Operation Manual

Figure 182: Example of using Shadow
• Shadow – adds or removes a shadow from a selected 3D object (Figure 182).
– 3D Shadowing On/Off – switches the shadowing on or off.
– Surface angle – enter an angle from 0 to 90 degrees for casting a shadow.
• Camera – sets the camera options for a selected 3D scene as if you are actually using a
camera to take a photograph (Figure 183).
– Distance – enter the distance to leave between the camera and the center of the
selected 3D scene. The default setting for distance is 2.6cm.
– Focal length – enter the focal length of the camera lens, where a small value
corresponds to a fish-eye lens and a large value to a telephoto lens. The default setting
for focal length is 10cm.

3D Effects – Illumination
On the Illumination page of the Effects dialog (Figure 184) you define how a 3D scene is lit and the
settings apply to all 3D objects in a scene. You can specify the direction of the light source for the
3D scene, as well as the color of the light source and of the ambient light.
By default one light source is already selected when you open the Illumination page. However, you
can select another light source or use more than one light source for illumination. A maximum of
eight sources can be used and each light source can use a different color. Figure 184 shows three
light sources selected with each color having a different color. At least one light source must be
active; otherwise, the rendering and shading functions on 3D Effects will not function correctly.
1) Select a Light source icon to turn the required light source on. The icon changes to an
illuminated bulb.
2) Press the space bar or click again on the selected light source so you can adjust the color
and ambient light for the light source.
