Values for floating-point 39e5c31af7Sopenharmony_cioutput values are interpolated from per-vertex data. For integer outputs 40e5c31af7Sopenharmony_cino interpolation is done and flat values are used instead. 41e5c31af7Sopenharmony_ci 42e5c31af7Sopenharmony_ciEach shader output is matched with a framebuffer. For floating-point targets 43e5c31af7Sopenharmony_ciframebuffer can be either default framebuffer, renderbuffer with floating-point 44e5c31af7Sopenharmony_ciformat or normalized fixed point format depending on the test case. For 45e5c31af7Sopenharmony_ciinteger outputs renderbuffer with compatible integer format is always used. 46e5c31af7Sopenharmony_ci 47e5c31af7Sopenharmony_ciResulting image is read from all render targets and compared against 48e5c31af7Sopenharmony_cireference(s) produced by reference rendering code. 49
