Abstract

• Project Areas 3D Graphics, Modular design
• Purpose to create a program that graphs
  multivariable functions
• Allows user to rotate graphs
• Also includes matrix editor operations
• Might enable list editor operations

3
Introduction

• Will be put on student Intranet, so it requires
  modular design
• Matrices used for rotations stretches
• Acos(a) -sin(a)
• sin(a) cos(a)
• Matrix above rotates graphs by an angle a

4
Introduction

• Current programs in this area
• Maple
• MatLab
• Mathematica
• Other programs built-in to calculators

5
Development Construction

• Module for matrix editing
• Separate window used to input data into matrix
• Data read in when matrix editor closed
• Binary expression tree-like class used to store
  matrix operations
• No set order of operations

6
Development Construction

• Java used for GUIs
• Main problem getting modules to interact
  properly
• Panels tended to not go away when another panel
  placed on top
• Currently working on matrix operations
  (inversion, row reduction, etc.)

7
Results and Conclusions

• More recursive algorithms used
• More classes added
• Found example program for graphing multivariable
  functions
