Been trying to reconstruct your building a coordinate frame example, but am a bit stumped as far as how to construct the 3 by 3 rotation matrix from the cross products. What vectors are v1 and v2 supposed to be using? Been reading up on google but am still a bit confused.

i can set in30, in31, and in32 to the x, y, and z position directly from the point on curve node so position is working fine.

]]>v1 = normalizedTangent^normalizedNormal

v2 = normalizedTangent^v2

Right?

I can’t seem to get such a ‘stable’ coordinate frame as in your animated gif.
