Class Name: LSR 3D Location Control Link

Superclass - <Control Link>

Subclasses

Definition

An instance of this DRM class is a specialized <Control Link> instance used to provide the connection between an ordered aggregation of <Expression> instances and the target fields of the <LSR 3D Location> instances that aggregate it.

Example

1. Consider a building <Model> that may be instanced on terrain polygons that are at various different orientations. Each building wall shall meet the terrain, leaving no gaps. This means that the lengths of the building's walls shall be adjusted by different amounts in each instance to match the slope of the ground.

   The location of each <Vertex> at the base of a wall <Polygon> can be adjusted by using an <LSR 3D Location Control Link> aggregated by the <LSR 3D Location> that specifies the <Vertex>'s location. Each <LSR 3D Location Control Link> would itself aggregate a <Variable>, which would specify the new location value. These <Variables> shall be set separately for each instance to match the terrain upon which the instance is positioned. This calls for the <Variables> to be set from outside the building <Model>, so all of these <Variables> in the building <Model> shall be associated with the <Model>'s <Interface Template>.

Notes

Fields Notes

description

 The description field specifies a text description of the given
 <Control Link> instance's purpose.

u_expr_index

 The u_expr_index field identifies a component <Expression>, the
 value of which specifies that of the coordinate.u field of the
 affected <LSR 3D Location> instances. If this index is 0, the
 coordinate.u field is not controlled.

v_expr_index

 The v_expr_index field identifies a component <Expression>, the
 value of which specifies that of the coordinate.v field of the
 affected <LSR 3D Location> instances. If this index is 0, the
 coordinate.v field is not controlled.

w_expr_index

 The w_expr_index field identifies a component <Expression>,
 the value of which specifies that of the coordinate.w field
 of the affected <LSR 3D Location> instances. If this index
 is 0, the coordinate.w field is not controlled.
