Table 6.177 — DRM_Polygon

Property

Description

Class

<DRM Polygon>

Superclass

<DRM Surface Geometry>

Subclass

None.

Definition

An instance of this DRM class specifies a bounded portion of a plane, defined by a set of three or more <DRM Vertex> instances listed in counter-clockwise order. The final segment connecting the last <DRM Vertex> to the first <DRM Vertex> is implicit, not explicit; that is, the first <DRM Vertex> is not duplicated to also appear as the last <DRM Vertex> of the <DRM Polygon>.

Clarifications

¹ This specifies the set of Polygon_Flag tokens applicable to the given <DRM Polygon> instance.

² A <DRM Geometry Face> associated with a <DRM Polygon> instance represents the topology of the specified face (front or back) of that <DRM Polygon>.

³ A <DRM Primitive Geometry> contains a <DRM Union Of Primitive Geometry> instance as a component only when that <DRM Primitive Geometry> can be decomposed into nested <DRM Primitive Geometry>, as (for example) a <DRM Polygon> can be decomposed into subfaces.

Example(s)

One of the surfaces representing the geometry of a vehicle.
