VertexFieldProcessor()

MayaFlux::Buffers::VertexFieldProcessor::VertexFieldProcessor ( std::shared_ptr< Nodes::Network::GpuFieldOperator >  field_operator )

explicit

Parameters

field_operator

Operator supplying the generated spec. Must already carry at least one binding and a layout with a position attribute, since the shader is compiled during construction. Throws std::invalid_argument when build_spec() yields nothing.
