Is there a method to scale obj by just one dimension?

[kiffa]

I found there is only a Object3D.scale(); Are there some methods like scaleX()\scaleY()\scaleZ()... etc?

No. You can do it by tweaking the rotation matrix directly, but that will also have an influence on an objects normals whichight lead to strange lighting.

what about scaling the object with an IVertexController? will it also suffer from ligting artifacts? unless of course normals are re-calculated.

That should work more or less, because the normals don't scale in that case.
