Point Objects

A point object is simply a dimensionless position in three-dimensional space, with an optional set of attributes. A point object is defined by the TQ3PointData data type. See "Creating and Editing Points," beginning on page 4-59 for a description of the routines you can use to create and edit point objects.

typedef struct TQ3PointData {
   TQ3Point3D                 point;
   TQ3AttributeSet            pointAttributeSet;
} TQ3PointData;
Field Description
point
A three-dimensional point.
pointAttributeSet
A set of attributes for the point. The value in this field is NULL if no point attributes are defined.
