CS (); // list settings clears all selected elements }});All code ends!SummarizeThis 3D Intelligent building monitoring system is very simple, for the technical staff is completely no challenge, the main work in the art, so that, if you want to add more complex requirements, technicians can devote themselves to

up position, and use the LookAt function, next create a renderer, specify the background color and width, height, and then create an object , the renderer needs to be added to the document.body, followed by an animation, and then run. However, we can find that although the above code is done, but the encapsulation is not good, we can try to encapsulate it in a function, as follows:"en">"UTF-8"> As shown above, through the function encapsulation, the program logic is better, and only exposes the

HTML5-based WebGL design of the tower 3D Game Here we will construct a HTML5 + JavaScript Based on HT for Web to implement the tower of death game. Http://hightopo.com/demo/hanoi_20151106/index.html For details about the game rules and recursive algorithms of tower of Hanoi, see http://en.wikipedia.org/wiki/tower_of_hanoi. Now that you know the rules and algorithms of the tower, you can create elements. Using existing HT for Web (http://www.hightopo.c

HTML5-based WebGL combined with BOX2DJS physics engine application In this article, we present A * search algorithm 3D pathfinding effect based on the HT for Web, which we will use HT for Web 3D to present the collision effect of the Box2djs physics engine, in fact Box2djs is just two dimensional plane collision physics engine, But also through the 3D rendering can give people a more intuitive experience of the collision effect, the final example eff

Today there is no continuation of the previous story, interspersed with a small episode, WebSocket real-time data communication synchronization problem, today we are not very pure WebSocket related knowledge, we use the WebGL 3D topology map to present an interesting Demo. Let's take a look at what this real-time data communication is all about.Let's talk about the idea of the Demo, first I want to have a 3D topology diagram component, create several

screen) to black: The 0x color used by ThreejsRenderer.setclearcolor (0x000000);Scenes (Scene)The objects added to the Three.js are added to the scene, so it is equivalent to a large container. Generally speaking, there is no complicated operation in the scene, it is instantiated at the very beginning of the program, and then the object is added to the scene.var New Three. Scene ();Cameras (camera)Before we introduce the camera settings, let's start with a simple understanding of the coordinate

Type of camera: There are two cameras in WebGL: a positive projection camera and a perspective camera1. Positive projection camera Orthographiccamera: Similar to the angle of view in engineering drawings, ignoring the near and far distance, the proportion of objects near and far is constant, more used in scientific research, engineering drawing applicationOrthographiccamera (left, right, Top,bottom, near, far)Left: the vertical distance from the cente

Through the WebGL technology can achieve some cool 2d/3d graphics, WebGL and Flash, it does not need to install Plug-ins to run in the mainstream browser, because more than 3D effect, designers have a creative inspiration, through this technology to achieve a very cool three-dimensional perspective, Or with JS to make some cool animation or games, to enhance the interaction between visitors and the site exp
