Golf BALL!!

[chips__]

www.suurland.com has a max tut i think....

Ive read through the 3dMax tut on it but i couldnt figure out how to translate it into MAYA.

I dunno how realistic you want but you can do a simple one like this...

1) create a cube
2) smooth it about 3 times
3) in component mode, select all the faces
4) extrude face and scale in slightly
5) extrude face again and translate toward the center
6) smooth again

I wanna consider this a temporary answer. I plan on asking this person (http://trentity.com/images/trentity_slfinal_render.jpg) how they did it for their project.

woohooo Tx Doogie!

for my purposes that technique will do just fine. However i am interested in seeing how someone would go about modeling out a photoreal golf ball. One that would have the same dimple pattern of say a titleist or any of the current golf balls. i still cant believe i never considered smoothing a cube to make a sphere......good thinkin people.


Tx again.

I want to ammend your, Doogie, list just a little bit. I hope you don't mind. :)
1) create a cube (Create a Sub-D sphere)
2) smooth it about 3 times (Convert it to Polygon object and smooth 1 or 2 times)
3) in component mode, select all the faces (Under Polygon>Tool Options>Make sure keep faces together is not checked)
4) extrude face and scale in slightly
5) extrude face again and translate toward the center
6) smooth again (55 thousand polys later you have sort of a golf ball)


Or:

1)Create a Sub-D sphere, because there are no poles on the Sub-D sphere.
2)Convert to Poly and smooth once or twice.
3)Paint a good texture and displacement map (if for close ups).
4)Its easier for animation this way.

Try this texture as a bump/displacement on nurbs sphere with fine tessellation settings.

Good luck

if i just tiled a texture of a single dimple and then projected it into a sphere....how would i correct the distortions at the poles?

[Doogie]

You can't (on a nurbs sphere). The texture above your post has been corrected for the pinching at the poles problem. A subD sphere, however could be textured without this problem.

If you smoothed a cube a few times and map the texture of one dimple on each face (UV map each face for a full texture) would work.

[MasonDoran]

surly there is a way to fix the polar distortion....

[Nicool]

Maybe try a cylindrical mapping instead of an sperical mapping :shrug:

[Doogie]

in NURBs you predistort your texture. For spheres you can mess w/ the convert to polar coordinates plugin (in Photoshop).

I'm not sure what people use for non-sphere pinching, perhaps liquefy? I really don't know how people can texture NURBS (and i haven’t heard a good answer). Look at the map for a Radial head, the whole bottom couple pixels are just for the lips (and your seam runs down the chin). NURBs UVs are there and you can't really change them. I guess people could project textures on them (if so, how do you get the UVs from that??)

[Ken Koala]

This morning I assigned the texture above to the bump channel of a nurbs sphere. It worked fine. I don’t understand why you are having trouble with this. If you have problems with the UV’s use projection maps for you nurb geometry.
Trouble with using polys is that you need a hell of a lot polys to cope with the displacement.
