3d rendering library

same purpose, Microsoft also defined a set of parallel interfaces similar to OpenGL, called Direct 3D.This is the origin of OpenGL and d3d. The difference is that OpenGL only contains the 3D acceleration interface, while DirectX also contains the Sound Interface direct sound in addition to d3d, and then the input and output device interfaces, collectively referred to as DirectX. No matter OpenGL or d3d, their workflows are similar.We will discuss d3d

Recently engaged in a game to meet the shortest path of the general game problem, happened to see the old colleague wrote the shortest path of the 3D computer room patrol line article, a qixing based on the HT for Web write a * algorithm of WEBGL 3D rendering, algorithm based on open source https://github.com/bgrins/ Javascript-astar JavaScript implementation, in

Because of the collection software of Beijing street view in the early stage, there were a lot of street view pictures in the hand; and The Amazing effects of google Street View and soso street view gave rise to the idea of a small test, why don't I turn the image into a 3D street view and put it online. So I began to collect relevant information. After five days of trial, I finally achieved initial results; First of all, thanks to http://www.hiwebgl

The 3D rendering API of NaCl uses gles2.0, which is well understood because it is already recognized as a cross-platform standard. Mobile phones, tablets, webpages, and PCs can all be used. Even on windows, there are some DX9-based gles2.0 implementations, such as angle. sometimes I really want to think that upgrading an operating system version like M $ will eliminate an API. It is better to use the standa

What is rendering) A simple understanding of rendering may be like this: it is to convert the description of a 3D object or a 3D scene into a two-dimensional image, and the generated two-dimensional image can well reflect a 3D object or a

You can consider using multi-stream technology to make diffuse data a separate stream. Original Multi-layer terrain texture hybrid shadow rendering method Because the terrain is very large and requires a large number of vertices, it often occupies

, the basic elements are converted to two-dimensional fragment)Fragment indicates the pixels that can be rendered to the screen. It contains location, color, texture coordinates, and other information. These values are calculated by interpolation of the vertex information of the element. These parts are then sent to the part coloring tool for processing. This is a qualitative process from vertex data to pixels that can be rendered on the display device. Fragment shader: The bitwise colorant impl

the math problems involved can be seen by the Wolfram Mathworld:the Web's most extensive mathematics Resource. Code: such as the source code of the engine (Unreal, Klayge, etc.), open source demo/example (in recent years the Direct3D official example also has some paper implementation), Unity's Asset store, Shadertoy beta and so on. Engineering problems are usually not a single technical problem, need to consider the integration of multiple systems, as well as the work flow and other aspect
