rotation

问题 I don't know why it don't work. I am using jQuery 2.1.0 I have this code: $("a.shownav img").rotate(180); How can I make it work without using a plugin? 回答1: for using .rotate() , you need to add jqueryrotate plugin. This can be also achieved using pure jQuery and CSS. Try this: $("a.shownav img").css({ "-webkit-transform": "rotate(180deg)", "-moz-transform": "rotate(180deg)", "transform": "rotate(180deg)" /* For modern browsers(CSS3) */ }); 回答2: Use .css() in jquery $("a.shownav img").css(

问题 I am trying to find a way so that the player can drag and rotate an object freely using the mouse (click to view scene). As you can see the script to move the object works just fine, the problems come when you want to rotate it. In fact it works the firts time that you try to rotate the object. If you release the mouse and try again, the object snaps back to its initial rotation before being rotated by the mouse again. I don't want that. I want it to continue the rotation from where it is.

问题 In Unreal, I want to rotate an actor where the forward vector points at target's current position, to ensure that the up vector of my actor is the same at the up vector of my target In Unity3D, it's super simple. It's a single line of code (source): transform.LookAt(target, Vector3.up); In blueprint, there's a Node called "Find Look at Rotation". The problem is that there's no Up vector parameter, so when you are close to the target, you can have a unwanted roll rotation. So, how can I create

问题 My images are always like this: But I need to rotate them to be like this: But to do that, I need to find the orientation of the object, knowing that the thinner part of the object has to be on the left side. In summary, the images are wings and the start of the wing has to be on the left side and the end of the wing has to be on the right side. I hope someone can give me a suggestion, I've tried a bunch of different strategies but with no good result so far. 回答1: Here is one way in Python

问题 Excuse the length of this question, but I have a swift UI that has words displayed in concentric circles. I want to be able to press the right and left button and have the words rotate clockwise and counterclockwise respectively. My withAnimation{} button function works as long as the text is not in a ForEach loop. Is there a way to change state variables that are in a ForEach loop? In my case animate a rotation of a view that is within a ForEach. In this case I want to use the slider to pick

问题 I am trying to rotate a group of 3D points (forming a rectangular object) created using GLMeshItem in pyqtgraph and opengl. However, I am having trouble doing this. I need to align the axes of the object (T_X, T_Y, T_Z) to the axes (Q_X, Q_Y, Q_Z). The Q axes are vectors calculated from a quaternion. Steps to reproduce: 1. Make a rotation matrix from the quaternion 2. Matrix multiplication to define the Q axes i want to rotate to 3. Translate the object origin to Q. 4. Make unit vectors and
