Formula to find distance between 2 3-D points

[TheInsider]

Hi,
Can someone give me a formula to find the distance between any two given 3-D points (x1, y1, z1) and (x2, y2, z2).
Thanks,

Thankyou all for looking at my thread but I think I found the solution already.

You have to use the Pythagorean Theorem to get the distance between two 2D/3D points.

hypotenuse² = adjacent² + opposite²
(a)² = (b)² + (c)²

2D casea = sqrt(b² + c²))
========
dist2D = sqrt((x1 - x2)² + (y1 - y2)²)


3D case: (just add (z1 - z2)²)
========
dist3D = sqrt((x1 - x2)² + (y1 - y2)² + (z1 - z2)²)


Easy, really??
Well, I hope it helps you

Good Luck
