An exemple of code to see 8 level grayscales :

Code: [Select]

:.GRAY8
:[0000000000000000→Pic1
:[FFFFFFFFFFFFFFFF]
:0→A→B→C
:Repeat getKey(15)
:sub(GR)
:DispGraph<sup>r</sup><sup>r</sup>
:End
:Return
:
:Lbl GR
:ClrDraw
:ClrDraw<sup>r</sup>
:1-C→C
:For(Y,0,7)
:For(X,0,11)
:If X+1^2+C
:If 1-A→A
:1-B→B
:End
:End
:Pt-Off(X*8,Y*8,B*8+Pic1)
:Pt-Off(X*8,Y*8,A*8+Pic1)<sup>r</sup>
:End
:EndTop left, there is in order:
black and black, black and gray 75%, gray 75% and gray 25%, gray 75% and white, gray 25% and black, gray 25% and gray 75%, white and gray 25%, white and white.
B change buffer and A back-buffer. C alternates between two screens imaginary.

Actually there is only 7 grayscale (gray 75% and gray 25% = gray 25% and gray 75%).

EDIT : Woa, it work perfectly with full mode.

sick man!

and I think there really is a difference between those tow, just very slight, so yeah it is 8 level

That screenshot looks nice.

Limit is.... 144 grayscales  

EDIT : approximately.

That looks pretty cool.

Chances are if nobody's posting on Cemetech, someone is here and vice versa. That way I can always have someone to discuss programs with.

holy shit...

your gray scale routine in pure axe is the best I've ever seen...

c.sprinkle: I figure the same, though I check cemetech 30% of time and omnimaga 70% of time

An entire evening making head to look for this algorithm instead of revising my courses.

That looks pretty cool.

Heya welcome on Omnimaga! And yeah I agree that both forums got plenty of calculator fans to discuss with plus plenty of varied discussions. I hope you enjoy your stay in the community.

EDIT : approximately.

I really need to try on calc, though. I wonder if it would be practical to use 16 level inside a game in 15 Mhz mode? Sprites might become pretty large in size.

I think I'll dig up my TI-83 Plus Silver Edition and see how it looks like later.

Yeah, probably. The grayscale support for three and four- color is pretty fast, but higher is slowing down by a noticeable amount.
