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...

I am working on an application where I need to rectify an image taken from a mobile camera platform. The platform measures roll, pitch and yaw angles, and I want to make it look like the image is t...

I'm trying to get a the Euler angle of a Face that is detected by FaceDetector. Here is what I use to output to Logcat: Log.v("debug", " X: " + face.pose(Face.EULER_X) + " Y: " + face.pose(Face.E...

I am using two image of the single object the object is roated certain degree from its first image. I have calculated the POSE of each image and converted the rotational vector to Matrix using Ro...

Quaternions are arguably an appropriate choice for representing object rotations internally. They are simple and efficient to interpolate and represent a single orientation unambiguously. However,...

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 am working through a Python and OpenCV head pose estimation tutorial found here: https://www.learnopencv.com/head-pose-estimation-using-opencv-and-dlib/ I am able to accurately project a 3D poi...

I'm writing a program that loads a file containing a scene description and then displays it using OpenGL. I'm using GLM for all of my math operations. Rotations in the scene file are stored in quat...

I'd like to move an object around another - just as if the one object was a child of the other. This is GDscript - Godot Engine 3.2, but the logic should be very similar to other game engines. Wh...

First of all, I am not a mathematical expert at all. Please be tolerant to my mathematical mistakes and correct me where necessary, I'd love to learn. I have a cube which is rotating using css ani...

I am trying to calculate the rotation of my device when I rotate it around the y-axis in ARKit. For clarification the y-axis in ARKit is the axis pointing upwards perpendicular to the ground. I u...

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 rota...

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().eule...

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 tr...

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-rotati...

Is there an existing algorithm for converting a quaternion representation of a rotation to an Euler angle representation? The rotation order for the Euler representation is known and can be any of ...

I'm working on some simple 3d graphics in OpenGL (java LWGJL), and I'm trying to figure out how to convert yaw, pitch and roll to the x, y and z components of my movement Vector. I know how to do t...

My question may seem trivial, but the more I read about it - the more confused I get... I have started a little project where I want to roughly track the movements of a rotating object. (A basketba...

I know there's a million questions on rotating, I've tried and read many things but I can't seem to solve this particular problem. The only way I can think to explain it properly is with some poor...

I'm using lib glm (http://glm.g-truc.net/) for test quaternion but I've a problem; when I convert euler angle to quaternion then immediatly quaternion to euler angles, my result are totally differe...

I'm trying to get the change in orientation between two deviceorientation events along the left-right axis, and top-bottom axis, those axis being usually defined as the phone x and y axis (https://...

I have a rotating sphere on which I have a div attached the example can be viewed here: https://jsfiddle.net/ao5wdm04/ I calculate the x and y values and place the div using a translate3d transform...

While trying to answer another SO question, the issue of how to calculate Euler angles for dimensions > 3 came up. The RSpincalc package has a straightforward DCM2EA function for converting a 3d ro...

I'm working on motion simulator with 2 DOF (pitch & roll). I'm reading transformation matrix from game and I need to get the angles and send to hardware to drive motors. Since Euler angles have...

I'm sure this is simple, but have not had any success researching this and getting a successful answer. I have rotations defined as three euler angles, in XYZ order, right-handed. I have to conv...
