I am drawing a blank… literally…

Given two XYZ points (say left sphere and right sphere), how can I draw a cube between them?

It seems I would need to get the center point (in XYZ) first…
Then be able to know the size/distance between the two points (I think I can get that thanks to MRdistance)

any and all help is welcome… I promise to share the kinect fun with this if this is possible…

thanks!
tohm
here is starting point I got to (without my disaster trials)

any help on the math? I still can’t find anything…

( xSphere1 + xSphere2 ) / 2. = xCube
( ySphere1 + ySphere2 ) / 2. = yCube
( zSphere1 + zSphere2 ) / 2. = zCube

Good things coming… my plan is to use the Kinect to move “boxes” of samples around a room… I already have the selection and effects built for 3d, now I just need to tweak…

Thanks for your help
