Summary

Description

left-handed coordinate system

Image set Handedness of coordinate systems; RGB Povray
3D coordinate systems can have two different orientations. The circular arrows indicate positive rotation.

This image was created with POV-Ray. Category:Created with Persistence of Vision#Left-handed%20coordinate%20system%20(z%20to%20back).png

This is the default coordinate system in the raytracing program POV-Ray, which was used to create this file.
Cinema 4D also uses a left-hand coordinate system, and the axes have these colors.
