Introduction of Three.jsThree main elements: scene, camera and rendererScene: The container in the animation, all objects exist in a scene, three-dimensional scenes similar to the canvas in a two-dimensional animationCamera: A visual angle that shoots a scene and can capture a different scene by switching position and angleRenderer: Renders the contents of the camera to the browser, and the end user sees the camera's scene through the browser.The relationship between themCreate a scene: var scen

1. WebGL WaterThis incredible demo is as fluid as could believe. Raise and drop the ball into the water to see realistic, beautiful splashing of the water. You can also just click on the water to see it ripple away. I ' m completely awestruck at how realistic and smooth the animation are in this excellent WebGL demo. Unreal.View Demo2.

Today IOS8 finally officially released, upgrade the equipment on hand for me the most important thing is to test the WebGL 3D is really able to run the Apple system, ran a number of HT for the web 3D examples are very smooth, than Android just support WebGL when much better, basically haven't found any problem , Apple is still worthy of affirmation, do not do, to do the real can use

In the process of using WEBGL, we often want to texture and post it on the surface to displayFor more accurate edge detection, we have to use grayscale shader, fuzzy shader, edge shader for processing, and each processing object is the last processing of texture, This will overwrite and save the processed results.In the many WebGL libraries, there is a direct option redertotarget to render the shader proces

Based on the previous OpenGL rendering principle, these two weeks have come into contact with some of the WebGL drawing of some content, because just getting started, a lot of things are very obscure, so deliberately spent a small half a day to tidy up, hereby recorded.OneCanvas and brushes: Create canvas get WEBGL contextBefore we start the WebGL drawing story,

The babylonjs of WebGL is carried out in an accidental situation, primarily to satisfy the individual's desire for full stack development.So, let's start with a brief talk about the process. What is WebGL? WebGL is an HTML-based client page technology that implements rendering based on the HTML5 canvas (canvas) deployment. Can complete the game development, the

THREE. js-the beauty of mathematics. There are webgl curve animations made by Daniel abroad ., Wuji (http://blog.csdn.net/omni360) This article follows the "signature-non-commercial use-consistency" creation public agreement Reprinted please keep this sentence: Wuji-this blog focuses on Agile development and mobile and IOT device research: data visualization, GOLANG, Html5, WEBGL, THREE.

Based on WebGL's cool element background ripple jQuery special effect, webgljqueryJquery. ripples is a jQuery special effect plug-in with extremely cool effects based on WebGL. With powerful WebGL, The jQuery plug-in can add a water wave layer to a specified element to produce cool water ripple effects and interact with it with the mouse. WebGL is a 3D drawing s

Browsers are becoming more powerful today, and these features may be called directly through JavaScript. You can easily add audio and video with HTML5 tags, and you can create various interactive components on the HTML5 canvas. Now there's a new member in this feature set that supports WebGL. With WebGL you can directly use the computing resources of the graphics card, create high-performance two-dimensiona

OpenGL 7th ~ Chapter 8 Cropping, raster, and hidden area Elimination Raster is the process of processing objects into fragments. Two things that must be done. First, make each set object pass through the graphic system. Second, assign a color value to each pixel to be displayed in the color cache. Four main tasks of the graphic rendering system Modeling-> geometric processing... Modeling: obtains a set of vertex data that represents the geometric object. Geometric processing: acts on vertex data

This PPT is a summary of my research on webgl with some examples: Because the csdn blog does not contain attachments, please download the following two resources (the content of the following two resources is the same, and the content of one resource contains the video part, which is relatively large, and you can download it by yourself based on the network speed and time): Resources that contain videos: http://download.csdn.net/detail/withasi/379
