Description

This class represent the object transform matrix data. This class provides access to RLPy's internal 4x4 matrix operators and related functions.

See also: RMatrix4

Operators

+

The "addition" operator.

See Also: +=

 1 matrix_a = RLPy.RMatrix4( 2, 0, 0, 0,
 2                           0, 2, 0, 0,

 8                           2, 2, 2, 1 )
 9 transform =  RLPy.RTransform().From( matrix_a ) + RLPy.RTransform().From( matrix_b )
10 
11 print( transform.Matrix().GetRow(0)[0] == 2*3 ) # true

15 print( transform.Matrix().GetRow(3)[1] == 2+2 ) # true
16 print( transform.Matrix().GetRow(3)[2] == 3+2 ) # true

==

The "equal to" operator.

See Also: !=

1 transform_identity = RLPy.RTransform(RLPy.RTransform.IDENTITY)
2 print( transform_identity == transform_identity ) # true

!=

The "not equal to" operator.

See Also: ==

1 transform_identity = RLPy.RTransform(RLPy.RTransform.IDENTITY)
2 print( transform_identity != transform_identity ) # false

+=

The "addition assignment" operator.

See Also: +

Matrix (self)

Get 4x4 matrix from this transform.

Returns

A 4x4 matrix - RMatrix4
1 matrix4 = RLPy.RMatrix4( 0,-1, 0, 0, 
2                         -1, 0, 0, 0,

IsIdentity (self)

Check if this transform is equal to identity transform. Identity transform corresponds to "no transform" - the object is perfectly aligned with the world or parent axes and positioned at the origin.

Returns

True if the transform is equal to identity transform, else False - bool
1 matrix4 = RLPy.RMatrix4( 1, 0, 0, 0,
2                          0, 1, 0, 0,

5 transform_data = RLPy.RTransform().From( matrix4 )
6 print( transform_data.IsIdentity() ) # True

Scale (self)

Form a scale matrix from this transform.

Returns

A 3x3 scale matrix from this transform - RMatrix3
1 scale = RLPy.RVector3( 4, 5, 6 )
2 matrix4 = RLPy.RMatrix4().FromRTS( RLPy.RMatrix3.IDENTITY,

GetSR (self)

Form a 3x3 matrix with rotation and scale from this transform.

Returns

A 3x3 matrix from this transform - RMatrix3
 1 scale  = RLPy.RVector3( 2, 2, 2 )
 2 rotate = RLPy.RMatrix3( -0,-0, 1,
