### 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)
