September 5, 200619 yr In FS9 and possibly in FSX as well, when I see certain objects in VC or outside, the circles seems to be drawn with a certain number of straight lines ( a polygon ). why is that? is there no draw ciricle function or something? If it does, does it use a Polygon with an "n" number of sides and it being limited by the total Polygon count. Is that the issue?Manny Manny Beta tester for SIMStarter
September 5, 200619 yr Yes I believe it is related to polygons and how many there are... the more polygons there are, the rounder the object looks. I don't believe there is a *TRUE* round 3D object.
September 5, 200619 yr Shapes derive from triangles. This is a fundemental characteristic of DirectX and other 3D engines.
September 5, 200619 yr Commercial Member This may also be caused by LODs -- different levels of detail in certain objects. A circular object may really be a 24-sided polygon up close, but to increase performance it might only have 8 sides when far away. You certainly notice 8-sided circles.Visit Godzone Virtual Flight -- for 'Real New Zealand' scenerywww.windowlight.co.nz
