Breaking a Vector into its 3 Parts

Hi all,

For my Software Engineering class, me and my group decided to do a realistic 3D pool game. Right now I am having trouble trying to figure out how to break a vector into it’s three parts.

I understand the concept of breaking a vector into 2 parts, but I don’t see how I can extend it to the 3D - though the concept is the same.

With 2D you can use because and sin to find the ratio’s of x and why in regards to a unit circle and then multiply it by the magnitude to get the respective x and why magnitudes. I don’t see how you can use this same approach with 3D - as you don’t know how much of the magnitude to give to z axis.

I have tried looking it up online, but all of the tutorials on the subject seem to just cover 2D Vectors…

Any and all help greatly appreciated! Ryan

Answer #1

This is a very specialized question so you might want to ask your tutor for help on this one. Just ask how you go from 2D to 3D using the same concept. Does the rest of your group know? Are there any sources of information in a library? Or on the campus computers?

And to answer your question… I have absolutely no idea.
