Patch texturing

[snot_nose]

did a nulear bomb fell somewhere or is it that the texturing population is very low?

hopefully the texturing population is very low!!!! (more work oppurtunity for us that way :) )





the best way to texture patch models is with projection maps :)

if its a head, you can use a cylindrical projection map if its like a chest use a planar. The cool thing about projection though is that its based on where you place it.......so you can "project" across multiple patches :)

Patches have implicit texture coordinates. That is one of the reasons many of the big studios still prefer (NURB) patches over subdiviosn surfaces. The whole hassle of getting a sufficient parameterization is eliminated.

Fury:
do u mean just a standard uvw map modifier?
and if you use a cylindrical projection, then how do you work on your texture without the planared wire map??

Mauritius: i think i have midunderstood you. what do you mean by saying:
Patches have implicit texture coordinates

(the stress is on ?implicit?)

one way to do it is to set up a virtual scanner in your software. Basically set up an ortho camera and make it scan 360 around the object you wish to map. Then make an action in photoshop that pieces it together. Its not as difficult as it sounds.......you can find this exact process in a book called Maya 2 Character Animation.

it is a great book even if you arent using maya :)

i think what he meant was explicit, not implicit, unless you did mean that the texture coordinates are merely implied, which i suppose could kinda work with NURBS, since it isnt a true set uv structure as polys are and can be re-built easily.

oh and btw, its always NURBS, cant be NURB, as it stands for Non-Uniform Rational B-Spline........its not a plural......:)

Hope this helps a lil :)

Happy Rendering!!!!

I think i have a lack of information here:
what is a virtual scanner and an ortho camera??? are you sure it's also applied to max? never heard of it.

one of these days im gonna get a chance to scan that tutorial for the world to see.......but im too busy.
