The Visual Representation of a Cartesian 3D Axis System

Click For Summary
SUMMARY

The discussion focuses on the visual representation of a Cartesian 3D axis system, emphasizing the correct orientation of the axes for accurate depiction. The z-axis should be drawn vertically, while the y-axis is positioned anti-clockwise from the x-axis at an angle to create a three-dimensional effect. This arrangement aligns with traditional 2D graphing conventions and ensures that the cross-product (i x j = k) is visually coherent. The perspective is from the positive x and z axes and the negative y axis.

PREREQUISITES
  • Understanding of Cartesian coordinate systems

How do you draw an Cartesian 3D-axis-system?
The Y-axis seems to have some perspective; what's the position of the observer?
What's the 'way' of placement, and why?

All 'links' are welcome.

Hi Valianth! Welcome to PF! :smile:

The convention is that you draw the z-axis up, and the y-axis anti-clockwise from the x-axis … but at an angle, so that it "looks" 3D! :smile:

This is so that it agrees with the usual way of looking at 2D graph paper. And so that the cross-product (i x j = k) looks right!

And you draw it from the perspective of someone in the x and z positive and y negative sector. :smile:

… why were you asking?
