Summary of Khronos information on GDC: VULKAN,OPENXR,WEBGL,GLTFGame Developers Conference, San Francisco – The Khronos? group, an organization of leading hardware and software companies, has released major API updates and new workgroup announcements at the Game Developers Conference (GDC). This week, we will have a series of Khronos sponsored events, the Khronos group is accelerating the development of cross-platform APIs and bringing the latest hardw

color * scatter coefficient + light source intensity with color *max (0, Dot (n,l)) * Scatter coefficient + light source intensity with color *pow (dot (h,n), P)The scattering coefficient is closely related to the color of P itself. The POW is to quickly reduce the highlight size, otherwise the highlighting is not true. P is the smoothing factor.The POW (dot (h,n), P) is an improved Phong shading. Phong proposed is the POW (max (0,dot (r,e-p)), p). The difference is that when E-p and R are obtu

Repetition of something repeatedThis is already the 11th article, because just said some of the main things. Until now, even a polygon has not been

Big Data visualization platform is a three-dimensional presentation technology to represent complex information, to achieve the stereoscopic presentation of massive data. With the help of visual thinking ability of human brain, visualization technology can summarize some related visual data by mining the important relationship between data to reveal the hidden laws and trends in data, thus improve the efficiency of data usage.On the basis of solving the problems of large-scale data analysis time

The current mainstream technologies for web-vector rendering include SVG, VML, and WebGL. In contrast, VML is an older technology that, although not a standard, is widely used by earlier IE browsers (IE9) and Microsoft Office, and is now far from the browser battlefield. So there's only SVG and WebGL left to choose from. SVG is a subset of XML, adhering to the principle that a label corresponds to a data, w

WebGL uses FBO to complete the cube Paster effect (with demo source code download), webglfbo This article describes how WebGL uses FBO to implement the Cube Texture effect. We will share this with you for your reference. The details are as follows: This article mainly records some basic points of WebGL, and also learns how to use FBO and environment textures. Tak

The current webgl version is 1.0, which is actually a javascript binding of OpenGL ES 2.0, that is, JavaScript can be used to call the functions of OpenGL ES 2.0 to implement 3D rendering on the webpage. Webgl is a popular platform for desktop, mobile, and embedded systems. webgl can be used for platforms that support OpenGL ES 2.0.
