I'm doing all of this because I have great plans. In fact, I'm developing the functionalities I will need to create new graffiti text effects.
There is a new feature that is almost ready to use. I called it "clean solid wire-frame rendering". It helps to render 3D text that has just the essential lines in the thickness dimension.
It can seem to dummies it's just a trivial simplification, but it's not. It was very hard to develop because the shapes need to be drawn solid and opaque (it goes beyond the technique called "hidden lines removal"). My other solid wire-frame rendering algorithm already was very complicated and strongly based on heuristics. This "clean up" of edges invalidated most of tricks I have used before and needed a lot of other ones. It was almost a total redevelopment involving very hard work.
Below I show this new 3D rendering algorithm in practice. First you see a "normal" 3D wire-frame text and so a "cleaned" 3D wire-frames text created by using my new drawing style.
