Lines

A line is a straight segment in three-dimensional space defined by its two endpoints, with an optional set of attributes. (In addition, each vertex can have a set of attributes.) A line is defined by the TQ3LineData data type. See "Creating and Editing Lines" for a description of the routines you can use to create and edit lines. Figure 19 shows a line.

typedef struct TQ3LineData {

    TQ3Vertex3D                         vertices[2];

    TQ3AttributeSet                     lineAttributeSet;

} TQ3LineData;

vertices: An array of two vertices.
lineAttributeSet: A set of attributes for the line. The value in this field is NULL if no line attributes are defined.
