webgl map

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. something that repeats repeatedly.This is the 11th article, because only said a few basic things, so far even a polygon has not been drawn out. Ah ah ah .

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

The WEBGL program uses both HTML and JavaScript on the screen to create and display three-dimensional graphics. The newly introduced Because the Get the WebGL drawing contextvar gl = getwebglcontext (canvas, true);Getwebglcontext (element, [debug]);Gets the WebGL drawing context, or if the Debug property is turned on, an error message is displayed in the console

Two-and three-dimensionalThree-dimensional space-we live this reality of the world is a three-dimensional space.In the three-dimensional world, everything

3D "ELASTIC" layout based on HTML5 WebGL Molecular force (molecular force), also known as the Inter-molecular force and Van devis force, refers to the interaction between molecules. When the two molecules are far apart, they are mainly attractive. This force is mainly derived from the interaction of one molecule due to the polarization of the polar moment of the other molecule that rapidly changes over time; when the molecules are very close, the excl

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,

Note: The article is translated from http://wgld.org/, the original author Sambonja 広 (doxas), the article assumes that I have additional instructions, I will add [Lufy:]. Other than that. My own WEBGL research is not deep enough, some professional words. Suppose the translation is wrong. You are welcome to correct me. the meaning of the vertex attributeIn the last article, we introduced the generation of shaders, the compilation, the generation of pr

of six polygon color and map can only be the same, drawing performance than the default Hexahedral high;As shown, the left side is shape3d set to box, the right side is the default six-face body, two nodes are mapped on the upper surface, but from the effect of the Shape3d set to box node directly ignores the map setting on the upper surface, which should also be documented above, box The color and

-dimensional dynamic and other technologies to achieve three-dimensional scene dynamic visual monitoring, more effective identification, analysis, It has become the trend and direction for the visual development of video surveillance platform to exploit the public application of the effective information service of massive data. At present, in the monitoring industry, Hoi Hong, Dahua and other monitoring industry leaders can be based on such a way to plan the layout of cameras in public places,

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
