Framebufferobject創建失敗

我想創建一個FrameBufferObject，但它失敗，我不知道爲什麼。Framebufferobject創建失敗

這裏是我的代碼，它與以下錯誤消息4號線失敗：

錯誤：

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);

我覺得'glGenRenderbuffersEXT'應該得到你想要創建的緩衝區的數量（在這種情況下可能是1），而不是GL_RENDERBUFFER_EXT作爲參數。 – 2012-07-25 14:32:11

感謝它解決了我的問題！ – glethien 2012-07-25 17:26:02

glGenRenderbuffersEXT應該得到緩衝區的數目你希望創建（在這種情況下可能是1），而不是GL_RENDERBUFFER_EXT作爲參數。
