Hello everyone,
I am working on a rudimentary 3D rendering system. I was wondering if it is viable/efficient to render all the polies with the GeneralPath method of creating polygons, and then filling it in. I am aware that this would make it difficult to use textures, but as it stands I only want cell-shading. Is this possible? Thanks for any help.

I would be very, very surprised if the garbage collection overhead of creating and destroying thousands of GeneralPath objects every second wouldn't kill performance.

Why are you writing your own renderer? If it's for your own education purposes then you're best off doing everything, including rasterisation, yourself.
If it's for use in some other project, then you a million times better off just going to opengl or using someone else's software renderer.

It's not that bad - depends how many polys you need. z4rch kinda hits the limits of Graphics.fillPoly().
