Hi
Can someone explain me this source code for lighting in LWJGL? Because now it works but when i rotate camera its lighter or darker. i dont want that. i changed light position but it dont work. its still the same. how i can use that code to emit a sunlights?
// ***********&*******************************LIGHTT***************************************************///
initLightArrays();
glShadeModel(GL_SMOOTH);
glMaterial(GL_FRONT, GL_SPECULAR, matSpecular); // sets specular material color
glMaterialf(GL_FRONT, GL_SHININESS, 50.0f); // sets shininess
glLight(GL_LIGHT0, GL_POSITION, lightPosition); // sets light position
glLight(GL_LIGHT0, GL_SPECULAR, whiteLight); // sets specular light to white
glLight(GL_LIGHT0, GL_DIFFUSE, whiteLight); // sets diffuse light to white
glLightModel(GL_LIGHT_MODEL_AMBIENT, lModelAmbient); // global ambient light
glEnable(GL_LIGHTING); // enables lighting
glEnable(GL_LIGHT0); // enables light0
glEnable(GL_COLOR_MATERIAL); // enables opengl to use glColor3f to define material color
glColorMaterial(GL_FRONT, GL_AMBIENT_AND_DIFFUSE);
