Howdy,

I'm trying to translate my C.O.F.F.E.E expression to a C++ plug in, but I'm having a little trouble figuring out the correct syntax in C++ to translate this C.O.F.F.E.E routine:

RotateMatrix(rMatrix,theta)
{
var m = new(Matrix);
m->SetRotY(-theta);

return rMatrix->GetMulM(m);
}

It looks like in C++ MatrixRotY() would replace SetRotY(), but I'm not sure what would replace GetMulM().

Or maybe there is a better way to do the matrix rotation in C++. Any suggestions?

Adios,
Cactus Dan

Hi,

Matrix multiplication is m = m1 * m2;

Howdy,

Thanks Thomas.

So, GetMulM() is just multiplying the two matrices together. I kind of thought so, but when I tried it, I couldn't get it to work. From your reply I realize I was on the right track, but going the wrong way. I was doing m=m2*m1 instead of m=m1*m2. I reckon the order makes a difference, but I'm not sure why (no formal math training, you know).

It's working now. Thanks again.

Adios,
Cactus Dan
