The target of the operation, specified by target must be GL_RENDERBUFFER. internalformat specifies the internal format to be used for the renderbuffer object's storage and must be a color-renderable, depth-renderable, or stencil-renderable format, as shown in Table 1 below. width and height are the dimensions, in pixels, of the renderbuffer. Both width and height must be less than or equal to the value of GL_MAX_RENDERBUFFER_SIZE. samples specifies the number of samples to be used for the renderbuffer object's image. If internalformat is a signed or unsigned integer format then samples must be 0. Otherwise, samples must be must be less than or equal to the maximum number of samples supported for internalformat. (see glGetInternalformativ). Upon success, glRenderbufferStorageMultisample deletes any existing data store for the renderbuffer image and the contents of the data store after calling glRenderbufferStorageMultisample are undefined. Since different implementations may support different sample counts for multisample rendering, the actual number of samples allocated for the renderbuffer image is implementation-dependent. However, the resulting value for GL_RENDERBUFFER_SAMPLES is guaranteed to be greater than or equal to samples and no more than the next larger sample count supported by the implementation. GL_INVALID_ENUM is generated if target is not GL_RENDERBUFFER. GL_INVALID_VALUE is generated if samples is greater than the maximum number of samples supported for internalformat. GL_INVALID_ENUM is generated if internalformat is not a color-renderable, depth-renderable, or stencil-renderable format. GL_INVALID_OPERATION is generated if internalformat is a signed or unsigned integer format and samples is greater than 0. GL_INVALID_VALUE is generated if either of width or height is negative, or greater than the value of GL_MAX_RENDERBUFFER_SIZE. GL_OUT_OF_MEMORY is generated if the GL is unable to create a data store of the requested size. glRenderbufferStorageMultisample glGenRenderbuffers, glGetInternalformativ, glBindRenderbuffer, glRenderbufferStorage, glFramebufferRenderbuffer, glDeleteRenderbuffers Copyright 2010-2014 Khronos Group.
