API Reference > geometry-core > Polyface > AuxChannelDataType AuxChannelDataType Enumeration The data types of AuxChannel. The scalar types are used to produce thematic vertex colors. Members Name Value Description Scalar 0 General scalar type - no scaling is applied if associated Polyface is transformed. Distance 1 Distance (scalar) scaling is applied if associated Polyface is scaled. 3 Data values (x,y.z) per entry. Vector 2 Displacement added to vertex position. Transformed and scaled with associated Polyface. 3 Data values (x,y.z) per entry., Normal 3 Normal -- replaces vertex normal. Rotated with associated Polyface transformation. 3 Data values (x,y.z) per entry. Defined in core/geometry/src/polyface/AuxData.ts Line 19 Last Updated: 13 June, 2024
