while I was looking at one of my old programs, I suddenly had an I idea for pure basic 3 level grayscale. by putting dual layer ascii grafix on the graphscreen and one layer on the homescreen, you can switch the screens to see the second layer in grayscale.


however, when testing it on the calc, it seems that the grayscale of every character is a bit darker then the char before is, and thus creating 128 different levels of grayscale.

to bad that the grayscale isn't consistend and that the upper rows are a bit to light to see good, or else this could be used in a game.

here is a program to test it out:

if anyone has any ideas or practical uses for this, please post them.

This is (most likely) because TI's graph screen displaying is so slow. It displays each of the 64 rows from the top to the bottom, slowly (as compared).

I'm fairly sure this is what HarrierFalcon did in the intro for Metroid Pi.

interesting, I'm guessing you didn't try to count the different numbers of gray right ^^ jk

@Darkerline: Love that picture about grays being equal 0x5

@ darkerline, I tried your program, but it somehow crashed my calc (must have been some asm programs I have installed). I didn't try it after that, tho.
