  • <DRM Directional Light Behaviour>

Superclass

Subclass

Definition

An instance of a concrete class derived from this DRM class specifies a directional light having a direction and lobe shape defined by a component <DRM Lobe Data> instance. The lobe shape parameters are used by sub-classes to specify cones, pyramids, blend geometry, and so on.

Directional lights can have both a primary and a secondary colour. These are specified by the <DRM Colour> components of the parent <DRM Geometry Representation> that have colour_mapping values of PRIMARY_LIGHT_RENDERING_BEHAVIOUR and SECONDARY_LIGHT_RENDERING_BEHAVIOUR, respectively.

Clarifications

1 This specifies the lobe shape.
