I prefer the first of these two.

The standard convention in mathematics is

y-right, z-up, x-toward yourself

Kind regards

Subject: [MC4D] Notation

Hello,

I’m planning to post a more detailed solution of the physical 2^4 but

to do so I need some notation. I understand that my previous post on

notation was too long and too complicated. Luckily, I have since

realised that a simpler notation is sufficient but before I introduce

it I need some input from you. What coordinate system do you prefer?

It would be great if we could decide on one coordinate system and then

use that as a convention. Personally, I think that the coordinate

system should be right-handed but besides that, I can use pretty much

any. Two great alternatives are (for the positive half axes):

x-right, y-away from yourself, z-up

x-right, y-up, z-toward yourself

What do you think?

Best regards,

Joel
