def gear.xsi.transform.getFilteredTransform	(		t,
			translation = True,
			rotation = True,
			scaling = True
	)

Retrieve a transformation filtered.

Parameters

t	SITransformation - Reference transformation.
translation	Boolean - True to match translation.
rotation	Boolean - True to match rotation.
scaling	Boolean - True to match scaling.

Returns

SITransformation - The filtered transformation

def gear.xsi.transform.getGlobalPositionFromObjects

(

collection

)

Get the global translation of each object in list or collection.

Parameters

collection

List of X3DObject or XSICollection.

Returns

List of SIVector3 - The global translation.

def gear.xsi.transform.getRotationFromAxis	(		in_a,
			in_b,
			axis = "xy",
			negate = False
	)

ROTATION.

setRefPose =============================================

def gear.xsi.transform.getSymmetricalTransform	(		t,
			axis = "yz"
	)

Get the SITransformation.

Parameters

t	SITransformation - The transform to symmetrize.
axis	SIVector3 - Mirroring axis.

Returns

SITransformatin - The newy created transform

def gear.xsi.transform.getTransformFromPosition

(

position

)

Get a SITransformation with translation equal the given position.

Parameters

position

SIVector3 - The position

Returns

SITransformatin - The newy created transform

def gear.xsi.transform.getTransformLookingAt	(		position,
			lookat,
			normal,
			axis = "xy",
			negate = False
	)

TRANSFORM.

getTransformLookingAt ================================== Get a transform that is oriented looking at another position.

Parameters

position	SIVector3 - The position of the object.
lookAtPos	SIVector3 - The position that the object is looking at.
upv	SIVector3 - Up vector direction.
negate	Boolean - True to create negative side transform.
axis	String - First the axis point at the look at position then the axe pointing to the up vector ("xy", "xz", "yx", "yz", "zx", "zy")

Returns

SITransformation - The newly created transform.

def gear.xsi.transform.matchGlobalTransform	(		target,
			source,
			translation = True,
			rotation = True,
			scaling = True
	)

Math the global transformation of target object to source.

Parameters

target	X3DObject - Target object. The one we apply the new transform to.
source	X3DObject - Source object.
translation	Boolean - True to match translation.
rotation	Boolean - True to match rotation.
scaling	Boolean - True to match scaling.

def gear.xsi.transform.setRefPose	(		obj,
			orientation = [0,
			negate = False
	)

KINEMATICS.

setRefPose ============================================= set the reference (neutral) pose of an object. Neutral translation and scaling and neutral orientation with offset.

Parameters

obj	X3DObject - The object.
orientation	List of Double - The object neutral pose orientation angles in degrees.
negate	Boolean - True to use with negative side.
