Operation is performed in shader 49 body and the final result is reduced to vec3 that is assigned to 50 vertex or fragment color. Rendered image is compared against a 51 reference image computed using same algorithm written in C. 52 53 Matrix constructor and coversion tests compare results against 54 pre-computed reference value in fragment shader. Fragment color 55 is either white or black depending on whether the result were 56 correct or not. 57 58 Uniform buffer object tests are described in a separate test 59 specification document. 60
