Are there any situations where using a polygon soup is more advantageous than the other formats?

@marshmallow Yes! When you want to send geometry down the rasterization pipeline. ;-)

Why does polygon soup result in spaces between the triangles, don't we still have the exact coordinates of where all the triangles should be?

Can we use something like triangle strip in OpenGL to reduce the redundancy?

@triangle There are gaps in the picture just to illustrate the idea that the triangles in the list aren't "connected" by any explicit connectivity information. The image on the top right is a more realistic picture of what polygon soup (might) actually look like when encountered in practice---you can't tell it's soup! (Until you try to do something with it, and realize there's no useful connectivity...)
