FSpriteGeometryCollection()		SpriteEditorOnlyTypes.h

Name	Type	Remarks	Include Path	Unreal Specifiers
AlphaThreshold	float	Alpha threshold for a transparent pixel (range 0..1, anything equal or below this value will be considered unimportant)	SpriteEditorOnlyTypes.h	Category=PolygonData EditAnywhere AdvancedDisplay
bAvoidVertexMerging	bool	Experimental: Hint to the triangulation routine that extra vertices should be preserved.	SpriteEditorOnlyTypes.h	Category=PolygonData EditAnywhere AdvancedDisplay
DetailAmount	float	Amount to detail to consider when shrink-wrapping (range 0..1, 0 = low detail, 1 = high detail)	SpriteEditorOnlyTypes.h	Category=PolygonData EditAnywhere AdvancedDisplay
GeometryType	TEnumAsByte< ESpritePolygonMode::Type >	The geometry type (automatic / manual)	SpriteEditorOnlyTypes.h	Category=PolygonData EditAnywhere
PixelsPerSubdivisionX	int32	Size of a single subdivision (in pixels) in X (for Diced mode)	SpriteEditorOnlyTypes.h	Category=PolygonData EditAnywhere
PixelsPerSubdivisionY	int32	Size of a single subdivision (in pixels) in Y (for Diced mode)	SpriteEditorOnlyTypes.h	Category=PolygonData EditAnywhere
Shapes	TArray< FSpriteGeometryShape >	List of shapes.	SpriteEditorOnlyTypes.h	Category=PolygonData EditAnywhere AdvancedDisplay
SimplifyEpsilon	float	This is the threshold below which multiple vertices will be merged together when doing shrink-wrapping. Higher values result in fewer vertices.	SpriteEditorOnlyTypes.h	Category=PolygonData EditAnywhere AdvancedDisplay

void AddCircleShape ( FVector2D Position, FVector2D Size )		SpriteEditorOnlyTypes.h
void AddRectangleShape ( FVector2D Position, FVector2D Size )		SpriteEditorOnlyTypes.h
bool ConditionGeometry()	Conditions this geometry collection (turning Polygons back to Boxes if they meet the definition of a box, etc...) Returns true if something was modified	SpriteEditorOnlyTypes.h
void Reset()	Empties this geometry collection, resetting the GeometryType to TightBoundingBox.	SpriteEditorOnlyTypes.h
void Triangulate ( TArray< FVector2D >& Target, bool bIncludeBoxes ) const	Takes all polygon shapes and generates a list of triangles from them.	SpriteEditorOnlyTypes.h
