Basic ideasThe previous article briefly describes the WebGL drawing line bug, an article that will cover work around to solve the problem.The last article at the end of a simple way to solve the idea is to use the triangle to simulate the line.For example, a line segment consisting of two endpoints is used when plotting line with only two endpoints specified, and if a segment is modeled by a triangle, at least two triangles are required, such as:Two t

Because of the collection software of Beijing street view in the early stage, there were a lot of street view pictures in the hand; and The Amazing effects of google Street View and soso street view gave rise to the idea of a small test, why don't I turn the image into a 3D street view and put it online. So I began to collect relevant information. After five days of trial, I finally achieved initial results; First of all, thanks to http://www.hiwebgl.com /? P = 42

HT for Web custom 3D model of WebGL application, htwebgl Many of my friends asked how the 3D table design model in the article "HTML5 Web Client's five offline storage methods summary" was generated by importing the table design model designed by 3dmax, and then import it to the HT for Web System in obj format for control. This method is especially suitable for application scenarios of complex models, however, many applications of the monitoring syst

HTML5-based WebGL combined with Box2DJS physical engine application In the previous article, we presented the 3D pathfinding effect of a * Search Algorithm Based on HT for Web. In this article, we will use HT for Web 3D to present the collision effect of the Box2DJS physical engine, as shown in the previous article, Box2DJS is only a two-dimensional physical engine for plane collision, but it also allows users to experience collision effects more intu

Drawing two-bit graphics on a canvas requires the following three steps:1. Get 2. Request the "drawing context" of a two-dimensional graphic to the element3. Call the corresponding drawing function in the drawing context to draw a two-dimensional graphicUse the method supported by the context to draw two-dimensional graphics:RGB format, RGBA format, and finally transparencyCtx.fillrect (120,10,150,150); The first two is the x, y coordinate behind the length and width2016-7-3

Sky Box add can make the scene of the model is very beautiful, and its principle is very simple, I believe that after reading the code below can understand.When it comes to the two methods of the sky box, it is more like two ways of writing, respectively, using the two methods of texture loading: loadtexture and Loadtexturecube.Special Note: The order of the pictures"Method One"var imageprefix = "images/";var directions = ["Posx", "negx", "Posy", "Negy", "Posz", "Negz"];var imagesuffix = ". jpg"

1.requestAnimationFrame (func)Request that the browser callback the function func at some point in the future to complete the redraw, we should start the request again at the end of the callback function. Parameters:Func: Specifies the function to be called at some point in the future. The function will receive a time parameter in the future to indicate the timestamp of this call. Here's an example:var function (){ ... Requestanimationframe (tick);}2.cancelAnimationFrame (RequestID)Cancel

. When the code is not under my control. We have to explain some gratuitous nonsense, which leads to unnecessary trouble.Simply. Eliminate the problem in the bud and try to stay away from the whirlpool as well.An independent function in which the input parameter is the image before mirroring.

There are only three modes of movement in the 3D World: move, rotate, zoom out.The use of the settimeout function can be used to achieve repeated cyclic processing, then what is the specific approach?The first argument to the SetTimeout function is the function that is called, and the second parameter is how long it takes (milliseconds) to call this function. If the first parameter is specified as the function that is currently running, then a continuous loop can be implemented.? function A is c
