set_vertices()

void MayaFlux::Nodes::Network::PathOperator::set_vertices

(

const std::vector< LineVertex > &

vertices

)

Replace every control point, in extract_vertices() order, keeping the paths.

Parameters

vertices

One vertex per control point across all paths.

When the count differs from the current total this falls back to initialize().
