Syntax
class FMeshSurfaceUVSampler
Remarks
FMeshSurfaceUVSampler computes FMeshUVSampleInfo's on a given mesh at given UV-space positions, this info can then be used by an external function to compute some application-specific sample.
Note: This class is similar to TMeshSurfaceUVSampler (the "old" class) but provides a more convenient API. This class computes the sample info and that's it. The old class computes the sample info internally but also immediately forwards it to an application-specific sampling function which must be provided as a callback and hence has a fixed signature and requires that the sample type is passed as a template parameter. Also the old class is more awkward to use when sampling multiple things, see the documentation of TMeshSurfaceUVSampler for more details.
