A niche extensible sorting algorithm visualizer.
You are gonna need to download Processing.
Then clone this repo, open algoview.pde and run it!
To add a new algorithm just create a new class that implements the Algorithm interface.
You will get references to an ArrayVisualizer and SqrOsc in the setup() function.
Use the Pointer class to create a new Pointer and give it a color and default index value.
You can use pointers to get, set, and swap values in the array.
The ArrayVisualizer is the main class to help visualize the data on the array and how your algorithm is working with it.
It generates a series of bars which height depends on the array's element value, and paints the pointers on top.
| Method | Returns | Description |
|---|---|---|
void withAlgorithm(Algorithm algorithm) |
Nothing. | Sets algorithm to be visualized. |
int getAtPointer(Pointer pointer) |
Element pointed by pointer. | Gets element pointed by pointer in the visualized array. |
int setAtPointer(Pointer pointer, int value, int offset [optional]) |
Element set at pointer. | Sets element pointed by pointer to value with an optional pointer offset. |
void addPointer(Pointer pointer) |
Nothing. | Adds a pointer to be visualized on the array visualization. |
int getArraySize() |
Visualized array size. | Gets the visualized array size. |
void swapElements(Pointer a, Pointer b) |
Nothing. | Swaps the elements at positions pointed by a and b. |
void stop() |
Nothing. | Tells the visualizer that the algorithm has ended it's execution. You must call this when your algorithm is done. |
To play sounds while your algorithm is running you must use the SqrOsc class instance provided in the setup() function of your Algorithm implementing class.
You can find the SqrOsc documentation on the Processing Sound lib reference.
You will be mostly interested on calling osci.freq(int frequency) so set the tone's frequency depending on the value pointed by a pointer for example.
