smooth curves

A gac plane can have an 8 poly solid of revolution and be very very smooth, smoother than one of mmy 128 poly revolutions. How do they do that? you can see evidence of my blocky curved on my ya-1001.

Try, in gepolyx, using Edit / Round Vertices - it's undoable though so just make a copy of you srf before doing it.

The opposite unfortunately, but if you just split the srf into (what I'm guessing is) the fuselage and the nozzles, you can round just the nozzles for example.

That said, make a copy of the file and just try rounding the whole thing; I've, never really found any bad side effects of doing it.

actually i want to round anything but the nozzles lol
I'll split it
and i have some flat parts that will not be rounded.

I was under the impression gepolyx vertices were rounded by default?

I think if you make vertices in gepolyx they'll be rounded, but I've had things come out of PERL scripts with creases, etc; I'm not entirely sure what constitutes a 'rounded' vertex, but not all programs enforce it apparently, and gepolyx still allows you to export .srf's that aren't rounded. It's a good thing too though, as they can be useful for certain effects, like nozzle petals.

All vertices CREATED in gepolyx are round. However gepolyx displays both round and square vertices identically on screen so you can't tell which is which. Also gepolyX has no function to individually change the round/square status of a vertex, it can only do a "Round All" function that turns all vertices to round. The round/square status of a vertex is retained when you save the model with gepolyx.

If you find "creases" in a model even if you round all the vertices, it can be because there are too many vertices crowded near each other to form a curved surface. Also, if you have a a polygon formed by 4 or more vertices, and these vertices aren't perfectly co-located on the same geometric plane, you may find strange crease like shadows within the polygon.

That is one of the biggest downsides when it comes to using blender. It took me so long to figure out why my models came out so horribly after a paint job.

I use geopolyO, which displays round verices as circles and normal ones as squares. And i found the button to round one vertex at a time =)
