openMASH

class openMASH.MASHData(nodeName)

MASHData prepares data from a MASH network, ready for use with the MASH_Python node.

It also provides utility funcitons to make working with this data easier.

This class uses the MAYA Python API 2.0

count()

Returns the number of points in the MASH network.

createLocalMatrix(position, rotation, scale)

Returns a local MTransformationMatrix

getColorSet(setName)

Returns a MASH colour set of the specified name.

getData()

Internal - called from init. Gets the data from the in attributes and sets it to the class variables. | It is highly unlikely you will need to use this.

getDoubleArray(attributeName)

Returns a double array from the specified attribute name

getFalloff(index)

Returns a doubleArray of strengths from a falloff object at the index specified. This happens through the old Maya Python API due to lack of support for MFnFloatArrayData in 2.0

getFalloffsCount()

Returns the number of falloff objects.

getFrame()

Returns the current frame. We do this via the MAnimControl and so it works reguardless of the state of the time attribute.

getIntArray(attributeName)

Returns an int array from the specified attribute name

getMatrix(pointId)

Returns an MTransformationMatrix of the specified point.

getNamedArray(channelName, typeName)

Returns a vector array or Python list (for doubles) from the specified channel name.

Please note, you can only read data in this way.

:param – channelName: The desired channel. Use getNamedArrays() to see what channels you can get.

:param – typeName: “double” and “vector” are valid strings here.

getNamedArrays()

Returns all the array names in the dynamic array data

getVectorArray(attributeName)

Returns a vector array from the specified attribute name

resizeMArray(l, newsize, obj=None)

If growing:

Rather then using .setLength() we append to an MArray one by one in order to give ourselves a default value.

If shrinking:

Delete the unneeded entries.

setData()

Set the data to the out attributes.

Calling this at the end of your script is required for the MASH Python node to function correctly.

setDoubleArray(attributeName, array)

Sets the specified double array to the specified attribute name

setIntArray(attributeName, array)

Sets the specified int array to the specified attribute name

setMatrix(matrix, pointId)

Sets the MTransformationMatrix for the specific point.

setPointCount(count)

Resizes all the out arrays with default values - thus changing the point count.

setVectorArray(attributeName, array)

Sets the specified vector array to the specified attribute name
