3D Graph Plotter
3D Graph Plotter
It's been quite a long time since my last blog I agree. I did have to complete my high school after all. However, my non-blog time wasn't wasted. I had been involved during this time developing a few programs for my annual school project. The one that I wish to show here is a 3d Graph Plotter called Visual3D (as I named it). It's purely written in Java and the source is JDK v6 compatible.
3D Graph Plotter in Visualization
Graph Plotters are typically used to create a
visual representation of a mathematical equation. In doing so, the relationship
between the given variables is better understood.
A 3d Graph Plotter is generally concerned with 3
variables – x, y, and z. Where, z is a
function of x & y. In formal terms z = f(x, y). The 3
variables are plotted along the 3 axes in space. The result of such functions
is always a 3d surface varying in height, in the z axis.
The given program can be used to plot any
mathematical function in 3d. The complete set of the functions supported are:
- Trigonometric
- sin()
- cos()
- tan()
- asin()
- acos()
- atan()
- Arithmetic
- sqrt()
- cbrt()
- log()
- ln()
- Miscellanious
- floor()
- ceil()
- abs()
- sign()
Supported constants
- PI
- E
Supported variables
- x
- y
Supported operators
- +
- -
- *
- /
- ^
- %
Program Structure Overview
The program contains a total of 19 classes which are packaged and structured as below:- package visual3d
- class Visual3D (Main Class)
- package core
- class Resource
- package mexparser
- class Constants
- class Expression
- class Lexer
- class Parser
- class Solver
- class Token
- class TokenTable
- package utility
- class Coefficients
- class Edge
- class Face
- class Render3D
- class Vector3D
- package visual
- class Function
- class Model
- class Plotter
- class Screen
- class View
*Update*
I considered adding a few more features for the program.
- Gradient mapping
- Added custom theme support
- View transitions using Numpad(0, 1, 3, 7)
