Figure 165: The favorites (from left to right): Metal,
Gold, Chrome, Plastic and Wood
With the individual color parameters, additional effects can be produced. The
meaning of these parameters corresponds to those on the Illumination dialog page.
Materials and textures can be combined with one another. Settings only simulate
materials and it is sometimes a matter of trial and error to achieve the desired result.
Tip
Do not use too high a brightness value for individual colors. These are
all additive and it is easy to end up with a totally white “colored” area.
The Illumination color brightens those
parts of the object which lie in shadow
making the body seem more illuminated.
When textures are used as well, the
Illumination color is combined with the
white color part of the texture. On the left
the object has a black Illumination color, on
the right bright green.
The Specular color simulates the reflecting
capacity of the surface. The position of the
illuminated point is determined by the
setting of the first light source.
Left: Set the Specular color the same as
the object color and the illumination point
intensity to a low value, in order to give the
impression of a matt body.
Right: Set the Illumination point color the
same as the light source color, in order to
give a shiny appearance to the object
surface.
Metallic surfaces and glass are not so well simulated, because the impression of
these materials is produced through reflection. Such simulation cannot (at the
moment) be calculated by OpenOffice.org.
3D settings for 3D shapes
3D shapes are handled quite differently from objects in 3D scenes. The appearance of
a shape object is changed using the 3D-Settings toolbar (see Figure 166). The 3D
Effects dialog described above should not be used for shape objects as it will not give
the correct formatting results.
