I’m trying to change the global light. But all changes I do to the rgb and intensity of the light have no effect :sorrow:
Any ideas? All help much appreciated.
This is part of a larger project so I’ll try to just post the important code. If some more is needed just ask 
The code I’m using (in DrawWorld) for it is
glEnable(GL_LIGHTING);
glShadeModel(GL_SMOOTH);
GLfloat global_ambient[4] = { 0.5f, 0.0f, 1.0f, 0.5f };
glLightModelfv(GL_LIGHT_MODEL_AMBIENT, global_ambient);
My main function is
int main(int argc, char* argv[])
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGBA | GLUT_DEPTH);
glutInitWindowSize(WINDOW_WIDTH, WINDOW_HEIGHT);
glutInitWindowPosition (100, 100);
glutCreateWindow("Car Race");
glutDisplayFunc(HandleDisplayCallback);
glutTimerFunc(SECONDS_PER_FRAME, HandleTimerCallback, GLUT_VISIBLE);
glutReshapeFunc(HandleReshapeCallback);
glutIgnoreKeyRepeat(GL_TRUE);
glutKeyboardFunc(HandleKeyboadKeyDownCallback);
glutKeyboardUpFunc(HandleKeyboadKeyUpCallback);
glutSpecialFunc(HandleKeyboadSpecialKeyDownCallback);
glutSpecialUpFunc(HandleKeyboadSpecialKeyUpCallback);
world = new World();
glutMainLoop();
delete world;
return 0;
}
My HandleDisplayCallback is
void HandleDisplayCallback()
{
ConfigureViewportMain();
DrawWorld();
glutSwapBuffers();
}
And my DrawWorld is
void DrawWorld()
{
glClearColor(0.0f, 0.0f, 0.0f, 0.0f);
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glClearDepth(1.0f);
glEnable(GL_LIGHTING);
glShadeModel(GL_SMOOTH);
GLfloat global_ambient[4] = { 0.5f, 0.0f, 1.0f, 0.5f };
glLightModelfv(GL_LIGHT_MODEL_AMBIENT, global_ambient);
glEnable(GL_DEPTH_TEST);
glDepthFunc(GL_LEQUAL);
glEnable(GL_CULL_FACE);
glCullFace(GL_BACK);
world->Draw();
}
