I'd like to add a "MTransformationMatrix::rotateBy" to this code using another set of euler values - any ideas? Thanks
# Set some rotation values for comparison later:
mc.setAttr('%s.rotate'%node, 15, -45, 1000)
mc.setAttr('%s.scale'%node, 3, 3, 3)
# Change the rot order, to make sure returned euler values are correct:
mc.setAttr('%s.rotateOrder'%node, 3)
#-------------------------------------------
# Part 1: Get a MTransformationMatrix from an object for the sake of the example.
# You can use your own MTransformationMatrix if it already exists of course.
# get a MDagPath for our node:
selList = om.MSelectionList() # make a sel list # MSelectionList
selList.add(node) # add our node by name
mDagPath = om.MDagPath() # create an empty dag path # MDagPath
selList.getDagPath(0, mDagPath) # fill the dag path with our node
# Create a MFnTransform object for our MDagPath,
# and extract a MTransformationMatrix from it:
transformFunc = om.MFnTransform(mDagPath) # MFnTransform
mTransformMtx = transformFunc.transformation() # MTransformationMatrix
#MTransformationMatrix::rotateBy ( const MEulerRotation & e, MSpace::Space space, MStatus * ReturnStatus = NULL )
MTransformationMatrix::rotateBy ( const MEulerRotation & e, MSpace::Space space, MStatus * ReturnStatus = NULL )
#-------------------------------------------
# Part 2, get the euler values
# Get an MEulerRotation object
eulerRot = mTransformMtx.eulerRotation() # MEulerRotation
# note, we don't have to set the rot order here...
# Convert from radians to degrees:
angles = [math.degrees(angle) for angle in (eulerRot.x, eulerRot.y, eulerRot.z)]
print angles, "MTransformationMatrix"
