title: 8 meassurements (cube) in 3D space - interpolate between the values by one 3D position
body: <p>I measured data in a 3d space. lets say temperature in a room for example. the 8 measurement points are arranged like the edges of a cube. I have room coordinates and temperature data for each point.</p>
  
  <p>Now I track a moving person within the same space. Based on the person's actual position I want to interpolate between the 8 values to assume the temperature at that point in space.</p>
