L.4.6.2.3 Light

The complex type, CT_LightRig, defines the lighting of the scene. A light rig consists of a preset direction, preset rig type, and a rotation that serves as an override for the direction. The complex type is defined as:

<xsd:complexType name="CT_LightRig">
  <xsd:sequence>
    <xsd:element name="rot" type="CT_SphereCoords" minOccurs="0"
      maxOccurs="1" />
  </xsd:sequence>
  <xsd:attribute name="rig" type="ST_LightRigType" use="required" />
  <xsd:attribute name="dir" type="ST_LightRigDirection" use="required"/>
</xsd:complexType>

Just as with the camera, the complex type, CT_SphereCoords, is defined elsewhere in the DrawingML. This element, however, serves as an override for the default light right direction. Figure 2 below shows some of the different preset lights applied to a shape.
