  • <DRM Linear Geometry>

Superclass

Subclass

Definition

An instance of a concrete class derived form this DRM class is a geometric linear representation.

A value of zero (0) for the count field 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. If a <DRM Light Rendering Properties> component is present, then count is the number of evenly spaced light points to be rendered along the <DRM Linear Geometry>. If no <DRM Light Rendering Properties> component is present, then count is the number of evenly spaced line segments to be rendered along the <DRM Linear Geometry>.

If count is greater than zero, the suppress_last field specifies whether the last segment / point in the sequence is suppressed or rendered.

Clarifications

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