is_concatenable_topology()

constexpr bool MayaFlux::Portal::Graphics::is_concatenable_topology ( PrimitiveTopology  topology )

constexprnoexcept

Whether two adjacent spans of this topology can be concatenated without altering the primitives they assemble.

List topologies assemble each primitive from its own fixed-size group of consecutive vertices, so appending one span to another adds primitives and leaves existing ones untouched. Strip and fan topologies assemble each primitive from vertices shared with its predecessor, so concatenation fabricates an extra primitive spanning the join.
