[vtkusers] A Light Emiting Object

[Naim]

Hi, I used this function to eliminate shading

void CGLModelViewCtrl::RemoveShading()
{
	// eliminate shading
	m_prenderer->LightFollowCameraOn();
	m_prenderer->TwoSidedLightingOn();
	m_prenderer->GetTwoSidedLighting();

	vtkLight *light1 = vtkLight::New();
		light1->SetLightTypeToCameraLight();

		light1->PositionalOn();
		light1->SetConeAngle(180);
		light1->SetIntensity(0.5);
		light1->SetPosition(1,0,1);

    vtkLight *light2 = vtkLight::New();
		light2->SetLightTypeToCameraLight();
		light2->PositionalOn();
		light2->SetConeAngle(180);
		light2->SetIntensity(0.5);
		light2->SetPosition(0,1,1);

    vtkLight *light3 = vtkLight::New();
		light3->SetLightTypeToCameraLight();
		light3->PositionalOn();
		light3->SetConeAngle(180);
		light3->SetIntensity(0.5);
		light3->SetPosition(-1,0,1);

    vtkLight *light4 = vtkLight::New();
		light4->SetLightTypeToCameraLight();
		light4->PositionalOn();
		light4->SetConeAngle(180);
		light4->SetIntensity(0.5);
		light4->SetPosition(0,-1,1);
   	
    m_prenderer->AddLight(light1);
    m_prenderer->AddLight(light2);
    m_prenderer->AddLight(light3);
    m_prenderer->AddLight(light4);
	
	// release memory
	int objectCount = 4; // number of objects to delete
	CleanUpObjects(objectCount, light1, light2, light3, light4);
}

Hello! I'm new to VTK and I have a question: is it
possible to make an object to emit light in all
diretions, like the sun? I'm trying to create a solar
system model (I'm a colledge student), and the
examples I've looked didn't have something that I
could use to implement this. 
If it is not possible, then there is someway to
"simulate" the sunlight? It has to be light spreading
in all directions.
Thanks for any ideas!
