Visual Studio OpenGL configuration method

Visual Studio OpenGL configuration method

The files in the OpenGL Development Library include:

Dynamic Link Library file (. dll)

Glu32.dll, Glu. dll, glut. dll, and OpenGL. dll.

Header file (. h)

Gl. H, Glaux. H, glext. H, Glu. H, glut. H, and wglext. h.

Library file (. Lib)

Glaux. Lib, glu32.lib, Glu. Lib, glu32.lib, glut. Lib, opengl32.lib, and OpenGL. Lib.

Configuration method:

1. Copy the. h file in the Development Library to the \ include \ GL directory of Visual C ++ 6.0.

2. Copy the. Lib file to the \ lib directory of Visual C ++ 6.0.

3. Copy the. dll file to the System32 directory of the operating system.
