Part IV: Materials, Cameras, and Lighting Basics

Camera type and display options
The Type option enables you to change a Free camera to a Target camera and then change back at any time.
The Show Cone option enables you to display the camera’s cone, showing the boundaries of the camera
view when the camera isn’t selected. (The camera cone is always visible when a camera is selected.) The
Show Horizon option sets a horizon line within the camera view, which is a dark gray line where the hori-
zon is located.

Environment ranges and clipping planes
You use the Near and Far Range values to specify the volume within which atmospheric effects like fog and
volume lights are to be contained. The Show option causes these limits to be displayed as yellow rectangles
within the camera’s cone.
You use clipping planes to designate the closest and farthest object that the camera can see. In Max, they are
displayed as red rectangles with crossing diagonals in the camera cone. If the Clip Manually option is dis-
abled, then the clipping planes are set automatically with the Near Clip Plane set to 3 units. Figure 19.5
shows a camera with Clipping Planes specified. The front Clipping Plane intersects the car and chops off its
front end. The far Clipping Plane is far behind the car.
Tip
Clipping planes can be used to create a cutaway view of your model. n
