Default spheres looking more like ovals?
Raxx:
cooldude234, there's always my super awesome UVTools scripts :P Anyway, I was addressing the OP issue of non-uniform sphere geometry.
I thought maybe it'd be nice if one could subdivide a cube, adjust it to be perfectly spherical (using my script), and use a cube map for texturing the sphere. I gave it a shot, but there's UV distortion at the edges since the faces aren't all identical in size and shape, and seams :(
ronaldefarmer, can you share that icosphere you posted, but as a .obj so that I can check out its UVs? I might write an icosphere script of my own with unlimited divisions, but only if I can get a logical UV pattern for it. As for the spherize script, I was considering that, and since you're requesting it, I guess I'll make it ;) Expect something posted in the scripts board in the near future.
ronaldefarmer:
Raxx: Here is that icosphere, and also a quadsphere in case you are interested.
About your spherize script, What if the spherize attribute could have a negative value. I used the script to "fatten" a cube (so that the sides were convex) using values less than one, and I am wondering if it might be possible for the attribute to have negative values so that the sides would be concave.
CrashDrive:
I never realized the default sphere had creases at the poles after subdivision.
Been playing around with the Spherize script a bit more.
Started with a cube and subdivided> mesh> Spherize (twice) and got a perfect sphere and no visible creases.
The script really works nice.
cooldude234:
Raxx I really like your Cube mapping method. It looks much better than anim8or's default spherical mapping.
I might look into this some more and make a simple standalone tool in C++ to fix this problem for now at least.
Kyle:
Sounds like a nice script Raxx. I cant seem to get it to work for some reason though. I load the script, even restarted anim8or, select a mesh hit sphereize but see no effect. Tried it after a subdivision as well.
