The safe viewable volume of the frustum, and the zero parallax plane area appear and are denoted with
a transparent colour. The aiming target is centered at zero parallax.
8 Change the position of the near and far clipping planes to alter the depth of the frustum. See Moving
the Near and Far Clipping Planes
(page 640).
9 Change the position of the camera to alter the orientation of the frustum. See
Moving the 3D Camera
(page 640).
10 Change the position of the camera's aim to alter the orientation of the frustum. See Adjusting the Aim
of the 3D Camera
(page 640).
11 Adjust the angle of view to adjust the size of the objects as viewed by the camera. See
Adjusting the
Field of View
(page 641).
Near and Far Clipping Planes
The camera frustum is determined by six clipping planes: the left, right, top, bottom, near, and far clipping
planes. The depth of the frustum is affected by the near and far. The values for these channels are expressed
in pixels relative to the position of the camera.
Set the Near and Far clipping planes to the lowest and highest respective values that produce the desired
result. If the distance between the near and far clipping planes is much larger than is required to contain
all the objects in the scene, the image quality of some objects may be poor.
TIP Objects that you want to render are usually within a certain range from the camera. Setting the near and far
clipping planes just slightly beyond the limits of the objects in the scene can help improve image quality.
The ratio of far:near clipping planes determines the depth precision. Try to keep that ratio as small as possible
for better results. Since most of the depth precision is concentrated around the near clip plane, try to avoid
a lot of detail on distant objects.
