原文: Your First Polygon 在第一节中我讲解了如何创建OpenGL窗体.本节我会讲解如何创建三角形和四边形.我们会用GL_TRIANGLES来创建三角形,用GL_GUADS创建四边形. 我们会添加到第一节代码的DrawGLScene函数中.我会下面重新给出该函数的完整代码.如果你打算在上一节的代码中修改,你可以直接用以下代码替换,或者增加上一节代码没有的部分. int DrawGLScene(GLvoid) // Here's Where We Do All The Drawi…

原文: Setting Up An OpenGL Window 欢迎阅读我的OpenGL教程.我是一个热爱OpenGL的普通码农!我第一次听到OpenGL是在3Dfx刚发布他们给Voodoo I显卡的OpenGL硬件加速驱动的时候.我马上意识到我必须学习OpenGL.不幸的是,当时在网上很难找到关于OpenGL的书和资料.我花了数小时来编写可运行的代码,并且花了更多时间去发邮件和在IRC上求教别人.但是我发现懂OpenGL的人会当自己是神,并且完全没兴趣分享他们的技术.他们真的很烦! 我创建此站…

原文: Adding Colour 上一节我讲解了如何在屏幕显示三角形和四边形.本节会讲解如何上色.单色(Flat)顾名思义就是只能涂一种实心的颜色.平滑颜色(Smooth)可以在各个顶点混合三种颜色,生成各种颜色. 利用上一节的代码,我们会添加代码到DrawGLScene函数中.我还是会重写整个函数. int DrawGLScene(GLvoid) // Here's Where We Do All The Drawing { glClear(GL_COLOR_BUFFER_BIT | GL_…

参考自: http://www.yakergong.net/nehe/ 你的第一个多边形: 在第一个教程的基础上,我们添加了一个三角形和一个四边形.也许你认为这很简单,但你已经迈出了一大步,要知道任何在OpenGL中绘制的模型都会被分解为这两种简单的图形. 读完了这一课,你会学到如何在空间放置模型,并且会知道深度缓存的概念. 第一课中,我教您如何创建一个OpenGL窗口.这一课中,我将教您如何创建三角形和四边形.我们讲使用来创建GL_TRIANGLES一个三角形,GL_QUADS来创建一个四边形…

[译]Vulkan教程(30)深度缓存 Depth buffering 深度缓存 Introduction 入门 The geometry we've worked with so far is projected into 3D, but it's still completely flat. In this chapter we're going to add a Z coordinate to the position to prepare for 3D meshes. We'll use…

[译]Vulkan教程(28)Image视图和采样器 Image view and sampler - Image视图和采样器 In this chapter we're going to create two more resources that are needed for the graphics pipeline to sample an image. The first resource is one that we've already seen before while work…

[译]Vulkan教程(27)Image Images Introduction 入门 The geometry has been colored using per-vertex colors so far, which is a rather limited approach. In this part of the tutorial we're going to implement texture mapping to make the geometry look more interes…
