Maya-03 test 2

+ +

+This test makes some unusual calls to glRotate. For example: +

+
+glRotate(50, 50, 50, 1);
+glRotate(100, 100, 100, 1);
+glRotate(52, 52, 52, 1);
+
+

+These unusual values lead to invalid modelview matrices. +For example, the last glRotate command above produces this matrix with Mesa: +

+1.08536e+24 2.55321e-23 -0.000160389 0 
+5.96937e-25 1.08536e+24 103408 0 
+103408 -0.000160389 1.74755e+09 0 
+0 0 0 nan 
+
+and with NVIDIA's OpenGL: +
+1.4013e-45 0 -nan 0 
+0 1.4013e-45 1.4013e-45 0 
+1.4013e-45 -nan 1.4013e-45 0 
+0 0 0 1.4013e-45 
+
+

+This causes the object in question to be drawn in a strange orientation +and with a semi-random color (between white and black) since GL_FOG is enabled.
