Member Function Documentation

Extract() [1/2]

eVision.Easy3D.E3DTransformMatrix eVision.Easy3D.EPrincipalAxisExtractor.Extract	(		self,
		eVision.Easy3D.EPointCloud	pc )

Computes the eVision.Easy3D.E3DTransformMatrix for a given eVision.Easy3D.EPointCloud.

This will compute the PCA, then select the direction of each axis of the basis so that this basis is as close as possible as the reference transform.

Optionally returns the standard deviation along the 3 axis.

Parameters

pc	Input point cloud.

Extract() [2/2]

eVision.Easy3D.E3DTransformMatrix eVision.Easy3D.EPrincipalAxisExtractor.Extract	(		self,
		eVision.Easy3D.EPointCloud	pc,
		eVision.Easy3D.E3DPoint	stdDev )

Computes the eVision.Easy3D.E3DTransformMatrix for a given eVision.Easy3D.EPointCloud.

This will compute the PCA, then select the direction of each axis of the basis so that this basis is as close as possible as the reference transform.

Optionally returns the standard deviation along the 3 axis.

Parameters

pc	Input point cloud.
stdDev	Variable to store the X, Y and Z components of the standard deviation.

HasReferenceTransformSet()

bool eVision.Easy3D.EPrincipalAxisExtractor.HasReferenceTransformSet

(

self

)

Returns 'true' if a reference transform (eVision.Easy3D.E3DTransformMatrix) has been set explicitly.

Load() [1/2]

None eVision.Easy3D.EPrincipalAxisExtractor.Load	(		self,
		eVision.ESerializer | None	serializer )

Loads the eVision.Easy3D.EPrincipalAxisExtractor object configuration.

The given eVision.ESerializer must have been created for reading.

Parameters

serializer

The serializer.

Load() [2/2]

None eVision.Easy3D.EPrincipalAxisExtractor.Load	(		self,
		str	path )

Loads the eVision.Easy3D.EPrincipalAxisExtractor object configuration.

The given eVision.ESerializer must have been created for reading.

Parameters

path	The file path.

ReferenceTransform() [1/2]

eVision.Easy3D.E3DTransformMatrix eVision.Easy3D.EPrincipalAxisExtractor.ReferenceTransform

(

self

)

Sets/Gets the reference transform (eVision.Easy3D.E3DTransformMatrix).

If not set, it will use the main basis as reference to select the direction of each axis of the new basis.

ReferenceTransform() [2/2]

eVision.Easy3D.EPrincipalAxisExtractor.ReferenceTransform	(		self,
		eVision.Easy3D.E3DTransformMatrix	value )

Sets/Gets the reference transform (eVision.Easy3D.E3DTransformMatrix).

If not set, it will use the main basis as reference to select the direction of each axis of the new basis.

Save() [1/2]

None eVision.Easy3D.EPrincipalAxisExtractor.Save	(		self,
		eVision.ESerializer | None	serializer )

Saves the eVision.Easy3D.EPrincipalAxisExtractor object configuration.

The given eVision.ESerializer must have been created for writing.

Parameters

serializer

The eVision.ESerializer object that is written to.

Save() [2/2]

None eVision.Easy3D.EPrincipalAxisExtractor.Save	(		self,
		str	path )

Saves the eVision.Easy3D.EPrincipalAxisExtractor object configuration.

The given eVision.ESerializer must have been created for writing.

Parameters

path	The file path.

UnsetReferenceTransform()

None eVision.Easy3D.EPrincipalAxisExtractor.UnsetReferenceTransform

(

self
