The Casio Prizm is a powerful graphing calculator, and led the charge of color-screen calculators. It already has plenty of fun games available, most written by the fair members of our Cemetech community, but educational Add-Ins for the device have been somewhat lacking. Shaun "Merthsoft" McFall's Periodic Table for the Prizm was a great start, and AHelper's gCAS2 brought the Prizm's first semi-symbolic CAS, but few other educational add-ins have been made. I am happy to announce the first full release of Graph3DP, the culmination of six months of sporadic work.
Graph3DP is a powerful 3D graphing application for the Casio Prizm (fx-CG10/fx-CG20). Enter one to six 3D equations, and rotate and zoom the resulting graph. You can adjust the window and trace over the mesh to examine X, Y, and Z value. This final 1.0 release has been thoroughly tested, and the underlying equation-parsing system, AHelper's gCAS2, has been overhauled for speed and correctness. Graph3DP understands thirteen built-in math functions, from sin() to atan() to sqrt() to ln(), plus addition, subtract, multiplication, division, grouping, and exponentiation. Give it a download and try it today; this will surely become an permanent fixture on your Casio Prizm.
