:For(A,0,20)
:A*B->C
:End

Can be changed to:

Code: [Select]

:-B->A
:For(D,0,20)
:A+B->A->C
:End

And now you've removed a multiplication. If you add rotation, you have to do 2 additions: one for the Y spacing and one for the X spacing.

@Quigibo: I don't fully understand the concept behind what you are doing. Can you explain it?

that isn't in the code you linked to.

thanks, but to make sure I'm understanding correctly, could someone make a pic like calc84maniac's and label the d1, d2, r1, and r2?
I'm still a bit confused... I just can't picture things in 3D.

do what i did.
Take quigibo's mode 7 code.
in your program only draw to L3.
put in quigibo's code right where you would normally have display gragh.
note: change all Y's in quigibo's code to (20-y). (maybe 30-y i can't remember and don't have my calc near me.)

Then you can fiddle around with his code to understand it.
