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.

Three.js Quaternion Rotation Not Applying Properly

I'm building an app that includes a rotation tool. I almost have it working but not quite. To give a visual, here's a screenshot: In the image, the red dot is the center point, the green dot forms the first line of the angle, and the blue dot…

OpenGL third person camera using quaternions

I'm trying to implement a third person camera in OpenGL. I'm able to get it to work without any problem using euler angles and basic trigonometry: float cameraDistance = 10.0f; float cameraPositionX = sin(targetRotation.y) * cameraDistance; float…

OpenCV：How to use the Euler angle to determine camera orientation

I got a question about how to use the EulerAngle to determine camera's orientation First, I used solvePnP function and got two output "rvec" and "tvec", then I use Rodrigues to convert rvec to rotation matrix "R". After that, I calculated EulerAngle…

Problems rotating objects using eulers - quaternions

I'm having problems rotating GameObjects in my engine. I'm trying to rotate in 2 ways. I'm using MathGeoLib to calculate maths in the engine. First way: Rotates correctly around axis but if I want to rotate back, if I don't do it following the…

How to adjust euler angle by quaternion

I am looking for a way of returning an euler angle that has been rotated by a quaternion. I understand that extracting pitch roll and yaw from a quaternion is problematic at best, but if I could then I would simply add its values to my own in order…
