Hi,

what is like the best way to change the position of the light source(s)?

I'm using either

F3DN.Navigator3D.Lights[0].Position.Translate(vec4f);

or

Code: Select all

F3DN.Navigator3D.Lights[0].Translate(80, 80, 80);

but nothing seems to happen. Not even when I change those values for all light sources.
Whereas changing the color of the light works perferctly fine with the following line

Code: Select all

diffColor.SetColor(0, 0, 120);
F3DN.Navigator3D.Light[0].Diffuse := diffcolor

Any ideas why?

Hello Mike,

The position of the light source(s) isn't changed because it is set each time when the F3DN.Navigator3D.GLDCScene.Position.OnNotifyChange event fires. You may try to suppress this behaviour by using some custom OnNotifyChange event handler.
