◆ AddToDocAsUCS

Number SMatrix::AddToDocAsUCS	(	String	Name,
		Boolean	IsActivated
	)

slot

To add the matrix to the scene as an UCS with the given name.

Note: The matrix used for the UCS should not have null rows. Also, the vectors created from the rows should not be parallel.

1	The matrix is not well defined

[in]	Name	Name of the UCS
[in]	IsActivated	True if the UCS should be activated

◆ ApplyTransformation

		Boolean	iAttractReversedNormals
	)

staticslot

Calculate the matrix that should be applied to each component of a set to make a best fit of all the components in a least squares sense.

Note: This function analyzes the overlapping area of the objects. It means that an overlapping area must exist. Otherwise the best fit operation may give a non relevant result or no result at all (identity matrix).; If you use this function with clouds, the cloud must represent a surface in order to project point on this cloud. If you have only a few points (less than 100 of overlapping area) it may be difficult for the function to approximate a surface and to make statistic evaluations. The result may be disappointing or you may have no result at all (identity matrix). If you have only a few points in cloud number 1 to best fit with the same number of points matching in cloud number 2, you should prefer the function InitBestAlign().; Before calling the function, the component should be roughly prepositioned so they are not too far from each other.

Return values

Array.ErrorCode	The error code: 0 OK, no error 1 Invalid list of component or bad / incomplete initialization or impossible to initialize.
Array.MatrixTbl	Array of resulting matrices defining new component positions, in the same order as the input component table. The first component being assumed as immobile, the first matrix is initialized with the identity matrix.
Array.StdDeviationTbl	the registration standard deviation error of each component
Array.MeanErrorTbl	the registration mean error of each component

Note: If the fitting error is small, there is a high chance that the position of the component is correct. A high fitting error can come from several factors:

The position of the object is not correct.
The component is a very "noisy" shape (many measurement errors).
The shape (or scale) of the different components are different.

If you register several components together (BestFitType==1), do not forget that if one of the component has a "bad shape" so that it cannot fit correctly with its neighbors, this will also affect the fitting error of the neighbors. However, there is a high chance that the standard deviation of the "worst component" is the highest.

If you register several components together (BestFitType==1), Array.StdDeviationTbl[0] will contain a value although component zero do not moves. This represent the fitting error of component zero with its neighbors in the overlapping areas. If you register all components on the first (BestFitType==0), or if there are only two components, Array.StdDeviationTbl[0] is returned with a null value.

Parameters

[in]	CompTable	Table of components to best fit together The first component of the list is assumed to be immobile. Valid components in the list are: SCloud, SPoly, SMultiline, SCADSurface
[in]	ThresDist	Ignore the part of the components whose distance with other components is greater than this threshold. If a complete session is done and BestFitCompute has not been called previously, this value can be set to null to tell the function to take 1/100 of the greatest size. The parameter "ThresDist" is very critical To explain this value, we will take the comparison of a "magnet". When you make the best fit, you "attract" some parts of the shape so that they get closer and to minimize a distance. However, the fitting between the shapes will be correct only if the "attraction" is done between 2 parts representing the same shape in the different objects to fit. In other words, if you attract 2 parts at the opposite extremities of the object to fit, there is a high chance that the position at the end will be incorrect. To avoid this, the "magnet" must limit his attraction to a certain distance and it is the goal of this parameter. The value to set should be in relation with the misalignment error before entering in the command. In other words "how far are the object to align?". In this value, you must also take in account the measurement accuracy and the noise thickness, if any.
[in]	BestFitType	Which type of best fit should be done ? 0: Component 1 to n are best fitted with the first component (number 0 that is immobile) 1: Best fit all together. (component number i is best fitted with all other n-1 components). This option is ignored if there are only 2 components. 2: Component 1 to n are best fitted with the first component (number 0 that is immobile) and a SCALE is applied on components 1 to n
[in]	ConstraintBitMask	Transformation constraints (bit mask option) TRANSLATION_X (ConstraintBitMask & TRANSLATION_X) Allow the translation along the X-axis TRANSLATION_Y (ConstraintBitMask & TRANSLATION_Y) Allow the translation along the Y-axis TRANSLATION_Z (ConstraintBitMask & TRANSLATION_Z) Allow the translation along the Z-axis ROTATION_X (ConstraintBitMask & ROTATION_X) Allow the rotation around the X-axis ROTATION_Y (ConstraintBitMask & ROTATION_Y) Allow the rotation around the Y-axis ROTATION_Z (ConstraintBitMask & ROTATION_Z) Allow the rotation around the Z-axis
[in]	FixedPoint	Fixed point. If not null, this point will not move during the rotation.
[in]	ConstraintAxis	Axis of constraint. If not null, the translation will be guided by this vector.
[in]	iAttractReversedNormals	Should we make attraction between surfaces having reversed normals ? false No, do not consider overlapping when surfaces have not the same orientation true Yes, make an attraction between surfaces even if they do not have the same orientation. Note: This option will only affect meshes and clouds containing scanning direction information
