Framebufferobject创建失败

我想创建一个FrameBufferObject，但它失败，我不知道为什么。Framebufferobject创建失败

这里是我的代码，它与以下错误消息4号线失败：

错误：

Traceback (most recent call last): 
    File "/home/julius/workspace/Bachelor/Final/Exporter/FBOtest.py", line 154, in <module> 
    fbo.mainGameLoop() 
    File "/home/julius/workspace/Bachelor/Final/Exporter/FBOtest.py", line 142, in mainGameLoop 
    self.createFBO() 
    File "/home/julius/workspace/Bachelor/Final/Exporter/FBOtest.py", line 55, in createFBO 
    glBindRenderbufferEXT(GL_RENDERBUFFER_EXT, self.depthbuffer) 
    File "/usr/lib/pymodules/python2.7/OpenGL/platform/baseplatform.py", line 335, in __call__ 
    return self(*args, **named) 
ctypes.ArgumentError: argument 2: <type 'exceptions.TypeError'>: wrong type

CODE：

self.fbo = glGenFramebuffersEXT(1) 
    glBindFramebufferEXT(GL_FRAMEBUFFER_EXT, self.fbo) 
    self.depthbuffer = glGenRenderbuffersEXT(GL_RENDERBUFFER_EXT) 
    glBindRenderbufferEXT(GL_RENDERBUFFER_EXT, self.depthbuffer) 
    glRenderbufferStorageEXT(GL_RENDERBUFFER_EXT, GL_DEPTH_COMPONENT, width, height) 
    glFramebufferReadBufferEXT(GL_FRAMEBUFFER_EXT, GL_DEPTH_ATTACHMENT_EXT, GL_RENDERBUFFER_EXT, self.depthbuffer) 

    self.texture = glGenTextures(1) 
    glBindTexture(GL_TEXTURE_2D, self.texture) 
    glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER, GL_NEAREST) 
    glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER, GL_NEAREST) 
    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA8, width, height, 0, GL_RGBA, GL_UNSIGNED_BYTE, None); 
    glFramebufferTexture2DEXT(GL_FRAMEBUFFER_EXT, GL_COLOR_ATTACHMENT0_EXT, GL_TEXTURE_2D, self.texture, 0);

我觉得'glGenRenderbuffersEXT'应该得到你想要创建的缓冲区的数量（在这种情况下可能是1），而不是GL_RENDERBUFFER_EXT作为参数。 – 2012-07-25 14:32:11

感谢它解决了我的问题！ – glethien 2012-07-25 17:26:02

glGenRenderbuffersEXT应该得到缓冲区的数目你希望创建（在这种情况下可能是1），而不是GL_RENDERBUFFER_EXT作为参数。
