+ * The scene is composed of a solid cube whose temperature is unknown. The
+ * emissivity of the cube is 1 and its convection coefficient with the
+ * surrounding fluid is null. At the center of the cube there is a spherical
+ * fluid cavity whose temperature is 350K. The convection coefficient between
+ * the solid and the cavity is 1 and the emissivity of this interface is null.
+ * The ambient radiative temperature of the system is 300K.
+ *
+ * In this test, we compute the radiative temperature that reaches a camera
+ * that looks the cube and we `dump' a normalized image of the result.
