I am in the process of writing a Finite Element Post Processor for an app I am developing.
The pic below shows the current state of play
Soooooo, here is what I need to do next.
Basically I want to turn this into a 3D model (its 2D at the mo)
So I need to ‘revolve - extrude’ the mesh about the left hand vertical axis. Simple enough but I am being lazy.
To clarify a little… If I copied the above mesh and created 18 revolved copies at 10degrees I would have a ‘fan-like’ 3D ish, structure. The only thing missing is the ‘joining’ lines of the outer surfaces. This is crude, obviously, because you don’t need the internal fan but my OGL code should take care of the internal face removal.
My question… Is there a way to ‘revolve’ the 2D group about an axis so that the external surfaces are automatically created?
I am thinking, kind of the same way you can create a triangle strip or fan … am I making sense?
I can produce the external polygons myself but it will take a day or two of coding (I will have to work out which lines are external). I was just wondering if there was something simpler to try. “Oh you need the — GL-Magic2Dto3D command” etc
Sorry if this doesn’t make sense…
Thanks for any input
