First, a brief introduction to what is the browser kernel.The most important or core part of the browser is "Rendering engine", which can be translated into "interpretation engines", but we are generally used to call it "browser kernel". Responsible for interpreting Web page syntax (such as HTML, JavaScript) and rendering (displaying) Web pages. So the so-called browser kernel is the
I. Conceptual understandingIn OpenGL, GPU screen rendering is available in the following two ways:
On-Screen Rendering
means the current screen rendering, which refers to the rendering operation of the GPU in the screen buffer currently used for display.
Off-screen
Some time ago there was here (http://www.fseraph.com /? P = 661) I saw a summary of some common rendering models in real-time rendering. Recently, I also found some materials to learn about. Here is a brief summary.
1. Some Basic Concepts
Photon (photon): a particle with a wavelength and energy
Radiant Energy (radiant energy): the energy of a subset of light. Unit: (Jiao ER)
Radiant flux, radiant power:
Rendering to textures is an advanced technology in d3d. On the one hand, it is very simple, on the other hand it is very powerful and can produce many special effects. For example, the luminous effect, Environment ing, and shadow ing can all be achieved through it. Rendering to texture is only an extension of rendering to the surface. We only need to add more. Fi
Static scenarios include entity sets that generally do not change positions, such as terrain, vegetation, and buildings. Optimization of these entities is the most important part of scenario optimization. This article discusses common problems of static scenario optimization.
1 Batch Optimization
Batch is one of the most important concepts in scenario optimization. It refers to a rendering call (DP). The batch size is the number of polygon that can be
Abstract: high-resolution radar image display is an important part of Radar Computer simulation. It has high requirements on image fidelity and real-time performance. The use of programmable rendering pipeline technology for radar display system simulation can effectively achieve the layered model of radar images, make full use of the parallel processing capabilities of cptj and GP [J, greatly reducing the computing complexity of CPU. It can generate
Page rendering, usually divided into front-end rendering and back-end rendering. Front-End rendering refers to the service side return HTML frame and template, the front-end through the Ajax asynchronous request pull data rendering template, and dynamically modify the DOM to

Deferred Lighting delay IlluminationTime- lapse illumination is the rendering path with the highest fidelity illumination and shading. If you have a lot of real-time lighting, it's best to use delayed lighting. It requires a level of hardware support that is only available in Unity Pro and not supported on mobile devices. delayed illumination is one of the most advanced rendering paths to enable light and s
First, introduce the most basic rendering model: Forward rendering (Forward Rendering). There are two basic elements of rendering: objects and lights. Forward rendering refers to the application of each light to each object in turn. The process is as follows:
For each object
Rendering engineThe duty of the rendering engine is ... Rendering, that is, the content of the request is displayed on the browser screen.By default, the rendering engine can display Html,xml documents as well as pictures. It can display other types of documents through plugins (browser extensions). For example, use th

This involves the browser's kernel, which is the browser's

Ruby on Rails dynamic rendering Remote Code Execution Vulnerability (CVE-2016-0752)0x00 Overview
If your application uses a dynamic rendering path (dynamic render paths), such as rendering params [: id], using local file inclusion Sion ), remote code execution may occur. You can update Rails to the latest version or refactor your controllers to fix the vulnerabi
2-symbol Rendering
The ry is the skeleton of the map, and the graph still needs to be mapped. The ry is another huge topic. We will not expand it here to introduce the symbols and rendering directly. A symbol is a space element. It defines the color, transparency, border size, and other information of points, lines, and surface elements. rendering is a layer and
Browser Rendering Process:1. The browser starts parsing the target HTML file, and executes the stream in the top-down order.2. The HTML parser transforms the HTML structure into the underlying DOM (document Object model), which triggers the domcontendloaded event when the DOM tree is built.3, CSS parser parses CSS into Cssom (cascading style sheet object model), a tree containing only style information.4, Cssom and Dom begin to merge to form the rende
