Summary of definitions and usage of axes

The perspective property and the associated Perspective-origin attribute are all used to control the distance on the axis in the 3D graphics space, so let's share the example method of setting the 3D transform distance for the perspective property of the CSS3. Of course, you'll also talk about Perspective-origin's usage: The Perspective attribute is critical for 3D deformation. This property sets the viewer's location, maps the visual content to a frustum, and then throws it onto a 2D view plane. If you do not specify a perspective, all points in the z-axis space are tiled into the same 2D view plane, and the depth of field concept does not exist in the transform results. The above description may be difficult to understand some, in fact, for the perspective property, we can easily understand as the distance, used to set the user and the element 3D space between the z plane. And its effect is determined by his value, the lower the value, the user and 3D space z plane distance closer, the visual effect is more impressive; conversely, the greater the value, the farther the user is from the Z-plane of the 3D space, the less visual effect. In 3D variants, for some variants,

1. Share CSS3 's Perspective attribute set example method for 3D transform distance

Introduction: Perspective Properties and related Perspective-origin properties are used to control the distance on the axis in the 3D graphics space, so we will explain the CSS3 perspective property to set the 3D transform distance method, Of course, we'll talk about the use of Perspective-origin later:

2. HTML5 Canvas coordinate conversion, hatch, gradient and shadow

Introduction: Previous article we learned some basic drawing of the canvas below let's look at some of the relevant operations axis transformation in our canvas the default axis is the same as the browser axis x positive half axis facing right y positive half axis down but we can manually set the canvas axis transformation first or the canvas and the brush var canvas = Document.getelement

Introduction: Problems with histogram in jpgraph [img=http://img.my.csdn.net/uploads/201205/31/1338473872_1500.png img] This is my bar chart, the horizontal axis divided by 50 equal points, and 50 bars are used, but the widths of these bars are too narrow to correspond evenly to the horizontal axis. How can they exactly correspond to the 0-2,2-4,4-6 ... (i.e. evenly dispersed on the axis?) ) This

5. Can rotate in CSS transform be rotated on a diagonal axis?

Introduction: In the div named in, with the rotate ad for the axis "oblique rotation" can be achieved? As I try, the Transform-origin property seems to be able to offset the axes only, but there is no way to rotate them, so the axes of rotation are horizontal or vertical ... Rotatex () and Rotatey () are also not feasible ... How do you achieve this rotation?

6. Can I generate a Word document with a drawing with axes in HTML?

Introduction: The graph is drawn with jquery flot. The purpose of this is to turn the HTML page (not necessarily JS generated, with a drawing with axes) to the word page. At present, both methods do not seem to work: the first is to use the Phpword library, but this library seems to have not given the method of the drawing table. ...
