I have an Art degree, no math involved, so sometimes when doing 3D graphics and envisioning problems, it's hard to search for solutions over the internet since I don't have good pointers for search terms.
I'm sure this is a trivial problem with a proper name/solution. Basically I just want to grab P and scale its position vector so it matches P', a position on a version scaled by 0.5 on the y axis.
My idea is to apply the same rationale to all three axis, even though I only need to do it on 2, right now.
Thanks in advance.
