can cause performance costs:Out-of-screen rendering does not imply software drawing, but it means that the layer must be displayed in arendered (either CPU or GPU) in the offscreen context. Therefore, when using off-screen rendering, it is very easy to cause performance consumption, because in OpenGL, the off-screen renderin
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

When it comes to Web performance, the front-end engineers naturally react to Yahoo's 30+ optimization rules. These rules can load a Web page from the original seconds or even less than more than 10 seconds to 3s or even 1s. When a full interface is displayed to the user, the content is communicated to the user through different fonts, images, and multimedia. It is equally important for users to see web pages within 1s and to use them for a few minutes or even dozens of minutes to stay on the web

(This phenomenon can also be seen in Windows 7 under IE9 using Microsoft Jas font). It's not scientific. After reading this article, you will understand.
Why the same font on Mac OS appears to look better than on Windows. I've never been able to figure this out, but yesterday I saw an article about font

Graphic programming is the magic behind video games, movies and scientific simulation simulations. Every explosion, particle, and glare you see on a computer screen is handled using a video card. In addition, every pixel you see is achieved through GPU rendering and graphic programmer software, because modern operating systems use GPU rendering. This
Overview Introduction
Layered rendering is actually a very traditional problem, and many friends who have participated in animation or film projects have used layered rendering to solve the final rendering problem. This topic mainly introduces the basic concepts of layered rendering and some extended discussions.
So
Unity renders base rendering 1. What is rendering?All we can see is the need to render.For example: Sky box, scene model, character model, special effects ...If there is no rendering, the game world will be a piece of darkness.2.

Graphics can be rendered in two categories: software rendering and hardware rendering. Software rendering relies on the CPU to calculate various coordinates and draw, mainly to occupy memory, hardware rendering is GPU-based, mainl

These APIs are very important for understanding libhwui.Text APIsThe application mainly uses the following four APIs to layout and draw text:Android. widget. textView: A view android used to process layout and rendering. text. * create a set of formatted text and layout classes for android. graphics. paint is used to measure text (to measure text) android. graphics. canvas is used to render text (to rend
Rendering is usually accompanied by a 3D scenario that requires computing the performance of light, such as refraction and reflection. Basically, the performance is calculated by the CPU. Therefore, the multi-core CPU has a great advantage in rendering speed, while the graphics card only takes the CPU the calculation result is displayed on the screen. There is basically no difference in the quality of grap
