add_node()

void MayaFlux::Nodes::Network::PathOperator::add_node

(

std::shared_ptr< GpuSync::PathGeneratorNode >

node

)

Add an externally constructed PathGeneratorNode subtype to the operator.

Accepts any PathGeneratorNode subclass (e.g. LineSegmentNode) that was constructed and configured by the caller. The node is appended to m_paths and will participate in process(), get_vertex_data(), and extract_vertices() identically to nodes created by add_path().

compute_frame() is called once before insertion so the node's vertex buffer is populated on the first frame.

Parameters

node	Non-null shared_ptr to a PathGeneratorNode or subclass.
