So I have written a Quaternion based 3D Camera oriented toward new programmers so it is ultra easy for them to integrate and begin using. While I was developing it, at first I would take user input as Euler angles, then generate a Quaternion based off of the input for that frame. I would then take the Camera's Quaternion and multiply it...
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, presenting quaternions in the user interface is generally inappropriate - Euler angles are generally much more familiar to users, and their v...
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 the six permutations (i.e. xyz, xzy, yxz, yzx, zxy, zyx). I've seen algorithms for a fixed rotation order (usually the NASA heading, bank, rol...
I need to calculate the 2 angles (yaw and pitch) for a 3D object to face an arbitrary 3D point. These rotations are known as "Euler" rotations simply because after the first rotation, (lets say Z, based on the picture below) the Y axis also rotates with the object. This is the code I'm using but its not working fully. When on the groun...
I'm trying to use WPF integrated 3D classes to rotate a WPF 3D model. I'm stuck. I'm looking for the 10 or so C# instructions which in pure 3D WPF would rotate a model based on Euler's angles as input (yaw, pitch, roll): RotateTransform3D myTransform = TheSolution (yaw, pitch, roll) I'd then use myTransform to rotation myModel (myMod...
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 z rotations are positive using the left hand rule (thumb pointing to +infinity) My tria...
I have two euler angles. e1 = Angle in parent coordinate system (means angle applied to child coordinate system). e2 = Angle in child coordinate system. The two coordinate system may not have same origin, means that child coordinate system could be translated in 3d space. Now how could i combine these two angles so that resulting angle...
how to convert Quaternion orientation output of wintracker II device to Euler Angles output only. Because Wintracker II device Output Euler angles and Quaternion orientation. i want to Euler angles output only. ...
I need a way to get euler angles for rotation in global frame of reference from a local. I am using c#, wpf 3d and a gyroscope. I have a globe on the screen that should move in the same way as the gyro. Since the gyro sends movement relative to itself I need to use quaternions to keep the state of the object and update it but I'm stuck. ...
I have two Cartesian coordinates. There are xyz and BIG XYZ. I want to make these are parallel to each other. For example, x paralel to X ,y parallel to Y and z paralel to Z. I use a rotation matrix but I have a lot of different rotation matrices. For example I have 3D point in xyz Cartesian coordinates and it's called A and I want ...
How to convert from Euler's coordinates E1 = (x1, y1, z1, yaw1, pitch1, roll1) to E2 = (x2, y2, z2, yaw2, pitch2, roll2) where x, y, z are the coordinates of a point and yaw, pitch, roll the direction/orientation of a vector which origin is the point. yaw is around y, pitch around x, roll around z. They are performed in that ord...
I hope this is the proper location to ask this question which is the same as this one, but expressed as pure math instead of graphically (at least I hope I translated the problem to math correctly). Considering: two vectors that are orthogonal: Up (ux, uy, uz) and Look (lx, ly, lz) a plane P which is perpendicular to Look (hence inclu...
I'm using Catia software. When I query the position of an object inside my CAD drawing, the system returns a 3x4 matrix [Rotations | Translations] I think that the Rotations are expressed in a ZXZ fashion but for further processing I'd like to convert that rotation matrix to a XYZ notation, is this something doable? Edit: My object ...
I have to write a compass app in Android. The only thing the user sees on the screen is a cube with a red wall which has to point north. This is not important. What's important is that I need to rotate that cube accordingly to the rotation of the device itself so that the red wall continues to point north no matter how the phone is being...
Inspired by this question that attempts to reverse engineer a pseudo code chunk, I'm wondering how to use the Rodrigues' rotation formula to calcuate an Euler angleset for one point to face another (between 2 points). I've seen some implementations of the formula, such as this C++ implementation which calculates a rotation matrix. Is th...
