transform

Go to: Attributes.

transform nodes are dagNodes that are used to group and transform other dagNodes. All dagNodes that are not transform nodes in Maya must exist as a child of some transform node.

   Rotate:
                If the rotationInterpolation attribute specifies quaternion
                interpolation, use the following OpenMaya API calls to construct
                the matrix:
                        Mquaternion q( rx, ry, rz, rw )
                        R  = q.asMatrix()

                Otherwise, for Euler-angle rotation use:
                        R  = RX * RY * RZ  (Note: order is determined by rotateOrder)

                        RX = |  1    0    0    0 |     RY = |  cy   0   -sy   0 |
                                 |  0    cx   sx   0 |          |  0    1    0    0 |

                        RZ = |  cz   sz   0    0 |     sx = sin(rx), cx = cos(rx)
                                 | -sz   cz   0    0 |     sy = sin(ry), cx = cos(ry)
                                 |  0    0    1    0 |     sz = sin(rz), cz = cos(rz)

In other words, transformations to its parent will not affect the world-space position of this transform and the parentMatrix attribute on this transform will return the identity matrix. This is primarily used when grouping objects with their construction history to prevent double transformations on the output object.

Boolean indicating whether the rotate pivot point for this transform should be displayed.

Boolean indicating whether the local rotation axis for this transform should be displayed.
dynamics (dyn)	bool	false
When connected, this attribute indicates that this transform is part of a dynamics simulation.

This attribute indicates the default manipulator that should be shown when this object is selected and the show manipulator tool is active. Valid values are 0=no default manipulator, 1=translation, 2=rotation, 3=scale. 4=transform, 5=global default, 6=smart, 7=specified
specifiedManipLocation (sml)	generic typed data	NULL
When showManipDefault is set to specified, the node that is connected to this attribute will be used to determine the type of manipulator to show
rotateQuaternion (rq)	double4

rotateQuaternionX (rqx) double 0.0 X channel of quaternion-based rotation (q=Xi+Yj+Zk+W). This attribute is only valid if the object is driven by quaternion animation curves.

To use this attribute, connect it to rotateX's associated paramCurve's ".rawValue" attribute.
rotateQuaternionY (rqy) double 0.0 Y channel of quaternion-based rotation (q=Xi+Yj+Zk+W). This attribute is only valid if the object is driven by quaternion animation curves.

To use this attribute, connect it to rotateY's associated paramCurve's ".rawValue" attribute.
rotateQuaternionZ (rqz) double 0.0 Z channel of quaternion-based rotation (q=Xi+Yj+Zk+W). This attribute is only valid if the object is driven by quaternion animation curves. It is not used to control the object's rotation, but can be used to query the rotation in quaternion space. To use this attribute, connect it to rotateZ's associated paramCurves ".rawValue" attribute.
rotateQuaternionW (rqw) double 0.0 W channel of quaternion-based rotation (q=Xi+Yj+Zk+W). This attribute is only valid if the object is driven by quaternion animation curves. To use this attribute, connect it to one is the rotation animCurve's ".quaternionW" attributes.
