A Fast Version of Conway's Game of Life with Thread and DirectX Draw

Introduction

A fast conways's Game of Life Version using MFC,thread and DirectX together with a visual demo for sorting algorithms. It is also a good demo for "Bubble" and "Quick Sort" algorithms.

Conway's Game of Life

For information on Conway's Game of Life, check out the Wikipedia entry: Conway's Game of Life

Backgroud

I built this project just to test the algorithm of Conway's Game of Life,because I found it is very interesting.

Using the Application

Using the Toolbar

  1. Create a document - To create a new MDI view of Conway's Game of Life or Sorting
  2. Open an existing document - To open an existing document of Conway's Game of Life (*.lif) or Sorting (*.sor)
  3. Save a document - To save an MDI frame of Conway's Game of Life (*.lif) or Sorting (*.sor).
  4. Open a document of Conway's Game of Life.
  5. Open a document of Sorting.
  6. Randomly initialize a pattern of the Conway's Game of Life.
  7. Start the calculation on the current active MDI frame.
  8. Stop the calculation.
  9. Clear all cells in the active view and stop the calculation.
  10. A toggle switch to show grid or hide grid.
  11. Slow down - To slow down the creating of further generations of Conway's Game of Life.
  12. Speed up - To speed up the creating of further generations of Conway's Game of Life.
  13. Color Setting - To set the color of cells in Conway's Game of Life or Sorting Bars.

Using the Mouse

  1. Mouse Left Click to add a new cell or remove a cell. It is useful to create an initial pattern manually or to change a stable pattern to be active by adding new neighbour cells,also you can interfere the evolvement by adding or removing neighbour cells with the mouse click. The initial pattern created by the user can be saved and loaded by "Save a document"/"Open a document".
  2. To add/remove cells in a row by moving the mouse cursor with left button down. You can create any initial pattern you want easily.
  3. Right click to "Quick Sort" in Sorting view.

In the Code

To Create an independent thread to implement algorithum of Conways' Game of Life or Sorting

void CSortAndLifeView::CreatSortThread()
{
    unsigned threadID;

    if(hThread)
        CloseHandle(hThread);
    hThread = (HANDLE)_beginthreadex(NULL, 0, thread_proc, this, CREATE_SUSPENDED,
        &threadID);
    ResumeThread(hThread);

}

unsigned int __stdcall CSortAndLifeView::thread_proc(void* pv)
{
    CSortAndLifeView *this_ = reinterpret_cast<CSortAndLifeView*>(pv);
    if(this_->m_bDocumentType == DOCTYPE_LIFE)
        this_->OnLifeGame();
    else if(this_->m_bDocumentType == DOCTYPE_BUBBLESORT)
        this_->OnBubbleSort();
    else if(this_->m_bDocumentType == DOCTYPE_QUICKSORT)
        this_->OnQuickSort();
    _endthreadex( 0 );
    return 0;
}

To override the OnPaint method CFomView Class to implement DirectX drawing

void CSortAndLifeView::OnPaint() 
{
    CPaintDC dc(this);
    OnDraw(&dc);
}

void CSortAndLifeView::OnDraw(CDC* pDC)
{
    // TODO: add draw code for native data here

    CSortAndLifeDoc* pDoc = GetDocument();
    ASSERT_VALID(pDoc);

    GetClientRect(&rectView);

    if(m_bDocumentType == 0)
        m_directXObj.CellDraw((char *)pDoc->m_cCellArray,pDoc->m_cellColor,rectView);
    else
        m_directXObj.BarDraw((int *)pDoc->m_nNumberArray,pDoc->m_barColor,rectView);
    m_directXObj.Display();

}

The cell size of the Conway's Game of Life can be changed by setting the grid number in StdAfx.h

const int CONST_INT_GRIDNUMBER = 50;

Points of Interest

With threads and distributed grid calculation. The application makes a fast Conway's Game of Life.

  • Live Event Date: April 22, 2014 @ 1:00 p.m. ET / 10:00 a.m. PT Database professionals — whether developers or DBAs — can often save valuable time by learning to get the most from their new or existing productivity tools. Whether you're responsible for managing database projects, performing database health checks and reporting, analyzing code, or measuring software engineering metrics, it's likely you're not taking advantage of some of the lesser-known features of Toad from Dell.

  • With JRebel, developers get to see their code changes immediately, fine-tune their code with incremental changes, debug, explore and deploy their code with ease (both locally and remotely), and ultimately spend more time coding instead of waiting for the dreaded application redeploy to finish. Every time a developer tests a code change it takes minutes to build and deploy the application. JRebel keeps the app server running at all times, so testing is instantaneous and interactive.
