CGRAPH

A 3D graph for the TI-83 Premium CE calculators. It uses CE C 'Standard' Libraries

This program use the math arbitrary precision for the TI-84+ CE calculators PineappleCAS

This program is a "proof of concept". It was made for fun, and is no longer supported.

Examples

f(x,y) = cos(sin(x*y))

f(x,y) = sqrt( |x*y| )

How to use

• Download CGRAPH.8xp.

• Send it to your calculator using TI Connect CE.

• Put your function f(X,Y) in the Y1 section of the default graph of the calculator.

• Launch the program CGRAPH.

• Choose with the keyboard the precision you want, enjoy.

Issues

• The program don't recognize "forbidden value" it just put 0 at this point.

• Can't move the camera (Not implemented too slow)

Thanks a lot to @nathanfarlow for his help with his library and advises.
