3D Effects: Geometry
By using this feature, the user can control the
manner and quality of how the object surface is
geometrically calculated and displayed. For
example, interesting effects can be produced by
deliberately reducing the number of segments of
a sphere. Properties of the 3D font, such as the
slant of the edge (bevel), depth, et cetera are
determined here.
3D Effects: Shading
This feature permits specifying the setting
of the shader (flat, phong or
Gouraud) to be used to display the 3D
object. Gouraud provides the best
shading, but requires the most computing
time. Also use this feature to specify a
shadow for the 3D object and to select the
camera distance and focal length.
