webgl course

Note: The article is translated from http://wgld.org/, the original author Sambonja 広 (doxas), the article if there is my additional instructions, I will add [Lufy:], in addition, The WEBGL research is not deep enough, some professional words, if the translation is wrong, you are welcome to correct. The results of this demo runPoint LightThe last introduction of the high-color and complementary color coloring.Using complementary coloring, you can rend

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

, there is an interesting phenomenon here, we obviously follow the translation of the Py, rotation XZ and the order of scaling SF as the input of the row matrix multiplication, but in the later process text description, I follow the inverse to explain. What is this for? Because the matrix is stored in a two-dimensional array, WebGL passes through the shader in the process of passing the matrix to the shader , that is, the shader is processed by the da

I am preparing to graduate this year's senior students, is fast into the social programming small white one, the university during their own on-line collection of information on the WEBGL related basic courses, now here to share my study with the books, hope to help many want to learn but do not know how to do the people, we progress together.1. First, for people with a certain JavaScript base, you can read the [JavaScript authoritative Guide (sixth E

I started directly using the 3d model in the encapsulated function, resulting in the function is not known to use the parameters are what to do, and do not understand how the 3d model is formed, and then re-read the front of the "model base", only to know the original 3d model used a face, the most basic is the triangular surface, After the complex surface is formed by a pluralit

four-dollar number Last time, we used the four-number to rotate the vector, using the four-dollar number holding the rotation information and its conjugate four-dollar number to calculate.This site uses the algorithm library Minmatrixb.js, has encapsulated the rotation three-bit vector function, that is the QTNIV.TOVECIII function.Within this function, the conjugate four-dollar number is automatically generated and calculated based on the parameters. Passing in three parameters, holding the fou

Write the frontWebGL is a real hassle. 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. Sister is a process-oriented so sister is the same!(I am my sister)For this,

Unity uses Websocket to implement WebGL online games (no plug-ins) and websocketwebglOpening Before Unity supports WebGL, You need to convert it into a Flash Platform for publishing for web games, but there are many things that need special processing in the middle. Or, if you do not use Flash, you need Unity WebPlayer. This is a Web plug-in. You must install this plug-in your browser before running the too

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

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
