Graph3CE is a powerful 3D graphing application for the TI-84 Plus CE family. 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 beta release is a port of the Casio Prizm version of this program, utilizing AHelper’s gCAS2 engine. Graph3CE understands thirteen built-in math functions, from sin() to atan() to sqrt() to ln(), plus addition, subtract, multiplication, division, grouping, and exponentiation. Despite being a powerful, color-screen graphing calculator, the TI-84 Plus CE doesn’t come with 3D graphing capabilities: this adds the missing feature. The development of Graph3CE is also documented in a post on my blog.

  • Rendering and rotation of up to six 3D graphs at a 21x21-point grid, or fewer graphs at higher resolution)
  • Tracing over graphs to examine the (X, Y, Z) coordinates of points.
  • User-configurable grid colors, background colors, bounds and axis display, axis labels, and more.
  • User-settable window and zoom.
  • Fast graph computation thanks to built-in CAS.
