Hasta La Motion!

this is not a Nuke specific problem, but i thought of putting it here as i has the best chance of getting an answer to this here..

well.. my question is how to find the liner distance for one point to another point in 3D

for instance

[X=10, Y=21, Z=23] ——-> [X=13, Y=24, Z=44]

i can figure out the the distance equation for two 2D points

Distance= √(ΔX^2 + ΔY^2)

but can someone hook me up with a equation that results in the distance between two 3D points…. i know this is high school math but im blank on this matter..

thankx again.. :niceone:
