rotation

问题 Trying to write part of the python code in Maya to extract the face from object then move it and rotate it. I tried parameters of polyChipOff itself, tried xform and move and rotate functions. Problem is the same. If rotation is after translation face rotates against the previous position not the current one. Am I understand some concepts completely wrong? Code below shows the problem. Simply create a pCube and start the script. From my perspective this code should move face away and then

问题 I'm working on a rotation animation in Kotlin and I after each Animation I want to set a net rotationStart and rotationEnd where the rotationStart value initially should be set = 0 and afterwards assumes the value of the rotationEnd value after each rotation val rand = Random() var rotStart : Float = 0f var rotEnd : Float = rand.nextFloat(100f) Setting up the rotation like this: var rotateAnimation = RotateAnimation( rotStart, rotEnd, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO

问题 Im trying to rotate a button (with) CSS3 styles (gradient) by 90degress and apply it on absolute right:0px position. That button is "About us". It seems like there are 2 problems. First is that the button element doesn't go all the way to the right (like I want it) and it seems that the problem is in CSS3 rotation that still thinks 150px width. If I disable the rotation, the element is aligned to the right screen perfectly, with no space left out. Also I found that in Google Chrome, when i

问题 I have image inside the JPanel . I would like to rotate the image. Is it possible to rotate the JPanel using Graphics , Image is rotatable, Just out of curiosity is it possible to rotate JPanel ? 回答1: Yes! This is possible and fairly straightforward too. I haven't done rotations but I have done other affine transformations (scaling the entire GUI up and down) very successfully on a project. I cannot see why rotations should be any different. Instead of trying to scale each component use the

问题 I want to rotate my player when device is rotating.

When i try just change my device orientation for making full screen, player first player draw half of view,after it go to normal fullscreen mode[! 回答1: I found the answer myself, this

问题 From this answer; https://stackoverflow.com/a/34060479/1493455 I have made some code that should rotate a point around an origin point. The origin is at 0,0,0. Instead of my rotations being yaw pitch roll , I have xrot yrot and zrot which are degrees (0-360). A rotation around the X axis results in the object pitching back and forth, a rotation around the Z axis results in it rotating as if it was the yaw of the object. I think I messed up somewhere in translating the values, but I can't seem

问题 I am trying to rotate a rectangle without using the rotate function, but instead using a matrix..I know how to rotate a line using a matrix but all my attempts to rotate a rectangle have failed. I dont think this is use full but heres is my code that rotates the line. float[][] rotation; float[] position; float theta = 180; float pointX; float pointY; void setup() { frameRate(60); size(600, 600); pointX = 0; pointY = 0; rotation = new float[2][2]; position = new float[8]; } void draw() {

问题 I am trying to simulate a bendable arm using SpriteKit. I have an upper arm SKShapeNode and a lower arm SKShapeNode . How would I rotate the lower arm so it rotates at the elbow instead of rotating on itself? Here is my straight arm with the upper arm being tan colored and the lower arm being cyan colored. This is what it looks like after a -90 degree rotation on the lower arm How would I simulate the lower arm being connected to the upper arm at the elbow? I've tried multiple SKConstraint s

问题 I am working on an app (my first one), which is basically a TabBar app. To be more precise there are: - a login view controller - a tab bar controller (when login is done) - a landscape view controller that is used when the first itel of the TabBar is switch from Portrait to Landscape. So, when I am in the first tab, I need to be able to move to landscape view to display some other data. In my tab bar controller, I have implemented those methods: - (BOOL)shouldAutorotateToInterfaceOrientation

问题 I try to rotate my image when I click(using Pixastic) but I can only rotate 1 time, how can I go on rotating each time I click to the image $('#tok').click(function() { $("#tok").pixastic("rotate", {angle:90}); }); 回答1: I have NOT used Pixastic before. But, I believe, everytime the image is clicked , you have to increase the angle 90 . First Click -> 90 Second Click->180 Third Click ->270 Fourth Click ->360 Fifth Click ->90..etc Updated: It seems Pixastic remove the image first and insert it
