Description

Class

  • <DRM Arc>

Superclass

Subclass

  • None.

Definition

An instance of this DRM class specifies a symmetric curved line, the endpoints of which are specified by the <DRM Vertex> components, such that the curve is symmetric about the <DRM Location> component.

Constraints

Clarifications

1 A value of zero (0) indicates that the given <DRM Linear Geometry> instance is to be rendered as solid.

Otherwise, the interpretation of the count depends on whether a <DRM Light Rendering Properties> component is present for the given <DRM Linear Geometry> instance.

2 If count is greater than zero, this flag indicates whether the last segment / point in the sequence is suppressed or rendered.

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)

  • A geometric representation of a treeline, or a string of lights that follow the path of the <DRM Arc>.
