glFramebufferRenderbuffer 3G glFramebufferRenderbuffer attach a renderbuffer object to a framebuffer object void glFramebufferRenderbuffer GLenum target GLenum attachment GLenum renderbuffertarget GLuint renderbuffer target Specifies the framebuffer target. The symbolic constant must be GL_FRAMEBUFFER. attachment Specifies the attachment point to which renderbuffer should be attached. Must be one of the following symbolic constants: GL_COLOR_ATTACHMENT0, GL_DEPTH_ATTACHMENT, or GL_STENCIL_ATTACHMENT. renderbuffertarget Specifies the renderbuffer target. The symbolic constant must be GL_RENDERBUFFER. renderbuffer Specifies the renderbuffer object that is to be attached. glFramebufferRenderbuffer attaches the renderbuffer specified by renderbuffer as one of the logical buffers of the currently bound framebuffer object. attachment specifies whether the renderbuffer should be attached to the framebuffer object's color, depth, or stencil buffer. A renderbuffer may not be attached to the default framebuffer object name 0. If renderbuffer is not 0, the value of GL_FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE for the specified attachment point is set to GL_RENDERBUFFER and the value of GL_FRAMEBUFFER_ATTACHMENT_OBJECT_NAME is set to renderbuffer. GL_FRAMEBUFFER_ATTACHMENT_TEXTURE_LEVEL and GL_FRAMEBUFFER_ATTACHMENT_TEXTURE_CUBE_MAP_FACE are set to the default values 0 and GL_TEXTURE_CUBE_MAP_POSITIVE_X, respectively. Any previous attachment to the attachment logical buffer of the currently bound framebuffer object is broken. If renderbuffer is 0, the current image, if any, attached to the attachment logical buffer of the currently bound framebuffer object is detached. The value of GL_FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE is set to GL_NONE. The value of GL_FRAMEBUFFER_ATTACHMENT_OBJECT_NAME is set to 0. GL_FRAMEBUFFER_ATTACHMENT_TEXTURE_LEVEL and GL_FRAMEBUFFER_ATTACHMENT_TEXTURE_CUBE_MAP_FACE are set to the default values 0 and GL_TEXTURE_CUBE_MAP_POSITIVE_X, respectively. If a renderbuffer object is deleted while its image is attached to the currently bound framebuffer, then it is as if glFramebufferRenderbuffer had been called with a renderbuffer of 0 for the attachment point to which this image was attached in the currently bound framebuffer object. In other words, the renderbuffer image is detached from the currently bound framebuffer. Note that the renderbuffer image is specifically not detached from any non-bound framebuffers. Detaching the image from any non-bound framebuffers is the responsibility of the application. GL_INVALID_ENUM is generated if target is not GL_FRAMEBUFFER. GL_INVALID_ENUM is generated if renderbuffertarget is not GL_RENDERBUFFER and renderbuffer is not 0. GL_INVALID_ENUM is generated if attachment is not an accepted attachment point. GL_INVALID_OPERATION is generated if the default framebuffer object name 0 is bound. GL_INVALID_OPERATION is generated if renderbuffer is neither 0 nor the name of an existing renderbuffer object. glGetFramebufferAttachmentParameteriv glBindFramebuffer, glBindRenderbuffer, glCheckFramebufferStatus, glDeleteFramebuffers, glDeleteRenderbuffers, glFramebufferTexture2D, glGetFramebufferAttachmentParameteriv, glRenderbufferStorage Copyright 2008 Khronos Group.
