November 30: Angle is a graphic project that Google has developed for Windows computers and has now passed an important certification milestone to improve the graphics recognition of some browsers. Google launched the angle in March 2010, is a WEBGL graphics aids, borrowed new 3D graphics technology to enhance the browser experience.
Yesterday, Google programmer Vangelis Kokkevis announced that angle has passed the OpenGL 2.0 certification test suite
This is an introductory tutorial on building a web-three-dimensional view that Webgl+threejs to create simple three-dimensional graphics using Threejs and control the movement of graphics.First, create the sceneThe views we see are created by two parts, scene and camera.First, define a scene:var scene = new THREE. Scene ();Then define a camera:var camera = new THREE. Perspectivecamera (Width/height, 0.1, 10

This paper illustrates the method of WebGL using FBO to finish the cube mapping effect. Share to everyone for your reference, specific as follows:
This main record WebGL some of the basic points, incidentally also learn how to use FBO and environment mapping. First look at the effect map (need to support Webgl,chrome, Firefox, IE11).
The main realization proc
The previous chapter is the second chapter of the main study is the WEBGL implementation of the first assignment in WebGL, but not practical later by defining the attribute and uniform storage qualifiers to the JavaScript data into WebGL, the approximate process is 1, In JS to define the storage qualifier 2, in JS get canvas in JS to get hidden browser compatibil
Android supported WebGL from 5.0, and I encountered some 5.0 devices not supported in the actual development, the original chromium to run GPUs unstable or compatibility problems of the device will disable WebGL.On the Android platform you can access Chrome://gpu by installing Chorme Browser, find reset notification strategy This configuration item does turn off WEBGL support, if the value is 0x8252 it supp
1. Clear the drawing area Emptying the plot area fills the canvas with the specified background color and sets the background color using Gl.clearcolor. Gl.clearcolor (red, green, blue, alpha). The color value of OpenGL returns is 0-1. Call the Gl.clear () function to empty the drawing area with the background color specified by Clearcolor. Gl.clear (G.color_buffre_bit), cleans up the drawing area, actually cleans the color buffer (colour buffers), passing the GL. Color_buffer_bit is telling

Recently collected a variety of information, found that the WebGL Chinese network is particularly useful, very suitable for beginners: http://www.hewebgl.com/article/getarticle/50Just need to download all the packages needed, and then use Notepad can start to write code, run code I choose Google Chrome, in fact, IE is the same, purely personal beliefs.Then for the cube, the code given is very clear:Have written the site page words know HTML processing
From the beginning of writing code, the Chinese cause countless problems, this time is no exception.
There are two ways to use Chinese in WebGL:
One,
a new canvas to write Chinese , and then added to the WebGL, the advantage is not to load a specific font, the page can use what font it can use what font, and as long as the normal DOM API to refresh the DOM content,

1. Texture coordinates Texture coordinates are the coordinates on the texture image, and texture coordinates can be used to get the texture color on the texture image. The texture coordinate system in the WEBGL system is two-dimensional. To differentiate between texture coordinates and widely used x and y coordinates, WEBGL uses S and t to name texture coordinates (ST coordinate systems). The four corner c

It's a lot more painful than a normal 2d drawing.If you feel that Canvas2d native API is enough for you to toss, then WebGL will make you more helpless.Difficult to draw in the WEBGL process because it only provides the interface to operate the graphics cardWebGL is like the sister of OpenGL.
