Adding Lighting to a Scene

Click
to show the lighting panel. Or select the
Component Tab
to show all component sub-panels.
To add a light to your scene, click on the desired light and drag it onto your scene. Scaling a light results in the intensity being increased or
decreased. Lights can be re-positioned, re-oriented and animated just like any other
shape.

Point Light The Point Light is
very much like a light bulb. It may be repositioned and animated as with any shape.

Spotlight
The Spotlight behaves exactly like its real
world equivalent. It may be reposition and animated. It also has other attributes such as
its umbra, penumbra and range. These attributes can be set by right-clicking on it and
choosing Properties from the pop-up menu. Umbra and Penumbra are
specified in radians (3.14 = 180 degrees). The range is in model units. |
 |
Area Light
The Area Light is used to illuminate large areas. It is primarily used for creating soft
shadows.

Directional Light
A Directional light is an infinite light source. Its position is infinitely far away, so it is
represented simply as an arrow. This light cannot be moved, but can be re-oriented.
|
In addition to these lights, there is always one Ambient
light within a scene. This light appears as small sphere. It may not be moved. Its
intensity can be scaled in the usual way.
A light's properties can be set by right-clicking on it and choosing Properties from the pop-up menu.
All lights have a color property, which ranges from black (off) to white (maximum
intensity).
Lights that can be moved also have an attenuation factor and method. The attenuation
factor and method specify how the intensity of the light changes with distance. |
