... is.
Here's some high quality info in this topic on GameDev, including performance issues.
And here's some code to get you started:
float sign (fPoint p1, fPoint p2, fPoint p3)
{
return (p1.x - p3.x) * (p2.y - p3.y) - (p2.x - p3.x) * (p1.y - p3.y);
}
bool PointInTriangle (fPoint pt, fPoint v...

What is tail call optimization?
...ve functions, reuse the stackframe as-is.
The tail-call optimization transforms our recursive code into
unsigned fac_tailrec(unsigned acc, unsigned n)
{
TOP:
if (n < 2) return acc;
acc = n * acc;
n = n - 1;
goto TOP;
}
This can be inlined into fac() and we arrive at
