[ISO/IEC 29500-1 1st Edition]

20.1.5.5 camera (Camera)

This element defines the placement and properties of the camera in the 3D scene. The camera position and properties modify the view of the scene.

[Example: Consider the following example of a camera in DrawingML:

<a:camera prst="orthographicFront">
<a:rot lat="19902513" lon="17826689" rev="1362739"/>
</a:camera>

In this example, we see a preset camera being defined along with a rotation containing latitude, longitude, and revolution overrides provided that further rotate the camera around the scene. The effect of this camera can be seen on the following shape:

end example]

Child Elements	Subclause

Attributes	Description
fov (Field of View)	Provides an override for the default field of view for the camera. Different perspectives can be obtained by modifying this attribute. [Example: Consider the following example of a fov in DrawingML: <a:camera prst="perspectiveContrastingRightFacing" fov="6900000"> <a:rot lat="1200000" lon="18000000" rev="1200000"/> </a:camera> In this example, we see a fov being defined which modifies the default fov for the preset camera. end example] The possible values for this attribute are defined by the ST_FOVAngle simple type (§20.1.10.26).
prst (Preset Camera Type)	Defines the preset camera that is being used by the camera element. The preset camera defines a starting point for common preset rotations in space. [Example: Consider the following example of a prst in DrawingML: <a:camera prst="perspectiveContrastingRightFacing" fov="6900000"> <a:rot lat="1200000" lon="18000000" rev="1200000"/> </a:camera> In this example, we see a prst being defined as perspectiveContrastingRightFacing. end example] The possible values for this attribute are defined by the ST_PresetCameraType simple type (§20.1.10.47).
zoom (Zoom)	Defines the zoom factor of a given camera element. The zoom modifies the scene as a whole and zooms in or out accordingly. [Example: Consider the following example of a zoom in DrawingML: <a:camera prst="perspectiveContrastingRightFacing" fov="6900000" zoom="200000"> <a:rot lat="1200000" lon="18000000" rev="1200000"/> /a:camera> In this example, we see a zoom being used which zooms the scene by 200%. end example] The possible values for this attribute are defined by the ST_PositivePercentage simple type (§20.1.10.46).
