Renderbuffer objectswere introduced to OpenGL after textures as a possible type of framebuffer attachment, Just like a texture image, a renderbuffer object is an actual buffer e.g. an array of bytes, integers, pixels or whatever. However, a renderbuffer object can not be directly read from....
FBO提供了一种高效的切换机制;将前面的帧缓存关联图像从FBO分离,然后把新的帧缓存关联图像关联到FBO。在帧缓存关联图像之间切换比在FBO之间切换要快得多。FBO提供了glFramebufferTexture2DEXT()来切换2D纹理对象和glFramebufferRenderbufferEXT()来切换渲染缓存对象。

创建RenderContext类 具体实现与d3d差不太多,主要是创建设备。 不过要注意GetOrCreateSharedOpenGLContext方法,他是静态的, 我们在初始化wgl时需要一个窗体,所以我在这里让所有绘制控件都使用一个窗体。 View Code 创建Framebuffer类 这里主要用d3d创建一个Surface, ...

之前用到的DepthBuffer,ColorBuffer,stencilBuffer都属于FrameBuffer的一种,在OpenGL中我们可以自定义我们想要的FrameBuffer。 想要将数据存入链接至Framebuffer有两种做法,Texture和RenderBuffer分别对应, glFramebufferTexture2D(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0,GL_TEXTURE_2D, texture, 0); glFramebufferRenderbuffer(...
