I’m new to Blender and have just been reading through the pretty good ‘Blender for Dummies’ book. I was wondering if anyone could shed any more light on this following passage:
Faces in Blender are limited to only three-sided and four-sided polygons, often referred to as tris (pronounced like tries) and quads. Other programs have something called an n-gon that can have virtually a limitless number of sides. Blender developers are working on building this feature into Blender and have made great progress. However, at this time, only some development versions of Blender have n-gon functionality. The current release is still limited to tris and quads. This isn’t a completely horrible situation, however. A lot can still be done with just three- and four-sided faces. In fact, most detailed character models are made completely with quads, and all 3D geometry is reduced to triangles when it gets to your computer hardware.
- p. 55
Isn’t only being able to have 4-sided polys constricting? Why do extra sides make all the difference? Why is n-gon functionality so advanced? This book was published in 2009, have there been any changes since then? This book does only seem to refer to pre-Cycles Blender and before the new GUI came in, so I’m gathering there were lots and lots of changes not too long ago.
