GLFRAMEBUFFERRENDERB(3G) OpenGL 3.3 GLFRAMEBUFFERRENDERB(3G) NAME
glFramebufferRenderbuffer - attach a renderbuffer as a logical buffer to the currently bound framebuffer object C SPECIFICATION
GLsync glFramebufferRenderbuffer(GLenum target, GLenum attachment, GLenum renderbuffertarget, GLuint renderbuffer); PARAMETERS
target Specifies the framebuffer target. target must be GL_DRAW_FRAMEBUFFER, GL_READ_FRAMEBUFFER, or GL_FRAMEBUFFER. GL_FRAMEBUFFER is equivalent to GL_DRAW_FRAMEBUFFER. attachment Specifies the attachment point of the framebuffer. renderbuffertarget Specifies the renderbuffer target and must be GL_RENDERBUFFER. renderbuffer Specifies the name of an existing renderbuffer object of type renderbuffertarget to attach. DESCRIPTION
glFramebufferRenderbuffer attaches a renderbuffer as one of the logical buffers of the currently bound framebuffer object. renderbuffer is the name of the renderbuffer object to attach and must be either zero, or the name of an existing renderbuffer object of type renderbuffertarget. If renderbuffer is not zero and if glFramebufferRenderbuffer is successful, then the renderbuffer name renderbuffer will be used as the logical buffer identified by attachment of the framebuffer currently bound to target. 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. All other state values of the attachment point specified by attachment are set to their default values. No change is made to the state of the renderbuuffer object and any previous attachment to the attachment logical buffer of the framebuffer target is broken. Calling glFramebufferRenderbuffer with the renderbuffer name zero will detach the image, if any, identified by attachment, in the framebuffer currently bound to target. All state values of the attachment point specified by attachment in the object bound to target are set to their default values. Setting attachment to the value GL_DEPTH_STENCIL_ATTACHMENT is a special case causing both the depth and stencil attachments of the framebuffer object to be set to renderbuffer, which should have the base internal format GL_DEPTH_STENCIL. ERRORS
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. SEE ALSO

GLFRAMEBUFFERTEXTURE(3G) OpenGL Manual GLFRAMEBUFFERTEXTURE(3G) NAME
glFramebufferTexture - attach a level of a texture object as a logical buffer to the currently bound framebuffer object C SPECIFICATION
void glFramebufferTexture(GLenum target, GLenum attachment, GLuint texture, GLint level); void glFramebufferTexture1D(GLenum target, GLenum attachment, GLenum textarget, GLuint texture, GLint level); void glFramebufferTexture2D(GLenum target, GLenum attachment, GLenum textarget, GLuint texture, GLint level); void glFramebufferTexture3D(GLenum target, GLenum attachment, GLenum textarget, GLuint texture, GLint level, GLint layer); PARAMETERS
target Specifies the framebuffer target. target must be GL_DRAW_FRAMEBUFFER, GL_READ_FRAMEBUFFER, or GL_FRAMEBUFFER. 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. textarget For glFramebufferTexture1D, glFramebufferTexture2D and glFramebufferTexture3D, specifies what type of texture is expected in the texture parameter, or for cube map textures, which face is to be attached. texture Specifies the texture object to attach to the framebuffer attachment point named by attachment. level Specifies the mipmap level of texture to attach. DESCRIPTION
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_ATTACHMENTand the GL_STENCIL_ATTACHMENT attachment points simultaneously. textarget specifies what type of texture is named by texture, and for cube map textures, specifies the face that is to be attached. If texture is not zero, it must be the name of an existing texture with type textarget, unless it is a cube map texture, in which case textarget must be GL_TEXTURE_CUBE_MAP_POSITIVE_XGL_TEXTURE_CUBE_MAP_NEGATIVE_X, GL_TEXTURE_CUBE_MAP_POSITIVE_Y, GL_TEXTURE_CUBE_MAP_NEGATIVE_Y, GL_TEXTURE_CUBE_MAP_POSITIVE_Z, or GL_TEXTURE_CUBE_MAP_NEGATIVE_Z. 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. NOTES
glFramebufferTexture is available only if the GL version is 3.2 or greater. ERRORS
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. GL_INVALID_OPERATION is generated if textarget and texture are not compatible. SEE ALSO
