Syntax

template<typename AttribValueType, int AttribDimension>
class TDynamicMeshTriangleAttribute : public TDynamicAttributeBase< FDynamicMesh3 >

Remarks

TDynamicMeshTriangleAttribute is an add-on to a FDynamicMesh3 that allows for per-triangle storage of an attribute value.

The FDynamicMesh3 mesh topology operations (eg split/flip/collapse edge, poke face, etc) can be mirrored to the overlay via OnSplitEdge(), etc.
