Camera Information

Use

The Camera information is used to modify settings for the selected camera object.

Following are the elements and their descriptions:

Elements

Functional Description

Perspective

Views the scene in perspective mode. Otherwise, the scene is viewed orthographically.

Zoom Factor

Applies the specified magnification to scene.

Field of View (FOV)

Determines the angle of the field of view (FOV) to best fit a model in the scene. A low value displays a close up of the entire object, and a high value views the object from a greater distance.

FOV Direction Flyout

Used to select the direction with which the FOV angle is applied to the viewport (render target).

  • Minimum from width/height: Calculates and applies the FOV based on either the viewport width or height, whatever dimension is the lesser.

  • Maximum from width/height: Calculates and applies the FOV based on either the viewport width or height, whatever dimension is the greater.

  • Horizontally: Calculates and applies the FOV based on the width of the viewport.

  • Vertically: Calculates and applies the FOV based on the height of the viewport.

Near Clip-Plane

Determines the distance between the camera and the near clipping plane.

Far Clip-Plane

Determines the distance between the camera and the far clipping plane.

Aspect Ratio

This is the relationship between width and height, i.e. aspect ratio = width/height, it is used for ‘output size’ rendering.

Local Coordinates

Used to modify the position of the camera relative to the local origin in the scene.

  • Origin: Displays the coordinates of the origin of the frame of reference in the scene. Usually this is 0,0,0 unless the target point is location under a hierarchy.

  • Target: Displays the coordinates of the target point that the camera is aiming at in the scene.

  • Up point: Displays the coordinates of the camera's 'up point'. That is, the coordinates that forces the camera's view to be straight up. Cameras are defined by three things: an eye (or camera) location, a target location, and an up point. The camera's up point should almost always point straight up. For example, the coordinates 0,0,1 are a straight up point along the Z axis if the Z axis is straight up.
