Levotočivá a pravotočivá soustava ve 3D

Karolína Klempířová shared this question 2 years ago

Lze nějak přepnout mezi levotočivým a pravotočivým systémem? Možnost "osa y je svislá" mi příliš nevyhovuje, protože se mi nechce všechno přeznačovat a přepočítávat.

What's the problem with the "y-axis is vertical" option exactly?

Well,for civil ingeneering constructional geometry, we use a left-handed system with vertical z-axis (and positive y-axis going towards you). I need it for my 15-16 year-old students who started with 3D axis concept and Monge projection this year. They need to develop 3D thinking. Of course, I could just switch y and z, but relabeling everything is quite time-consuming.

So "y-axis vertical" then rotate the view as you want?

Well, it would be okay if I used only static images. Relabeling that is okay. I am doing interactive assignments that involve both visual and analytics (for me to know what they have done). Grading the work takes so much more time when I have to switch every y and z.

I just wanted to know if there is an option somewhere in settings I could not find.

Why do you need to relabel? Just rotate the view as you want

But that would still mean that point [5,3,1] would apear on a place the kids are used to see a point [5,1,3], which is kind of a big deal, yeah. I need it to corespond with their textbook view.
