Camera Range Structure

You use a camera range structure to get or set the hither and yon clipping planes for a camera. A camera range structure is defined by the TQ3CameraRange data type.

typedef struct TQ3CameraRange {
   float                      hither;
   float                      yon;
} TQ3CameraRange;

Field Description

hither

The distance (measured along the camera vector) from the camera's location to the near clipping plane. The value in this field should always be greater than 0.

yon

The distance (measured along the camera vector) from the camera's location to the far clipping plane. The value in this field should always be greater than the value in the hither field.
