Vector is A (0.500000, 0.707100, 0.500000) and vector B (0.402214, 0.914678, 0.039731); Beg them to two relatively triaxial euler Angle?

Error method: using vector point multiplication and cross-product after get the rotation Angle and the axis of rotation, and then four elements and euler found euler Angle completely wrong (using the euler spiral back validation is wrong),

Hope bosses guidance, thank you!

Note the right-handed coordinate system?

reference 1st floor zhao4zhong1 response:

attention to distinguish the right-handed coordinate system?

- left only the positive and negative rotation Angle difference is rotating in a different order can be accepted, the problem is out of the euler spiral don't go back,

3 d rotation must first solve the problem of which three-dimensional rotated around:
Translation center (x1, y1, z1), X axis rotate alpha, Y axis rotate beta, Z axis rotate gamma, back translation (x1, y1, - z1);
The inverse operation and its corresponding sequence should be:
Translation center (x1, y1, z1), Z axis rotate - gamma, Y axis rotate - beta, the X axis rotate alpha, translation back (x1, y1, - z1)
I think,

Thank you zhao four teacher guidance, two vectors is a unit vector of the origin,

-- miss zhao, whether vertical axis rotate out of matrix singular? Please don't out right euler... dizzy

I am dizzy

Two of three axis is what meaning, you are in for rotating vector (pitch, roll and yaw) from a choice to b?

Euler Angle for, A rotation to B, (both vector origin, and is A unit vector), consult!!!!!

Problem solved?

CodePudding user response:

Are you in the direction of the vector Angle and rotating euler Angle have misunderstanding???????

Euler Angle of rotation, the nature is also a matrix operations, inverse operation is set up, how to verify??

==is not the only solution, there are a few of the multiple solutions is wrong, so it is difficult to get the right solution,

no problem

The code posted and have a look

Hello I want to ask next if it's purely a vector to another vector rotation transformation matrix is there a simple algorithm
