I want to move my light source in my OpenGL-Scene, which is working. But to actually I want to see thee light source as well.
How can I do this?
...
glPushMatrix();
GLfloat lightPos[] = {0, 0, 200, 1};
glLightfv(GL_LIGHT0, GL_POSITION, lightPos);
GLfloat ambientLight[] = { 0.2, 0.2, 0.2, 1.0};
GLfloat lightColor[] = { 0.5, 0.5, 0.5, 1.0};
glLightModelfv(GL_LIGHT_MODEL_AMBIENT, ambientLight);
glLightfv(GL_LIGHT0, GL_DIFFUSE, lightColor);
glLightfv(GL_LIGHT0, GL_SPECULAR, lightColor);
glutSolidSphere(5,50,50);
glPopMatrix();

A light source is not a visible object, per se. If you want to "see" a light, you have to place some object at the position that your light is. Maybe use a sphere, a sprite, an arrow (pointing in the direction the light is pointing in, if it's a directional light), etc.
