Trouble with Spheres

| Hi
I am currently a university student doing a module that requires me to use
vrml to create a virtual solar system as part of an interface. Dont ask who
sets these tasks :-)
I have created lots of different models of the earth using different texture
maps etc, and they all come out blocky. I have used 3ds Max and created
exactly what i want, but when i export it across to vrml, it does exactly
the same thing.
So my question is, how so i create a perfectly smooth sphere in vrml when
exporting from 3dsmax.
Thankyou in advance
Martin

You problly should define sphere in 3d max with lot of segments, horizontal
and vertical as well, and export it not as primitive shape, 'cause it will
reduce everything you have defined and you will have blocky sphere again.
Only trouble is such mesh can be enormously large vrml file. So it is better
solution to use some program that can create nurbs surface shaped as a
sphere.

Personally I would handle it all by hard coding.....
Define a prototype Planet, with all the basic attributes of a planet.
You may need to extend Planet, for planets that have different features from
your default.
Now simply create instances of your Planet proto.

| some vrml browsers render sphere with more facets than others, i know
that flux has three options in the config., low, medium and high res.,
and high is really quite smooth.
general comment to group;
some time ago i was thinking that it would be very nice if the
primitives had LOD ( level of detail.) built-in, can't see why not,
after all aren't primitives intended to make life simpler?
