Question about scaling
Closed this issue · 2 comments
Hi, I've recently become interested in PGA, and am considering using it in a new Python render engine. Math (especially this kind) is not my strong suit, but the advantages of PGA are compelling .... so I'm trying to wrap this up in a Python lib with an API suited for normal people :)
I'm now a bit stuck and I was hoping you could help. Render engines and 3D modeling tools usually provide 3 kinds of transforms for an object: translations, rotations, and scaling. I understand (more or less) how rotors and translators work, but I have not seen the use of scalors (if that's how you'd call them) anywhere. Is a scaling transform/motor even possible? What about anisotropic scaling?
edit: if there's a better place to ask questions like these, please let me know, and I'll move the question there instead
