tilt, base_slope and azimuth are <rotate> elements recognized by collada.

Benefits:

  • they are understood by a non-pv 3d software
  • PV software can easily read the last number and based on the sid indentify that tilt is 21.8, azimuth is 45 and base_slope is 10

Notes:

  • the order is important
  • the axis (first three numbers in the element), is constant
