Hi Dhiraj,

That depends on your setup. It should work with gl.h. glew and glut both include gl.h

Cheers,

Hey prabhakar,

The syntax is available ALL over the internet, so there is no way I am going to rewrite it

GLdouble eyex,
GLdouble eyey,
GLdouble eyez,
GLdouble centerx,
GLdouble centery,
GLdouble centerz,
GLdouble upx,
GLdouble upy,
GLdouble upz
);

eyex
The position of the eye point.

eyey
The position of the eye point.

eyez
The position of the eye point.

centerx
The position of the reference point.

centery

centerz

A note for those following along on a Linux box. This code will produce an error that looks like:
error: stray ‘\342’ in program
To fix this replace the angled quotes in the program ie: “” with vertical quotes. Just a simple copy and paste thing.
