Problem with Perspective

Hi I have problem with setting up perspective. Although, I use the following func. seems like I am getting glOrtho with dimensions x, y and z from -1.0f to 1.0f Any idea?

void DRAW :: SetUP_Environment (int w, int h){
glEnable( GL_DEPTH_TEST );
glViewport(0, 0, w, h);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
gluPerspective(10.0f,(GLfloat)w/(GLfloat)h, 0.1f, 1000.0f);
glMatrixMode(GL_MODELVIEW);
gluLookAt( Cam_X, Cam_Y, Cam_Z, 0, 0, 0, 0, 1, 0 );
}

void gluPerspective(
GLdouble fovy, //try 90deg not 10
GLdouble aspect,
GLdouble zNear,
GLdouble zFar
);

Parameters
fovy
The field of view angle, in degrees, in the y-direction.
aspect
The aspect ratio that determines the field of view in the x-direction. The aspect ratio is the ratio of x (width) to y (height).
zNear
The distance from the viewer to the near clipping plane (always positive).
zFar
The distance from the viewer to the far clipping plane (always positive).

Thanks now it is working.
