Maya 2020 fundamentals - modelling the real world
Get halfway through a model and find it's an unworkable mess? Can't add edge loops where you need them? Can't subdivide a mesh properly? If any of this sounds familiar check this course out.

New here...new question (?)

hello there, i'm new here. i have a question, don't know if it has already been asked, but anyway:
can someone explain to me the difference between the modeling choices there are (nurbs, poly's, sub-d's)
and the pros and cons for these choices when modeling a character.....
thnx in advance!

in nurbs u use a lot of curves, it's more smooth than polygon. but poly is easyer for low poly models (less detail, eg: in games). subdiv combines the 2, smoothness of nurbs, but you handle it more like polygonal.

someone correct me if i'm wrong about something though.

Nurbs - composed of curves, which, mathmaticly, can only be composed of up to 4 sides, thus are a bit limited when it comes to complicated objects unless you patch model. As they are made up of curves, they are very smooth.

Polygons - composed of points with surfaces spaned between them, they are mathmaticaly only composed of coordinates, so you can have as many sides as you want with a polygonal object, so they are pretty free to make whatever you want. As they are composed of coordinates, they are not as smooth as nurbs, so in order to get a smooth surface, you have to have a lot of geometry.

SubDs - I don't know as much about SubDs because I rarely use them. I'm not sure how they work mathmatically. I do know that what you pretty much get is the smoothness of nurbs, with the freedom of polygons, much like d24e said. They are very taxing on computers, though. My system can't handle them very well, which is why I don't mess with them.
