The 3D class formulas for UF are on the back-burner as I'm working on a fractal program (using shader 2) for the Apple "i" devices, roughly modelled on UF but with specifics for 3D+ and other non-UF friendly methods that can be applied in a shader.

Essentially a classic blues-rock, sci-fi, fantasy, programming and fractalling loving geek.
My "day-job" is programming, currently for the iPhone/iPad/iTouch devices.
The rest of the time I mainly spend on fractals - either programming or creating fractal art.
For anyone interested my "studio" is open all year by appointment.
Eventually I hope to make fractals my primary income and the rest of my programming the hobby ;)
Since acquiring a camera at the Gadget Show exhibition in 2011 I have developed (sic) an interest in photography - so far just of the digital kind.....
