Creating polygons

Recommended Posts

When making polygons to fill an area, is it required that they contain either 3 or 4 points? Is it permisible for a polygon to contain many points? For example, for a floor or bulkhead, can the whole thing be a single polygon instead of filling it with rectangles and triangles? My models are getting large. This is for FSDS.Thanks,John Woodward

Yes - a polygon can have as many points as you wish.Caveats. To avoid the dreaded psyho polys (not that you can ever completely avoid them, much to Dwight Booth' chagrin), if your chosen points are non-planar you *could* start getting visual anomalies (hence the term - psycho polys). You want to avoid "bent" polygons.Felix/FFDSPegasus Aviation Design

Additionally, everything gets rendered as triangles in the end anyway...so you're not really saving any performance by using a multi-point poly. Regular rectangles make it easier to see your design and keep it clean...but if the area's already a non-standard shape, you may as well use triangles.Matt

Thanks for the replies. It sounds like for a flat surface like a bulkhead I could select all the points and make one polygon, to save time, but for curved surfaces it might be better to use several polygons. I have been using mostly rectangles where possible but use triangles to connect regions where the number of polygons is different.John Woodward
