Opengl Lightning from object

Question

I want to draw some light from an object (sphere in my case, its a pole with a handle and sphere on the top).

The light should draw on the other objects too but from the only sphere as I mentioned.

Currently, I am only getting ambient light only.

I have set the L key to show lightning but it only shows ambient light(darkens the scene) when I press the key.

here is the code

    /// Lights 
    float ambientLight[4] = { 0.35f, 0.35f, 0.35f, 1.0f }; // colour
    float ambientLightOff[4] = { 0.0f, 0.0f, 0.0f, 1.0f }; // colour
    
    float sunLightPos[4] = { 6.f, 15.5f, 5.0f, 0.0f }; // distant above
    float sunLightDif[4] = { 0.8f,0.8f,0.8f,0.8f };
    float sunLightSpec[4] = { 0.8f,0.8f,0.8f,0.8f }; // colour
    float sunLightAmb[4] = { 0.1f,0.1f,0.1f,0.0f }; // colour
    
    
    // materials 
    
    
    float   wooddif1[] = { 0.647059f, 0.164706f, 0.164706f , 1.0f };
    float   woodamb1[] = { 0.41f, 0.164706f, 0.164706f, 1.0f };
    float   woodspe1[] = { 0.547059f, 0.364706f, 0.264706f, 1.0f };

        drawSphere();
        glPopMatrix();
        
        
    }

    {
        if (lighting)
        {
            glEnable(GL_LIGHTING);
            glEnable(GL_NORMALIZE);
            //setShademodel();
        }
        else glDisable(GL_LIGHTING);

        {
        }

Answer 1

A wild guess: the glEnable(GL_LIGHT0) is missing in your code (at least in the posted part).

Just in case, the glLightModeli(GL_LIGHT_MODEL_TWO_SIDE, GL_TRUE); might also be useful to be sure that back-facing triangles are lit.

After that, the GL_SHININESS and GL_SPECULAR parameters should be tweaked to get this kind of highlights.
