Thanks for pointing me to that.
11 years goes fast...

I've been exporting Blender data through .x3D which does a nice job of
formatting, but the rotations are written as quaternion. I tried tweaking a
quaternion to euler script in VB but failed. Below is a .x3d transform block.

<Transform DEF="pointData_032_TRANSFORM"
   translation="9.958521 56.574299 -0.017123"
   scale="0.154254 0.154254 0.154254"
   rotation="0.000000 0.707107 0.707107 3.141593"
