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

In a large amount of data 2D scene, to find a specific model is difficult, and can only show a part of the model, the display is not intuitive, this time can quickly build a 3D scene there is a great demand. But building 3D scenarios and relying on 3DS Max or Maya professional 3D designers to model, Unity 3D engine to do graphics rendering, this is a challenge for users! However, the HT one-stop solution provides one-stop solutions from modeling to rendering, including component rendering and da

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 last one has been described when simulating lines through a polygon, the vertex data for each vertex includes: endpoint coordinates, offsets, previous endpoint coordinates, and the last endpoint coordinates, of course, if we are drawing by index, we also include indexed arrays, The following code creates the above related data by passing a group of end points for a set of lines:?```Bk. Line3d = function (points,colors) {??? this.points = Points;??

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
