rendering programs

Personal Summary: Reading this article takes 20 minutes, this article mainly explains the browser engine rendering mechanism.Domtree----|| ----> RendertreeCssomtree----|This is the 11th chapter of how JavaScript works.So far, the previous series of JavaScript working principles has focused on the functionality of the JavaScript language itself, how it performs in the browser, how to optimize, and so on.However, when building Web applications, it's not

1 Knowledge Reserves CPU:: Central processor, it integrates operation, buffering, control unit, including drawing function. The CPU handles objects as multidimensional graphics, textures (Bitmaps, drawables, and so on, all packaged together into a uniform texture).GPU: A CPU-like processor specifically designed to handle graphics, to help speed up grid operations, and, of course, to have the appropriate cache data (such as caching already rasterized bitmap) mechanism.OpenGL ES: A 3DAPI, cross-p

Rendering Engine The rendering engine is responsible ...... Rendering, that is, display the request content on the browser screen. By default, the rendering engine can display HTML, XML documents, and images. You can use the plug-in (browser extension) to display other types of documents. For example, use the PDF viewe

As we are not familiar with many details at the beginning, the following descriptions for the products may be inaccurate. Both GSPs and ue3 support multi-threaded rendering, that is, there is a separate rendering thread. Of course, they can all be switched through a simple method. GSPs are controlled by the r_multithreaded value, ue3 passes the command line-onethread to disable multi-threaded

Translated from: HowJavaScript works:the rendering engine and tips to optimize its performanceThis is the 11th of a series on exploring JavaScript and its building components. In the process of identifying and describing core elements, we share some of the rules of thumb used when building sessionstack . Sessionstack is a robust and high-performance JavaScript application that helps users to see and reproduce the flaws of their WEB applications in rea

program runs on the fragment processor, which controls exactly which process the GPU renders. Figure 8 shows the programmable graphics rendering pipeline.Compare the previous chapter in Figure 3. In the GPU rendering pipeline, you can see that the vertex shader controls the vertex coordinate conversion process; The fragment shader controls the pixel color calculation process. This distinguishes between ver

Using a 2D rendering to render 3D objects is nothing new, and today we are going to learn how to render the comic character-hellboy (Hellboy) original picture in ZBrush. The following is a quick recording of the Hellboy (Hellboy) modeling process: The following video shows the power of ZBrush: In fact, just set up the camera, the entire process screenshots can be, the actual use of ZBrush BPR One advantage is that can be used to render

GPU screen rendering is available in the following two ways: On-Screen Renderingmeans the current screen rendering, which refers to the rendering operation of the GPU in the screen buffer currently used for display. Off-screen RenderingOff-screen rendering, refers to the GPU in the current screen buffer to

In the previous microblog, we talked about how to prepare shader for OpenGL rendering of the cocos2dx engine. In this blog, we will use layercolor to describe the rendering process of OpenGL. 1. Create a layercolor object Add the layercolor element to the game: autolayerColor = LayerColor::create(Color4B(255, 0, 0, 255), 100, 100);layerColor->setPosition(100,100);this->addChild(layerColor); The following

Shader preparation for Cocos2dx engine 11-OpenGLES Rendering The underlying Graphics of Cocos2dx are drawn using OpenGL ES protocol. What is OpenGL ES? OpenGL ES (OpenGl for Embedded System) is a subset of OpenGL 3D graphics APIs. It is designed for Embedded devices such as mobile phones, PDAs, and game hosts. this API is defined and promoted by Khronos group. Khronos is a graphic software and hardware industry association, which focuses on open stand

In Android, the shader class is provided specifically for rendering images and some geometry.The shader class includes 5 direct subclasses, namely: Bitmapshader, Composeshader, LinearGradient, Radialgradient, and Sweepgradient. Where Bitmapshader is used for image rendering, composeshader for mixed rendering, lineargradient for linear

Forward RenderThe traditional rendering method, which you provide to the graphics card shape mesh, breaks it up into a bunch of nodes, then passes through a series of transformations and splits into fregment or pixels, rendering all the rendering done before the screen is rendered.This is fairly linear, and each shape goes through every stage of the pipeline befo

Cocos2d (v.3.0) rendering pipeline Roadmap Why (the vision) The way currently cocos2d does rendering is good but it is beginning to feel somehow antiquate and moreover it doesn't actually leverage modern multi core CPUs so popular labels on most modern tablets and mobile phones. So we want to RE design Cocos Renderer, for making it more faster Ming, elegant, scalable, flexible but still simple to use and t

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, we have to get to know canvas, because this is the base backplane for our drawing: "The c

The genre of mobile GPU rendering principles--IMR, TBR, and TbdrThe mobile GPU can only be considered as a small child, although children can be more advantageous than adults on some occasions (such as acrobatics, contortion, etc.), but there are innate differences in power, mainly in theoretical performance and bandwidth.Compared with the desktop GPU 256bit or even 384bit of bit width, 1.2-1.5ghz high-frequency memory, mobile GPU not only to share me

Since learned the Turtle module, drew a lot of simple strokes. Like Piglet Paige, Doraemon and so on, but these still do not allow people around to feel the power of Python, is still every time the force will be beaten face. It's like you painted this with turtle.Someone else took out this.What to do? In the face of the library so rich Python, not a library, we have another library. That's the Pyray library.Pyray Library IntroductionThe Pyray library was created in January 2018, although the bes

Personal Original website: http://www.phpthinking.com/archives/443 The browser must parse the Web page before it can be presented to the user. If the browser encounters an external script that is blocked by the system during parsing, it must stop parsing and download the JavaScript. Each time this happens, the browser adds a network round trip, which results in a delay in the first time the page is rendered. SuggestionsIt is recommended that you handle the JavaScript required to render the first

Now that Web apps are getting more complex and need to respond to a variety of user-triggered events, it's also inevitable that you need to add event listeners to the DOM elements on our HTML pages. We know that there are 3 ways to bind event listeners to DOM elements: 1: Page HTML: Copy Code code as follows: 2: Page HTML: Copy Code code as follows: Javascript: Copy Code code as follows: document.getElementById ("btn"). onclick = test;
