Description

Class
  • <DRM Light Rendering Properties Control Link>

Superclass

Subclass
  • None.

Definition

An instance of this DRM class is a specialized <DRM Control Link> providing the connection between a <DRM Light Rendering Properties> instance and the <DRM Expressions> that are used to determine whether the <DRM Light Rendering Properties> is active and and the value of its candela_value field.

The active_expr_index, candela_value_expr_index, <DRM lower_candela_value_expr_index>, and upper_candela_value_expr_index are 1-based indices into the ordered aggregation of <DRM Expression> instances, and are used to select the specific <DRM Expression> instances that define the target <DRM Light Rendering Properties>' active_light_value and candela_value fields.

Clarifications

1 This is a text description of the given <DRM Control Link> instance's purpose.

2 This specifies which component <DRM Expression>, if any, specifies the active_light_value of the target <DRM Light Rendering Properties> instances. If active_expr_index is zero (0), the active_light_value field values of the target instances are not controlled.

3 This specifies which component <DRM Expression>, if any, specifies the candela_value of the target <DRM Light Rendering Properties> instances. If candela_value_expr_index is zero (0), the candela_value field values of the target instances are not controlled.

4 This specifies which component <DRM Expression>, if any, specifies the lower limit of the candela_value of the target <DRM Light Rendering Properties> instances. If lower_candela_value_expr_index is zero (0), no lower limit is specified.

Note that if candela_value_expr_index is zero, the candela_value field values of the target instances are not controlled, so this value would also be zero.

5 This specifies which component <DRM Expression>, if any, specifies the upper limit of the candela_value of the target <DRM Light Rendering Properties> instances. If upper_candela_value_expr_index is zero (0), no upper limit is specified.

Note that if candela_value_expr_index is zero, the candela_value field values of the target instances are not controlled, so this value would also be zero.
