Vec normalize()
If possible, can you add a normalize() method to the Vec classes (in addition to the existing normalize method) that returns the normalized vector. This would allow the method to be chained with other operations.

Therefore code like this:

Code:
Vec d = matrix.pos-Cam.matrix.pos; d.normalize();
if(Dot(Cam.matrix.z,d) > 0)
{
}

Could be shortened to this:

Code:
if(Dot(Cam.matrix.z,Vec(matrix.pos-Cam.matrix.pos).normalize()) > 0)
{
}

You can do this:

Code:
if(Dot(Cam.matrix.z, !(matrix.pos-Cam.matrix.pos)) > 0)

thats cool, but one of the main rules for writing easiliy maintainable code is "write stupid code". your example is sure short and sweet, but if someone else came across it - would make person stop and think 'oww whats that??', where suggested example with chained .normalize() is plain and simple, no mysterious symbols and all. so yeah normalize() returning a Vec& would be very fair addition.

RE: Vec normalize()
there can't be a 2nd normalize function with the same name, which differs only in return type
