Camera

The Camera tab enables you to adjust the 3D viewing settings for the 3D Effects. By adjusting the parameters for the camera, the user is able to observe the object in a 3D world from different angles or positions over time.


Perspective projection
Determines whether 3D points are projected onto the Layout Panel using perspective rendering. When ticked, you can also specify a starting and ending Zoom Factor. Zoom Factors make no difference, and hence are not enabled, when the 'Perspective Projection' option is turned off.

Start rotation angle
Specifies the angle the camera is rotated around the view vector at the start of the Effect.

End rotation angle
Specifies the angle the camera is rotated around the view vector at the end of the Effect.

Start Zoom factor
Specifies the Zoom Factor of the camera at the start of the Effect. This is only valid for Perspective Projections.

End Zoom factor
Specifies the Zoom Factor of the camera at the end of the Effect. This is only valid for Perspective Projections.

Start position
Specifies the position of the camera at the start of the Effect, where the X axis points left, the Y axis points down, Z axis points to the front, 1 unit is equal to 1 pixel and the origin is at the center of the object.

Middle position
Specifies the position of the camera at the middle of the Effect. The Menu let you select which values you want to change. Any value you don't change uses the value halfway between the corresponding start and end values.

·	Mid-X-Y-Z: midpoint of the camera's motion track = (X, Y, Z)

·	Mid-X-Y: midpoint of the camera's motion track = (X, Y, none)

·	Mid-X-Z: midpoint of the camera's motion track = (X, none, Z)

·	Mid-Y-Z: midpoint of the camera's motion track = (none, Y, Z)

·	Mid-X: midpoint of the camera's motion track = (X, none, none)

·	Mid-Y: midpoint of the camera's motion track = (none, Y, none)

·	Mid-Z: midpoint of the camera's motion track = (none, none, Z)

·	None: camera moves straight from Start Position to End Position

End position
Specifies the position of the camera at the end of the Effect.

Start target
Specifies the point at which the camera is aimed at the start of the Effect.

Middle Position
Specifies the point at which the camera is aimed at the middle of the Effect. The Menu lets you select which values you want to change. Any value you don't change uses the value halfway between the corresponding start and end values.

·	Mid-X-Y-Z: midpoint of the look-at point's motion track = (X, Y, Z)

·	Mid-X-Y: midpoint of the look-at point's motion track = (X, Y, none)

·	Mid-X-Z: midpoint of the look-at point's motion track = (X, none, Z)

·	Mid-Y-Z: midpoint of the look-at point's motion track = (none, Y, Z)

·	Mid-X: midpoint of the look-at point's motion track = (X, none, none)

·	Mid-Y: midpoint of the look-at point's motion track = (none, Y, none)

·	Mid-Z: midpoint of the look-at point's motion track = (none, none, Z)

·	None: the look-at point moves straight from Start target to End target

End target
Specifies the point at which the camera is aimed at the end of the Effect.
