Triangles
A triangle is a closed plane figure defined by the three edges that connect three vertices. The entire triangle can have a set of attributes, and any or all of the three vertices can also have a set of attributes. A triangle is defined by the TQ3TriangleData data type. See "Creating and Editing Triangles," beginning on page 4-76 for a description of the routines you can use to create and edit triangles. Figure 4-12 shows a triangle.

typedef struct TQ3TriangleData {
TQ3Vertex3D vertices[3];
TQ3AttributeSet triangleAttributeSet;
} TQ3TriangleData;
Field Description
vertices
- The three vertices that define the three sides of the triangle.
triangleAttributeSet
- A set of attributes for the triangle. The value in this field is
NULL if no triangle attributes are defined.
