Enumeration Type Documentation

◆ DiffType

enum Ponca::DiffType : unsigned int

Flags defining which derivatives need to be computed.

Warning: Flags have to be combined using |

Enumerator
FitScaleDer	Flag indicating a scale differentiation.
FitSpaceDer	Flag indicating a space differentiation.
FitScaleSpaceDer	Flag indicating a scale-space differentiation.

Definition at line 33 of file enums.h.

◆ FIT_RESULT

enum Ponca::FIT_RESULT : unsigned char

Enum corresponding to the state of a fitting method (and what the finalize function returns).

Enumerator
STABLE	The fitting is stable and ready to use.
UNSTABLE	The fitting is ready to use but it is considered as unstable (if the number of neighbors is low for example).
UNDEFINED	The fitting is undefined, you can't use it for valid results.
NEED_OTHER_PASS	The fitting procedure needs to analyse the neighborhood another time.
CONFLICT_ERROR_FOUND	Multiple classes of the fitting procedure initialize the primitive. Should be treated as error.
NBMAX	Nb enums.
