 or 8
