glFramebufferTexture: man3/glFramebufferTexture.xml
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_ATTACHMENT, GL_DEPTH_ATTACHMENT, GL_STENCIL_ATTACHMENT or GL_DEPTH_STENCIL_ATTACHMENT. in GL_COLOR_ATTACHMENT 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 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_X GL_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 log<sub> 2</sub> 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 log<sub> 2</sub> 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 log<sub> 2</sub> 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.
