How to visualize a coordinate system?
Oct 13th, 2009, 9:20am  

How do I draw a standart 3-dimensional coordinate system with arrows showing positive directions? I want it toi be present on the screen while drawing some other objects. Is there a simple way or I only coul draw lines separately? how do I draw a vector with arrow on its end, for example?

Thanks in advance, I've tried searching, but to no effect

i usually just draw three lines, no need for arrows

red from 0, 0, 0 to 100, 0, 0
green from 0, 0, 0 to 0, 100, 0
blue from 0, 0, 0 to 0, 0, 100
