# class SurfaceMapper

ISurfaceMapper creates a mapping image between two user-defined geometries. The mapper basically looks for the source geometry in the inverse normal direction from the outwardly offset destination geometry, and maps pixels accordingly. This means that you can modify the normals of the destination geometry to adjust the search direction to your liking. The geometries can either be set as IGeometryDatas or as the root nodes of scenes. If both are set, the scene is used. If only a single source or a destination is set, or if the source and destination are the same scene or geometry, the surface mapper will map the mesh onto itself.

# Properties

Property Description
DestinationGeometry The destination geometry data.
DestinationScene The scene used for the surface transfer destination.
RecalculateSearchDirection If set, the search direction from the destination mesh to the source mesh will be determined by an internal normal calculation with the specified hard edge angle. If false, the search direction will be determined by the existing normals of the destination geometry.
SearchDirectionHardEdgeAngle The hard edge angle in degrees. If RecalculateSearchDirection is on, the search direction from the destination mesh to the source mesh will be determined by an internal normal calculation with the specified hard edge angle. If false, the search direction will be determined by the existing normals of the destination geometry.
SearchDistance The search distance. If the source geometry is found within this distance from the destination geometry, it will be mapped. If negative, it will be set to a sane default internally, based on the mesh size.
SearchOffset The search offset. This is how far out from the destination geometry the search for the source geometry will begin, propagating inwardly for the length of SearchDistance. If negative, it will be set to a sane default internally, based on the mesh size.
SourceGeometry The source geometry data.
SourceScene The scene used for the surface transfer source.

# Methods

Method Description
GetClass Get the name of the SurfaceMapper class.
GetMappingImage The mapping image.
GetMappingImageSettings The mapping image settings. Currently, the only applicable settings for this mapper is texcoordlevel, texcoordname, size, and supersampling settings.
IsA Returns true if SurfaceMapper is a or is a descendant of the class named as the type parameter.
IsNull Returns true if the SurfaceMapper object is invalid.
RunSurfaceMapping Runs the surface mapping.

# Static methods

Method Description
IsClassA Returns true if the class is a or is a descendant of the class named as the type parameter.
SafeCast SafeCast makes sure the input object is of a class that can be cast into spSurfaceMapper, and if this is the case, returns the object cast into spSurfaceMapper.
