windows/mfc程序中使用OpenGL的多重采样功能 学过opengl基础的人都知道,打开混合功能并调用glEnable(GL_POINT_SMOOTH)/glEnable(GL_LINE_SMOOTH)可以实现模型点/线的反走样功能,非常简单且效果不错。 但是对于实心多边形的支持却没有那么简单,单纯的调用 glEnable(GL_POLYGON_SMOOTH)发现并没有效果。 OpenGL对于多边形...

The parameter texture can be read using linear texturing to provide smooth transitions between regions of grass and can be a fairly low resolution. If you want to make your grass wave in the wind or get trampled as hoards of armies march across it, you cananimate the texture by updating ...
One could shoot a large number of rays for each point in space to determine its amount of occlusion, but that quickly becomes computationally infeasible for real-time solutions. In 2007, Crytek published a technique called screen-space ambient occlusion (SSAO) for use in their title Crysis. ...
glutKeyboardFunc(void(*func)(unsigned charkey,intx,inty))和glutMouseFunc(void(*func)(intbutton,intstate,intx,inty))允许您链接键盘键或按下或释放键或鼠标按钮时调用的例程的鼠标按钮。 当鼠标按键被移动时,glutMotionFunc(void(*func)(intx,inty))会注册一个例程来回调。

glEnable(GL_POINT_SMOOTH); glEnable(GL_LINE_SMOOTH); glEnable(GL_POLYGON_SMOOTH); 3.5.4 多重采样 例如,为了请求一个多重采样,完全颜色,带深度的双缓冲帧缓冲区,我们可以调用 glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH | GLUT_MULTISAMPLE); ...
glUniformBlockBinding来完成,其中第三个参数是binding-point,这里同样选择了第0个binding-point——这样OpenGL端的UBO和GLSL端的uniform block就联系在一起了。Shader中需要使用block中的uniform变量时,就会索引到对应的UBO中对应的位置的数据。 所谓
Basic and verbose example for getting a colored triangle rendered to the screen using Vulkan. This is meant as a starting point for learning Vulkan from the ground up. A huge part of the code is boilerplate that is abstracted away in later examples. ...
