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;

Field Description

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.
