Technically yes, given the etomology of the word (many angles).
I would guess the OP has come from LightWave where there is support for
render single point polygons (which are a distinct entity from points) as
pixels. They work quite well for stars.
As far as making stars in XSI what about making a very large sphere set to
emit particles with speed 0 in its volume.
Like this:
CreatePrim "Sphere", "MeshSurface"
CreateParticleCloud "sphere"
SetValue "cloud.cloud.ParticlesOp.sphere_emission.Generation", 3
SetValue "cloud.cloud.ParticlesOp.sphere_emission.Speed", 0
SetValue "cloud.cloud.ParticlesOp.sphere_emission.Rate", 20000
NextFrame
Then set an initial state, or have the rate drop to 0, or export/import
etc.
Then you use one of the particle shaders to get stars, you can even give
them random colors, and random scales, which tend to look very good for
stars.
