We need a C/C++ compiler, either GCC (GNU Compiler Collection) from MinGW or Cygwin (for Windows), or Visual C/C++ Compiler, or others.
Download opengl driver for mac for free. System Tools downloads - opengl by Apple Inc. And many more programs are available for instant and free download. This chapter provides an overview of OpenGL and the interfaces your application uses on the Mac platform to tap into it. OpenGL Concepts. To understand how OpenGL fits into OS X and your application, you should first understand how OpenGL is designed. OpenGL Implements a Client-Server Model. OpenGL uses a client-server model, as shown in Figure.
We need the following sets of libraries in programming OpenGL:
gl
' (e.g., glColor
, glVertex
, glTranslate
, glRotate
). The Core OpenGL models an object via a set of geometric primitives, such as point, line, and polygon.glu
' (e.g., gluLookAt
, gluPerspective
)glut
' (e.g., glutCreatewindow
, glutMouseFunc
). Each of the software package consists of:
gl.h
' for core OpenGL, 'glu.h
' for GLU, and 'glut.h
' (or 'freeglut.h
') for GLUT, typically kept under 'includeGL
' directory.libopengl32.a
' for core OpenGL, 'libglu32.a
' for GLU, 'libglut32.a
' (or 'libfreeglut.a
' or 'glut32.lib
') for GLUT, typically kept under 'lib
' directory.glut32.dll
' (for 'freeglut.dll
') for GLUT under Win32, typically kept under 'bin
' or 'c:windowssystem32
'.It is important to locate the directory path and the actual filename of these header files and libraries in your operating platform in order to properly setup the OpenGL programming environment.

We could use either MinGW or Cygwin.

We will do this later.

On command-line (for GCC), we could use option -I<dir>
for include-path, -L<dir>
for lib-path, and -l<lib>
for library.

The most important option is -l<lib>
, which specifies the 'library' to be linked. You might also need -I<dir>
to specify the 'include-path' and -L<dir>
to specify the 'lib-path', if the header files and libraries are not kept in implicit directories used by the compiler.
You can find the commands used in Eclipse CDT for build the project at '.metadata.pluginsorg.eclipse.cdt.uiglobal-build.log

': Try remove '#include <gl/glaux.h>
' from the source code. (Nehe's tutorial codes included a header 'glglaux.h
' for reading BMP file from Lesson #6 onwards. Lesson #1 to #5 do not require this header. GLUAX is obsolete and excluded from Windows SDK v6.0a.) If that does not work, you may have to download and install GLUAX package.You can use the following command-line options to compile and link an OpenGL program. (You should study the command-line options produced by VC++. Right-click on the project name ⇒ Properties ⇒ Expand 'Configuration Properties' node ⇒ Expand 'C/C++' or 'Linker' sub-node ⇒ Command-line.) Assume that the headers (gl.h
, glu.h
, glut.h
) path is set in the INCLUDE
environment variable, and the link libraries (opengl32.lib
, glu32.lib
, glut32.lib
) path is set in the LIB
environment variable:
Nehe's production maintains an excellent OpenGL tutorial @ http://nehe.gamedev.net.
OpenGL is language neutral, i.e., you can write your OpenGL programs in Windows, Java, Linux, Mac, etc. Under Windows, there are again many ways to write a OpenGL program. e.g., Win32 API directly, GLUT or FreeGLUT, SDL (Single DirectMedia Layer), Allegro, etc.
Nehe's lessons are explained in Win32 API, which is complex, cumbersome and hard and to understand. Nonetheless, the solutions are also ported to all the other platforms. I strongly suggest that you follow the solution using GLUT (which greatly simplifies interaction to Windows).
Link to OpenGL/Computer Graphics References and ResourcesThe Khronos Group announces the release of the Vulkan 1.2 specification for GPU acceleration. This release integrates 23 proven extensions into the core Vulkan API, bringing significant developer-requested access to new hardware functionality, improved application performance, and enhanced API usability. Multiple GPU vendors have certified conformant implementations, and significant open source tooling is expected during January 2020. Vulkan continues to evolve by listening to developer needs, shipping new functionality as extensions, and then consolidating extensions that receive positive developer feedback into a unified core API specification. Khronos and the Vulkan community will support Vulkan 1.2 in a wide range of open source compilers, tools, and debuggers by the end of January 2020. Driver release updates will be posted on the Vulkan Public Release Tracker.
