Multiple Transforms on mousemove jquery

阅读更多关于 Multiple Transforms on mousemove jquery

问题 Probably an easy fix, but for the life of me I can't figure it out or may be overthinking it. In short I have a div that rotatesY based on mousemove. I have that working, but I also need it to translate across the X axis as well. So I know I have to use transform: translateX(value), but not sure how to apply two transforms the best way in jquery. Thanks for the help. Fiddle link below. Also is there a way to change the rotationY directions? var $window = $(window), $box = $('#box') rotation =

Is there a transformation matrix that can scale the x and/or y axis logarithmically?

问题 I'm using .net WPF geometry classes to graph waveforms. I've been using the matrix transformations to convert from the screen coordinate space to my coordinate space for the waveform. Everything works great and it's really simple to keep track of my window and scaling, etc. I can even use the inverse transform to calculate the mouse position in terms of the coordinate space. I use the built in Scaling and Translation classes and then a custom matrix to do the y-axis flipping (there's not a

CSS3 3D转换效果

阅读更多关于 CSS3 3D转换效果

CSS3 3D 转换三维变换使用基于二维变换的相同属性，如果您熟悉二维变换，你们发现3D变形的功能和2D变换的功能相当类似。CSS3中的3D变换主要包括以下几种功能函数： 3D位移：CSS3中的3D位移主要包括translateZ()和translate3d()两个功能函数； 3D旋转：CSS3中的3D旋转主要包括rotateX()、rotateY()、rotateZ()和rotate3d()四个功能函数； 3D缩放：CSS3中的3D缩放主要包括scaleZ()和scale3d()两个功能函数； 3D矩阵：CSS3中3D变形中和2D变形一样也有一个3D矩阵功能函数matrix3d()。 1.3D位移在CSS3中3D位移主要包括两种函数translateZ()和translate3d()。translate3d()函数使一个元素在三维空间移动。这种变形的特点是，使用三维向量的坐标定义元素在每个方向移动多少。随着px的增加，直观效果上： X：从左向右移动 Y：从上向下移动 Z：以方框中心为原点，变大从上图的效果可以看出，当z轴值越大时，元素也离观看者更近，从视觉上元素就变得更大；反之其值越小时，元素也离观看者更远，从视觉上元素就变得更小。例子： height: 300px; float: left; margin: 15px; position: relative;

CSS3(3)---2D变形(transform)

原文: CSS3(3)---2D变形(transform) CSS3(3)---2D变形(transform) 2D变形是CSS3中具有颠覆性的特征之一，它常用的属性有: 移动 (translate)、缩放 (scale)、旋转 (rotate)、倾斜 (skew)。一、2D变形语法 1、移动 (translate) 移动的属性: translate translate(x,y)水平方向和垂直方向同时移动（也就是X轴和Y轴同时移动） translateX(x)仅水平方向移动（X轴移动） translateY(Y)仅垂直方向移动（Y轴移动）比如设置为: transform: translate(50px,60px); /* 水平向右移动50px 和垂直向下移动60px*/ 运行结果说明从上面运行结果可以看出两点 1、移动的原点默认是最左角上的位置。 2、px取正数代表向右或者向下。Px为负值,那就变成向左或者向上。 2、缩放 (scale) 缩放的属性: scale scale(X,Y)使元素水平方向和垂直方向同时缩放（也就是X轴和Y轴同时缩放） scaleX(x)元素仅水平方向缩放（X轴缩放） scaleY(y)元素仅垂直方向缩放（Y轴缩放）说明 scale默认值为1,设置0.5代表缩小一倍,2代表放大一倍。比如设置为: transform:

How can I apply an SVGMatrix to an array of points?

阅读更多关于 How can I apply an SVGMatrix to an array of points?

问题 Are there built-in libraries to multiply a vector of points by an SVGMatrix? I have an SVG drawing that has been scaled, and I want to annotate that drawing in its original coordinate system with a line that has a fixed width in screen space. (I.e. the line should not change width when zooming in or out, but lines in the image do, of course.) So, my approach is to transform the image inside a , and then take my array of points and apply the same transformation, then create a new path object
