Syntax

class FAbcPolyMesh : public IAbcObject

Variables

	Name	Description
bool	bConstantTopology	Flag whether or not this object has constant topology (used for eligibility for PCA compression)
bool	bConstantTransformation	Flag whether or not this object has a constant world matrix (used whether to incorporate into PCA compression)
bool	bConstantVisibility	Flag whether or not this object has a constant visibility value across the entire animated range
bool	bFirstFrameVisibility	Whether or not the mesh is visible in the first Frame
bool	bReturnFirstSample	Whether or not to just return FirstSample
bool	bReturnTransformedFirstSample	Whether or not to just return the transformed FirstSample
bool	bShouldImport	Whether or not this Mesh object should be imported
FBoxSphereBound...	ChildBounds
TArray< FString...	FaceSetNames	Array of face set names found for this object
FAbcMeshSample ...	FirstSample	Initial mesh sample for this object in first frame with available data
const Alembic::...	PolyMesh	Alembic representation of this object
FAbcMeshSample ...	ResidentSamples	Resident set of Mesh Samples for this object, used for parallel reading of samples/frames
bool[MaxNumberO...	ResidentVisibilitySamples
ESampleReadFlag...	SampleReadFlags	Bitmask read flag used for skipping constant vertex attributes while reading samples
const Alembic::...	Schema	Schema extracted from Poly Mesh object
FBoxSphereBound...	SelfBounds	Cached self and child bounds for entire duration of the animation
FAbcMeshSample ...	TransformedFirstSample	Initial mesh sample for this object in first frame with available data, transformed by first available matrix

Functions

	Name	Description
void	CalculateNormalsForSample ( FAbcMeshSample* Sample )	Calculate normals for sample according to available data and user settings
const FAbcMe...	GetFirstSample()	Returns the first sample available for this object
const FAbcMe...	GetSample ( const int32 FrameIndex )	End IAbcObject overrides Returns sample for the given frame index (if it is part of the resident samples)
ESampleReadF...	GetSampleReadFlags()	Returns the value of the bitmask used for skipping constant vertex attributes while reading samples
