I want to animate a simple object using open GL. I want to move it across the window by changing its x,y and z properties and rotate it. I was thinking about using the method called in glutIdleFunc to change the values of x, y and z coordinates and the angle.. I am using visual studio c++ and i am not having the desired effects on the animation...

i am doing something like:

glfloat teapotPos[3] = {0,0,0};
glfloat teapotAngle = 0;
teapotMaterial[][4]= {{0.2f, 0.3f, 0.5f, 0.8f}, ...., {0.1f, 0.5f, 0.5f, 0.6f}};

void animate(){
/* Change x, y, z and angle of teapot*/
}

void display(){
glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
glMatrixMode( GL_MODELVIEW );
glLoadIdentity( );
glRotated(angle, 0.0, 0.0, 1.0 );
glTranslatef(teapotPos[0], teapotPos[1], teapotPos[2]);
glColor3d(0.7, 0.9, 0.7);
glMaterialfv( GL_FRONT, GL_AMBIENT, teapotMaterial[0] );
glMaterialfv( GL_FRONT, GL_DIFFUSE, teapotMaterial[1]);
glMaterialfv( GL_FRONT, GL_SPECULAR, teapotMaterial[2] );
glMaterialf ( GL_FRONT, GL_SHININESS, 1.5f );
glutSolidTeapot(0.15);
glutSwapBuffers( );
}

int main( int argc, char** argv ) {
glutInit( &argc, argv );
glutInitDisplayMode( GLUT_RGB | GLUT_DEPTH | GLUT_DOUBLE );
glutInitWindowPosition( 50, 50 );
glutInitWindowSize( 512, 512 );
glutCreateWindow( "ANIMATION" );
glutDisplayFunc( display );
glutIdleFunc(animate);
glEnable( GL_DEPTH_TEST );
glutMainLoop( );
return 0;
}

I am using open GL and Visual Studio 2005....

Any comments to the code included or examples / simple tutorials or code examples are welcome...
