OdGeScale3d Class

Class Hierarchy

Syntax

C++

class OdGeScale3d;

GeScale3d.h

This class represents scaling transformations (scale vectors) in 3D space.

OdGeScale3d may be viewed as an array[3] of doubles.

Corresponding C++ library: TD_Ge

	Name	Description
	OdGeScale3d	This is the overview for the OdGeScale3d constructor overload.

OdGeScale3d Data Members

	Name	Description
	kIdentity	Multplicitive identity scale.
	sx	X scale factor.
	sy	Y scale factor.
	sz	Z scale factor.

OdGeScale3d Methods

	Name	Description
	extractScale	Returns the scale vector corresponding to the lengths of the column vectors of the transformation matrix.
	getMatrix	Returns the transformation matrix equivalent to this scale vector.
	inverse	Returns the inverse of this scale vector.
	invert	Sets this scale vector to its inverse, and returns a reference to this scale vector.
	isEqualTo	Returns true if and only if scaleVec is identical to this one, within the specified tolerance.
	isProportional	Returns true if and only if the scaling matrix corresponding to this scale vector isUniScaledOrtho ().
	isValid	Returns true if this scale vector has nonzero coordinates or false if at least one coordinate is zero.
	postMultBy	Sets this scale vector to the product (this scale vector) * (rightSide), and returns a reference to this scale vector.
	preMultBy	Sets this scale vector to the product leftSide * (this scale vector), and returns a reference to this scale vector.
	removeScale	Returns the scale vector corresponding to the lengths of the column vectors of the transformation matrix, and sets the scale factor of the matrix to 1 .
	set	Sets this scale vector to the specified X and Y factors, and returns a reference to this vectors.
	setToProduct	This is the overview for the setToProduct method overload.

OdGeScale3d Operators

	Name	Description
	!=	Inequality operator for the OdGeScale3d object. Returns true if this scale vector is not equal to the input scale vector.
	*	This is the overview for the * operator overload.
	*=	This is the overview for the *= operator overload.
	[]	This is the overview for the [] operator overload.
	==	Equality operator for the OdGeScale3d object. Returns true if this scale vector is equal to the input scale vector.
	OdGeMatrix3d	Returns the equivalent 3D tranformation matrix.
