    We'll you'll just have to try your best *smartarse*

    I need to know the fastest way to calculate the area of a (random) quadrilateral. Such as any of these. All I know is the (x,y) coords of the 4 corners, they will be screen coordinates and I need to know a decent estimate of the number of pixels in each quad.

    I know one method of calculating an n-sided polygon's area but I was wondering if theree is a fast way especially for quads.

    Preferably no trig if possible.
