Math Help: jit.gl.gridshape between two points XYZ


    Feb 03 2011 | 5:29 am
    Hi all,
    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)

      This should help a bit -- got rid of the mesh (you don't need it) and sent loadbang to the positions of the two spheres.

      thanks, it was a quick and dirty mock up....
      any help on the math? I still can't find anything...

      Add the respective position values of the spheres together and divide by 2?
      ( xSphere1 + xSphere2 ) / 2. = xCube ( ySphere1 + ySphere2 ) / 2. = yCube ( zSphere1 + zSphere2 ) / 2. = zCube

      I just had the same idea... and it works! 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
