Signature | Parameters | Description |
---|---|---|
MTransformationMatrix() | Default constructor. Returns a new MTransformationMatrix object, set to the identity transformation. | |
MTransformationMatrix(src) | src - MTransformationMatrix or MMatrix | Returns a new MTransformationMatrix object with the same value as src. |
Signature | Parameters | Returns | Description |
---|---|---|---|
asMatrix(interp=1.0) | interp - float | MMatrix | Interpolates between the identity transformation and that currently in the object, returning the result as an MMatrix. When interp is 0.0 the result will be the identity matrix. When it is 1.0 the result will be the full transformation. If interp is less than 0.0 or greater than 1.0 the result will properly extrapolated. |
asMatrixInverse() | MMatrix | Returns the inverse of the matrix representing the transformation. | |
asRotateMatrix() | MMatrix | Returns the matrix which takes points from object space to the space immediately following the scale/shear/rotation transformations. | |
asScaleMatrix() | MMatrix | Returns the matrix which takes points from object space to the space immediately following scale and shear transformations. | |
isEquivalent(other, tolerance=kTolerance) | other -
tolerance - float |
bool | Inexact equality test. Returns true if this transformation's matrix is within tolerance of other's matrix. |
reorderRotation(order) | order - Rotation Order constant | Reference to self. | Reorders the transformation's rotate component to give the same overall rotation but using the new order or rotations. |
rotateBy(rot, space) | rot - MQuaternion or MEulerRotation

space - MSpace constant asQuaternion - bool |
Reference to self. | Adds the rotation represented by the four parameter values to the transformation's rotate component. If asQuaternion is True then seq must contain four floats representing the x, y, z and w components of a quaternion rotation. If asQuaternion is False then seq must contain three floats representing the x, y and z angles, followed by a Rotation Order constant, which together form an Euler rotation. |

rotationComponents(asQuaternion=False) | asQuaternion - bool | [x, y, z, order] or [x, y, z, w] | Returns a list containing the four components of the transformation's rotate component. If asQuaternion is True then the first three elements are the quaternion's unreal x, y, and z components, and the fourth is its real w component. If asQuaternion is False then the first three components are the x, y and z Euler rotation angles and the fourth is a Rotation Order constant. |
rotationOrder() | Rotation Order constant | Returns the order of rotations when the transformation's rotate component is expressed as an euler rotation. | |
