When calculating the normal of a vector, which is considered canon:
Returning a copy:
Vector2D Vector2D::Normalize() const {
double a1 = GetX();

Fastest solution to compute normal
A physics engine return a deformed mesh (only geometry vertices).
I take this mesh to render the geometry (~500000 vertices).
What is the fastest solution and the least expensive to compute normal ...
