Euler angle to Quaternion then Quaternion to euler angle

Share the same interpolation type, changing interpolation for a single channel such as rotateX, will automatically change rotateY and rotateZ as well. For more information on rotation interpolation, see Animated rotation in Maya. Independent Euler Calculates the rotation using three separate angles representing rotations about the X, Y, and Z axes, and an order or rotation. In this mode, the curves that define the rotation for a given node are represented in Euler-angles, interpolation is performed on each curve independently in Euler space, and keyframes may occur at your discretion—they are not synchronized with the other sibling rotation curves at the node. You can also animate a single rotation ordinate. This is the default setting. Synchronized Euler Creates curves that have keyframes on sibling curves locked together but with interpolation between keyframes performed in Euler-space. It’s useful to keep rotation keyframes synchronized because rotation is a composition of the three separate rotate values. Deleting just one key on a curve can have a dramatic and unexpected effect on the interpolation. Quaternion Slerp Interpolation is calculated using spherical linear interpolation and does not depend on the tangents of the input curves. Quaternion Cubic Interpolation is calculated using quaternion cubic interpolation (Squad) and does not depend on the tangents of the input curves. Quaternion Tangent Dependent Interpolation is calculated using quaternion interpolation based on the input curve tangents. For example, if the tangents are linear, Maya uses spherical linear interpolation (Slerp), and if the tangents are clamped, Maya uses cubic interpolation (Squad).

For example imagine that we are aiming a dish at a satellite. The azimuth and elevation are independent of each other, for example we can aim south and then elevate up by the required inclination, or we can set the elevation and then turn and point toward the south. However there is a third angle, we can rotate about

Intro to Quaternions Euler Angles

December 23, 2015, 6:45pm 1 I made a series of camera animations using the Animator component, made transitions from one clip to another + events, all very beautiful in the editor. I hit Build & Run with a Nexus 4 device hooked by USB, using Unity Remote app and I get a blue screen. When I uncheck the Animator component on the Main Camera and build, everything is fine.Ok, there’s some sort of problem with the Animator component on the camera.Let’s use good old Legacy. With previous versions of Unity, you make a cube, add Animation component, make a clip in the Animation window, rotate it - and you have an animation that rotates. This is surprisingly not so in Unity v5.3.1f1.The rotation doesn’t get recorded. Are these bugs or am I missing something. Thanks in advance. Thanks to @ChrisLohSolution:In Unity 5.3, For each Camera or Game object having animation using rotation, right-click on the rotation property that you have key-framed in the animation window, and change the interpolation mode to “Quaternion” or “Euler angles (Quaternion approximations)” instead of default mode “Euler angles”. I’m having the exact same issue in 5.30f ChrisLoh January 27, 2016, 5:25am 3 I get the same problem - camera animation works in the editor but not on Android.The animator on the camera (which contains method triggering events) shows only blue screen during the animation on my Galaxy Note 3. At the start and end of the animation, the camera shows the entire scene - just not during animation.How do we get the Unity team to address this issue?I’m using USB and just Unity’s internal Build & Run. gbabic February 9, 2016, 1:56am 5 The answer from @gohil.krunal.27 / @ChrisLoh worked for me using Quaternion Approximations but not pure Quaternion.Thanks Guys!(Tested on Sony Xperia)

This should make it easier to illustrate the orientation with a simple aeroplane figure, we can rotate this either about the x,y or z axis as shown here: reference orientation φ = 0 θ = 0 ψ =0 rotate by 90 degrees about x axis φ = 90 degrees θ = 0 ψ = 0 rotate by 180

Conversion between quaternions and Euler angles

The line to the satellite, to correctly align with the horizontal and vertically polarised signal from the satellite, this third angle is dependant on the others so we cant escape from this issue.When the angles are small, then they are nearly independent of each other, for example if we are aiming at a small area of sky.Satellite examplesfrotationOn these pages will be developing a class sfrotation (full listing here) which holds a rotation, in addition to coding the rotation as axis angle it can also be coded as euler or quaternion and can convert between these formats.Further ReadingYou may be interested in other means to represent orientation and rotational quantities such as: Axis and Angle Quaternions MatriciesOr you may be interested in how these quantities are used to simulate physical objects: Kinematics This site may have errors.
