Parameters : r4 = pointer 1 : 0x00 Angle A
0x02 Angle B
0x04 Angle C
r5 = pointer 2 (will hold return values)
Returns : On pointer 2 (r5)

0x02 -Sin(C)*cos(B)*4096
0x04 Sin(B)*4096
0x06 ( [Sin(C)*Cos(A)]-[Cos(C)*Sin(B)*Sin(A)] )*4096
0x08 ( [Cos(C)*Cos(A)]+ [Sin(C)*Sin(B)*Sin(A)] )*4096
0x0a Cos(B)*Sin(A)*4096
0x0c ( [Sin(C)*Sin(A)]+[Cos(C)*Sin(B)*Cos(A)] )*4096
0x0e ( [Cos(C)*Sin(A)]-[Sin(C)*Sin(B)*Cos(A)] )*4096
0x10 Cos(B)*Cos(A)*4096
