GL_FRAMEBUFFER is equivalent to GL_DRAW_FRAMEBUFFER. attachment Specifies the attachment point of the framebuffer. attachment must be GL_COLOR_ATTACHMENTi, GL_DEPTH_ATTACHMENT, GL_STENCIL_ATTACHMENT or GL_DEPTH_STENCIL_ATTACHMMENT. texture Specifies the texture object to attach to the framebuffer attachment point named by attachment. level Specifies the mipmap level of texture to attach. glFramebufferTexture, glFramebufferTexture1D, glFramebufferTexture2D, and glFramebufferTexture attach a selected mipmap level or image of a texture object as one of the logical buffers of the framebuffer object currently bound to target. target must be GL_DRAW_FRAMEBUFFER, GL_READ_FRAMEBUFFER, or GL_FRAMEBUFFER. GL_FRAMEBUFFER is equivalent to GL_DRAW_FRAMEBUFFER. attachment specifies the logical attachment of the framebuffer and must be GL_COLOR_ATTACHMENTi, GL_DEPTH_ATTACHMENT, GL_STENCIL_ATTACHMENT or GL_DEPTH_STENCIL_ATTACHMMENT. i in GL_COLOR_ATTACHMENTi may range from zero to the value of GL_MAX_COLOR_ATTACHMENTS - 1. Attaching a level of a texture to GL_DEPTH_STENCIL_ATTACHMENT is equivalent to attaching that level to both the GL_DEPTH_ATTACHMENT and the GL_STENCIL_ATTACHMENT attachment points simultaneously. If texture is non-zero, the specified level of the texture object named texture is attached to the framebfufer attachment point named by attachment. For glFramebufferTexture1D, glFramebufferTexture2D, and glFramebufferTexture3D, texture must be zero or the name of an existing texture with a target of textarget, or texture must be the name of an existing cube-map texture and textarget must be one of GL_TEXTURE_CUBE_MAP_POSITIVE_X, GL_TEXTURE_CUBE_MAP_POSITIVE_Y, GL_TEXTURE_CUBE_MAP_POSITIVE_Z, GL_TEXTURE_CUBE_MAP_NEGATIVE_X, GL_TEXTURE_CUBE_MAP_NEGATIVE_Y, or GL_TEXTURE_CUBE_MAP_NEGATIVE_Z. If textarget is GL_TEXTURE_RECTANGLE, GL_TEXTURE_2D_MULTISAMPLE, or GL_TEXTURE_2D_MULTISAMPLE_ARRAY, then level must be zero. If textarget is GL_TEXTURE_3D, then level must be greater than or equal to zero and less than or equal to log2 of the value of GL_MAX_3D_TEXTURE_SIZE. If textarget is one of GL_TEXTURE_CUBE_MAP_POSITIVE_X, GL_TEXTURE_CUBE_MAP_POSITIVE_Y, GL_TEXTURE_CUBE_MAP_POSITIVE_Z, GL_TEXTURE_CUBE_MAP_NEGATIVE_X, GL_TEXTURE_CUBE_MAP_NEGATIVE_Y, or GL_TEXTURE_CUBE_MAP_NEGATIVE_Z, then level must be greater than or equal to zero and less than or equal to log2 of the value of GL_MAX_CUBE_MAP_TEXTURE_SIZE. For all other values of textarget, level must be greater than or equal to zero and no larger than log2 of the value of GL_MAX_TEXTURE_SIZE. layer specifies the layer of a 2-dimensional image within a 3-dimensional texture. For glFramebufferTexture1D, if texture is not zero, then textarget must be GL_TEXTURE_1D. For glFramebufferTexture2D, if texture is not zero, textarget must be one of GL_TEXTURE_2D, GL_TEXTURE_RECTANGLE, GL_TEXTURE_CUBE_MAP_POSITIVE_X, GL_TEXTURE_CUBE_MAP_POSITIVE_Y, GL_TEXTURE_CUBE_MAP_POSITIVE_Z, GL_TEXTURE_CUBE_MAP_NEGATIVE_X, GL_TEXTURE_CUBE_MAP_NEGATIVE_Y, GL_TEXTURE_CUBE_MAP_NEGATIVE_Z, or GL_TEXTURE_2D_MULTISAMPLE. For glFramebufferTexture3D, if texture is not zero, then textarget must be GL_TEXTURE_3D. glFramebufferTexture is available only if the GL version is 3.2 or greater. GL_INVALID_ENUM is generated if target is not one of the accepted tokens. GL_INVALID_ENUM is generated if renderbuffertarget is not GL_RENDERBUFFER. GL_INVALID_OPERATION is generated if zero is bound to target. glGenFramebuffers, glBindFramebuffer, glGenRenderbuffers, glFramebufferTexture, glFramebufferTexture1D, glFramebufferTexture2D, glFramebufferTexture3D Copyright 2010 Khronos Group.
