Questions tagged [euler-angles]

The Euler angles are three angles introduced by Leonhard Euler to describe the 3D orientation of a rigid body.

The idea of Euler angles is to split the complete rotation of a cartesian coordinate system into three simpler rotations about the axes of this system. Euler angles also represent three composed rotations that move a reference frame to a given referred frame. This is equivalent to saying that any orientation can be achieved by composing three elemental rotations (rotations around a single axis), and also equivalent to saying that any rotation matrix can be decomposed as a product of three elemental rotation matrices.

Roll pitch and yaw from Rotation matrix with Eigen Library

I need to extract the roll pitch yaw angles from a rotation matrix and I want to be sure that what I do is correct. Eigen::Matrix< simFloat, 3, 1> rpy = orientation.toRotationMatrix().eulerAngles(0,1,2); const double r = ((double)rpy(0)); …

Euler to Quaternion / Quaternion to Euler using Eigen

I'm trying to implement a functionality that can convert an Euler angle into an Quaternion and back "YXZ"-convention using Eigen. Later this should be used to let the user give you Euler angles and rotate around as Quaternion and convert Back for…

Conversion euler to matrix and matrix to euler

I'm trying to convert a 3D rotation described in term of euler angles into a matrix and then back, using .NET/C#. My conventions are: left handed system (x right, y top, z forward) order of rotations: heading around y, pitch around x, bank around…

Euler angles between two 3d vectors

How do you find the 3 euler angles between 2 3D vectors? When I have one Vector and I want to get its rotation, this link can be usually used: Calculate rotations to look at a 3D point? But how do I do it when calculating them according to one…

Correcting the Yaw part of one Quaternion by the Yaw part of another one

I have the following problem: A quaternion (q1) from a motion capturing device needs to be corrected by the yaw angle (and only yaw!) from another orientation quaternion (q2) derived by a second tracked object, so that the pitch and roll of q1 is…

Three.js setFromRotationMatrix strange behavior when rotation is over 90 degrees

I have objects which each have a separate parent for each rotation axis (1 for X-rotation, 1 for Y-rotation, and 1 for Z-rotation. They are all related to each other in that order as well: X-rotation object is a child of the Y-rotation object.…
