Hi,

I know the existence of PosToScreen() and ScreenToPos() methods, but I'm a little confuse about the conversion between 2D and 3D in objects.

Is Vec2 the 2D object of Vec?
If yes, why is there two different results from:
If not, was is it then?

The same thing happens with Edge to Edge2 and Tri to tri2.

Probably I'm doing somthing wrong or I got it all wrong, but I'm really confused in here.

Vec2 is just a 2 dimensional vector for 2 of the components of the 3D vector. PosToScreen results in the 2 dimensional vector of the 3D world position translated/projected to the 2 dimensional display.

Ok, thank you. So Vec(0,0.5,0).v2 = Vec2(0,0.5)

Thanks
