Camera

The complex type, CT_Camera, defines a camera within the 3-D scene. A camera is based on a preset, with an optional rotation, field-of-view, and zoom, which all act as overrides for the preset values. A camera is defined in the following way:

<xsd:complexType name="CT_Camera">
  <xsd:sequence>
    <xsd:element name="rot" type="CT_SphereCoords" minOccurs="0" 
      maxOccurs="1" oxsd:dataStructure="optional" />
  </xsd:sequence>
  <xsd:attribute name="prst" type="ST_PresetCameraType" use="required"
    />
  <xsd:attribute name="fov" type="ST_FOVAngle" use="optional" />
  <xsd:attribute name="zoom" type="ST_PositivePercentage"
    use="optional" default="100000" />
</xsd:complexType>

The only complex type contained in the camera, CT_SphereCoords, is a type defined elsewhere within the DrawingML. There are three simple types associated with a camera:

• ST_FOVAngle (field of view angle), which is a positive angle between 0 and 180 in 60,000th of a degree.

• ST_PositivePercentage (zoom), which is defined as a percentage in 1,000th of a percent.

• ST_PresentCameraType (preset camera)

Figure 1 below shows some different presets applied to a shape.
