color transitions, yo!

Nice, but would be better with PHONG.

Aye, getting advanced, are we? :D The blocks of color are smilebasic limitations, as rgb doesn't support floats (I'm pretty sure).

Yeah... I saw years ago someone using what they called 'phong shading' to smoothly dither along a gradient of only a few colours. It was very impressive. All I can find on google nowadays regarding PHONG is to do with shiny 3D stuff. bah. I guess all I meant was it would be better with dithering :)

I think RGB internally in smileBASIC is something like 5 bits per R,G,B , and then 1 extra bit for transparency. I read that somewhere, I think..

phong is overly complicated if what you want is dithering. Floyd-Steinberg is a better deal. SmileBasic has 32 bit RGBA (or ARGB) so that's the full spectrum.

This function wont be used to make full screen gradients, that was just a demo output. For my purposes this will suffice.

It looks good, Mike. But where's the banding coming from if it's full 32-bit rgba?

The banding is always present, even with full 24 bit colors. That's just how sensitive our eyes are. I have yet to see a gradient demo without color banding.
