Figure 178: Object-Specific, Flat, and Spherical examples
Figure 179: Invert Normals and Double-Sided Illumination examples
• Normals – modifies the rendering style of the 3D surface (Figure 178 and Figure 179).
– Object-Specific – renders the 3D surface according to the shape of the object. For
example, a circular shape is rendered with a spherical surface.
– Flat – renders the 3D surface as polygons.
– Spherical – renders a smooth 3D surface regardless of the shape of the object.
– Invert Normals – inverts or reverses which side of the selected object is considered
to be the outside face and which side is considered the inside face.
– Double-Sided Illumination – lights an object from the outside and the inside of the
object. To use as an ambient light source, click this button, and then click Invert
Normals. This is a setting for the whole of the 3D scene and not fopr a single object
within the scene.
– Double-Sided – a 3D object has a front and back face. With Double-Sided
switched off, only the front face of the object is rendered. The effect, when looking from
outside, is that the object solid, but, when looking from inside, the front face is
