What is OpenGL? 什么是 OpenGL? 在最基本的层面上,OpenGL 是一个允许程序员与图形硬件通信的软件接口(software interface)。当然,OpenGL 的内涵远不止于此,你会很高兴知道本书将为你讲解 OpenGL 的更多细节。不过,在我们动手开始编码之前,你需要了解一下计算机图形学(Computer Graphics)和 OpenGL 的历史。 在这篇...
在 OpenGL 中,这些对象被称为顶点缓冲对象(Vertex Buffer Objects,VBO),而在 Direct3D 中,它们被称为顶点缓冲区(Vertex Buffers)。您将在以后的章节中了解到更多有关 VBO 的信息,该章节将向您介绍 VBO 以及它们为何如此快速的原因。 参考:缓冲区 在计算机科学中,缓冲区是内存中存储临时数据的地方。当我们用完这...
On the most fundamental level, OpenGL is a software interface that allows a programmer to communicate with graphics hardware. Of course, there is much more to it than that, and you will be glad to know that this book explains the finer details of OpenGL. But before we get our hands dirty...

What is the maximum length of a HiLog record? Is it configurable? Why is private displayed in HiLog information when the format parameter %d or %s is specified? What should I do if the hilog.debug log cannot be printed? How do I control the log output level based on the environme...
What should I do if there are three devices that cannot be identified in a single device manager? What should I do if the hdc server and client versions are inconsistent? What should I do if "Kill server failed" is displayed? Is there a directory that can be written into an executa...
QMC (Quasi-Monte Carlo Sampling): QMC is now used for random numbers in raytracing. Copy and Paste UVs: Added option to copy UVs from one object and paste them to another, as long as the geometries have the same vertex count. From the Scenegraph context menu, select Edit > Copy UVs ...

Vertex processing.The graphics card processes vertices, which are the points that define the shape of 3D objects. It transforms these vertices into screen coordinates, applying transformations like scaling, rotation, and translation to position the objects correctly in the 3D space. ...
What is the difference between vertex shaders and pixel shaders? Vertex shaders and pixel shaders are both types of programmable shaders used in computer graphics, but they serve different purposes. Vertex shaders are responsible for manipulating the geometry of three-dimensional (3D) objects, su...
