Description:
|
|
|
|
Matrix arithmetic tests operate like other shader rendering tests.
|
|
Input matrices and vectors are read from uniforms, shader inputs
|
|
or constructed as constant values. Operation is performed in shader
|
|
body and the final result is reduced to vec3 that is assigned to
|
|
vertex or fragment color. Rendered image is compared against a
|
|
reference image computed using same algorithm written in C.
|
|
|
|
Matrix constructor and coversion tests compare results against
|
|
pre-computed reference value in fragment shader. Fragment color
|
|
is either white or black depending on whether the result were
|
|
correct or not.
|
|
|
|
Uniform buffer object tests are described in a separate test
|
|
specification document.
