Detailed Description

Describes one or more authored display representations for an rprim. Display opinions are separated by the topology index they represent. This allows the application to specify one or more topological representations for a given HdRprim. For some visualizations, an application may choose to provide an opinion for the display of the refined surface, the unrefined hull and the points separately from the rprim's authored opinions. HdReprSelector allows these opinions to compose/merge into a final composite representation to be used for rendering.

Member Function Documentation

HD_API bool HdReprSelector::AnyActiveRepr ( ) const

Returns true if any of the topology tokens is valid, i.e., neither empty nor disabled.

HD_API HdReprSelector HdReprSelector::CompositeOver ( const HdReprSelector under) const

Returns a selector that is the composite of this selector 'over' the passed in selector. For each token that IsEmpty in this selector return the corresponding token in the passed in selector. Effectively this performs a merge operation where this selector wins for each topological index it has an opinion on.

HD_API bool HdReprSelector::Contains ( const TfToken reprToken) const

Returns true if the passed in reprToken is in the set of tokens for any topology index.

HD_API char const* HdReprSelector::GetText ( ) const
HD_API size_t HdReprSelector::Hash ( ) const
HD_API bool HdReprSelector::IsActiveRepr ( size_t  topologyIndex) const

Returns true if the topology token at an index is active, i.e., neither empty nor disabled.
