4 Vertices

A vertex is a dimensionless position in three-dimensional space at which two or more lines (for instance, edges) intersect, with an optional set of vertex attributes. Vertices are defined by the TQ3Vertex3D data type.

typedef struct TQ3Vertex3D {
 TQ3Point3D         point;
 TQ3AttributeSet         attributeSet;
} TQ3Vertex3D;
point A three-dimensional point.
attributeSet A set of attributes for the vertex. The value in this field is NULL if no vertex attributes are defined.
