openGL character paths

Fi_C**

Hi all

I have a dinosaur character in an open GL scene - and I want to give him a trajectory or path to run around in , it doesn't matter if it is a circle or a line or whatever.
Anyway I have translated him from the origin and want him to rotate around the y axis so I have used
void Dino()
{
glPushMatrix();
glTranslatef( 2.5, 0.0, 0.0);
glRotatef(theta, 0.0, 1.0, 0.0);
drawDino();
glPopMatrix();
}
I am incrementing theta in mt idle function;
void idle(void)
{
theta+= 0.375;
if(theta >=360.0)
{
theta -= 360.0;
}

glutPostRedisplay();
}
but he is only rotating once and then stopping.
Any idea where I am going wrong?
Or better still does anyone know where I can get a tutorial to show me how to do this??
I've tried NeHe but I can't find a suitable tutorial.
Ta,

Hmm that seems fine to me, it must be something in the rest of your code? I know it's a silly question, but have you initialised theta to 0?
Nate Robins has some great tutors that'll give you an idea of how the transformation calls affect the scene.
