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.

Line Casting: GameObject Face End Point of Ray

I'm trying to make the enemy object face the end of the line cast. The code I have locks the ray onto the player when detected properly. My problem here is that my enemy sprite is a grandchild of the Rigidbody2D and I'm using eulerAngles to change…

Measure angle for swing motion

I have a pendulum and an IMU sensor that is capable to give me Euler angles and Quaternions. I want to attach the sensor on pendulum and measure θ angle around x axis from the starting position (see the following image). The problem is that the…

What is the tranformation of quaternions written below in code?

I have already ask this on code review, since this is a c++ code, which works, but they said it is better here. So I have some code which rotates a quaternion (orix, oriy, oriz, oriw) to another quaternion, but this rotation is written badly and…

Calculate Euler Angles out of CMRotationsmatrix

I am developing an app, in which I record the device orientation and position of the user. I tried to calculate the Euler Angels (pitch, roll & yaw) out of the Rotationmatrix given by CMAttitude. I was not able to do that. I already read how the…

Rotation around Z axis of world

I am trying to apply a rotation to fix the camera pose in my setup, since one of the axes seems to be off. I suspect this axis to be Z of "world" frame. In other words, I need to rotate "stereo_camera" frame around the Z axis of the "world frame" by…

Is there any way to convert a vector to euler angle?

I have 2 vectors in 3D space, for example: If I know these 4 points, is there any method to find out the euler angles of them? I am trying to move these two vectors to the origin, then assuming these two vectors are rotated from two reference…

Attempting to find pitch and yaw to turn to an object in 3d space

I have two 3d vectors containing position data for two objects within my game. One of the objects needs to turn its camera directly to the other based on the current positions (the setting of the pitch/yaw are absolute so realistically I can ignore…

Can I store child game object's local axis and get it transformed to world axis at runtime?

I have a parent game object A, who has a child B, currently the use of B is just to get its world up axis (child.up) and world position (child.position) at runtime, apart from this they are of no use, so I decided to eliminate them by storing their…
