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.

Eliminating sign flips in quaternion data from sensors

I obtain sensor data from an AR headset, which outputs the user's head orientation as quaternions. When I inspected the raw data, I saw that there are several significant jumps in the consecutive quaternion samples, especially for qw and qy…

Euler angles -> 3D rotation matrix-> Euler angles with tensorflow-graphics

I'm trying to understand the transformation between euler angles and rotation matrix. Simulating random matrix of euler angles and the transformed them into 3D rotation matrix and back to euler angles do not preserve the original euler…

Free Rotating Camera OpenGL

I'm trying to make a free orbiting camera for a spaceship game. I'm having some trouble with the rotations however. I started by using euler angles, but my implementation kept failing because of gimbal lock, which I want to avoid. I am now trying to…

How to get the y angle between 2 vectors in Three.js?

In Three.js I have 2 3d vectors and I want to find the x-axis and y-axis angle between them. For the x-axis I found this toDegrees(atan2(A.z, A.y) - atan2(B.z, B.y)) from The X angle between two 3D vectors? which works, but for y-axis, I am…

Cube cannot do a full rotation on the Y axis in three.js

I have a low poly world and I added "gravity" with raycasting to my character. Now I need to add another raycaster in front of the character (in this case the pointer lock controls) pointing forwards (always in front of the camera and in facing the…

I can not understand the extrinsic and intrinsic rotation order for `scipy` lib

After some research, for now, I understand scipy has right-handed axis coordinate system, and left-handed rotation. For example from scipy.spatial.transform import Rotation as R np.array([0,1,0]) @ R.from_euler("XYZ", [0,0,30],…

Is there a better way to calculate the direction of a rolling ball in order to make the camera follow it?

Currently I'm using a normalized rb velocity to get the x and z velocity directions in order to compare it with eulerAngles of the camera in order to tell the camera which way to spin. But I'm doing this inside a bunch of nested if statements and…
