Hi,
I'm still trying to find the problem with my messed up normals, and I've managed to trace the problem to my vector class.
I'm using the following code to override the minus operator:
SYM_VECTOR SYM_VECTOR::operator -(SYM_VECTOR Vector)
{
SYM_VECTOR Temp;
Temp.i = i - Vector.i;
Temp.k = j - Vector.j;
Temp.j = k - Vector.k;
return Temp;
}
Very simple.
However, the following two expressions give me different results, yet in practice they are exactly the same:
SYM_VECTOR v1, v2, v3, b1, b2;
b1 = v2 - v1;
b2 = v3 - v1;
SYM_VECTOR v1, v2, v3, b1, b2;
b1.i = v2.i - v1.i;
b1.j = v2.j - v1.j;
b1.k = v2.k - v1.k;
b2.i = v3.i - v1.i;
b2.j = v3.j - v1.j;
b2.k = v3.k - v1.k;
Any help appreciated.
