Point Light Properties

A Point light comes from a very small light source located at a specific coordinate in the model space. This type of light source emits light in all directions. You can modify the intensity, color, and position of the light source.

To modify properties of a Point light:

1. In the FeatureManager design tree, click to expand Lights, Cameras and Scene .

2. Right-click Point and select Properties.
   The Point PropertyManager appears, and a manipulator appears in the graphics area.

The appearance of the manipulator varies, depending on the zoom scale of the graphics area and the position of the light.

3. In the PropertyManager, set the following options, then click .

Basic

• On/Off . Switches the light off or on in the model.

• Edit Color. Displays the Color palette, so you can select colored light rather than the default white light.

• Ambient . Controls the intensity of the light source. Move the slider or type a value between 0 and 1. A higher value results in more light. The level changes equally on all sides of the model.

• Brightness . Controls the brightness of the light source. Move the slider or type a value between 0 and 1. A higher value results in more light on the side of the model closest to the source.

• Specularity . Controls the extent to which shiny surfaces exhibit bright highlights where the light strikes them. Move the slider or type a value between 0 and 1. A higher value results in more dramatic highlights and a shinier appearance.

Light Position

• Lock to model. When selected, the position of the light relative to the model is maintained. When cleared, the light remains fixed in the model space.

• Coordinate System.

• Spherical. Uses a spherical coordinate system to specify the position of the light source. Drag the manipulator in the graphics area or type values or move the sliders in the PropertyManager for the following:

• Longitude

• Latitude

• Distance

• Cartesian. Uses a Cartesian coordinate system to specify the position of the light source. Drag the manipulator in the graphics area or enter values in the PropertyManager for the following:

• X coordinate

• Y coordinate

• Z coordinate

Move the pointer over the manipulator. When the pointer changes to , you can drag the manipulator.

As you drag the manipulator over the model, the manipulator snaps to various entities such as vertices and edges. The pointer changes to indicate the type of entity being snapped to. To override the snap, press Ctrl while dragging.

Configurations

Applies the lighting adjustments to specific configurations. Select This configuration, All configurations, or Specify configurations.
