Hi Fabrice,
This is my code, I create two spheres to simulates the earth and the
moon, then I lighting these objects with a PointLight3D, but they are
seen with a flat aspect, I would like to have the same effect that I
have with the PointLight3D (the side towards to the sun lighting and
the other side dark), but with smooth objects.
I tried used a PhongBitmapMaterial with DirectionalLight3D or
AmbientLight3D, although i didn´t reached a good result. In fact, the
objects can be seen in a smooth aspect with these lights and
materials, but we cannot see the lighting differences between the two
objects sides.
Thanks.
Tiago.
