How to add graphics.h in dev C++

  1. Add header source files into the Dev C++ directory

    • First, download the header files from this Google drive link and extract the files.
    • It contains three files:
      • graphics.h
      • winbgim.h
      • libbgi.a.
    • You need to copy "graphics.h" and "winbgim.h" into include the directory of Dev-Cpp program resource files. The exact directory address is –
      • C:\Program Files (x86)\Dev-Cpp\MinGW64\include
    • Next, copy “libbgi.a” to lib folder, which should be inside MinGW64. The directory address is –
      • C:\Program Files (x86)\Dev-Cpp\MinGW64\lib

  2. Change compiler suit in Dev C++

    • First open Dev C++ appliaction.
    • On the right side of the toolbar, you will have the drop-down menu to select the desired compiler suit.
    • Set it to TDM - GCC 4.9.2 32-bit release.

  3. Configure required linkers for graphics

    • On Dev, C++, look for the Tool option on the top menu.

    • Expand tools and select Compiler Options.

    • You should arrive on the general tab of the compiler options window.

    • Ensure the “Add the following commands when calling the linker” check box is selected.

    • Then add these linkers in the input box – (just copy and paste this line)

      -libgcc -lbgi -lgdi32 -lcomdlg32 -luuid -loleaut32 -lole32

    • Then click on OK to save.

Installation/verification for openGL

OpenGL comes with the X11 installation, to verify, look for the following files:

  • header file: /usr/include/GL/glut.h

  • If OpenGL and/or GLUT is not installed on your system, you can install both with: Ubuntu: sudo apt-get install freeglut3-dev

    or

    Fedora/RedHat: sudo yum install freeglut-devel

    which should install all the dependent packages, including OpenGL itself. You must have sudo/administrator privileges.

  • In your OpenGL source files, include the following line:

    #include <GL/glut.h>

You don't need to include gl.h and glu.h, as they are already included in glut.h.

  • To make a GLUT application on the command line, use the following linker options:

    -lGL -lGLU -lglut

Programs

  1. Scan Conversion Algorithm

    The process of representing continuous graphics object as a collection of discrete pixels is known as scan conversion.

  2. 2D Geometric Transformations

  3. 3D Geometric transformation

  4. 3D Objects Representation

  5. Visible Surface Detection

  6. Introduction to OpenGL

    copy the files and make new project for dev for openGL programming
