Graph3DC is a 3D graphing App for TI-84 Plus C Silver Edition graphing calculators written entirely in z80 assembly. It integrates with the TI-OS, allowing students and teachers to switch quickly from 2D to 3D graphing mode to graph up to five simultaneous Z=f(X,Y) equations. Users can rotate and zoom functions, control graph colors and styles, set the graphing window, and trace over the mesh to find exact values at points.
