More fun with Python transformations

dan.husted — Thu, 16 Jul 2020 20:27:25 GMT

I would like access the local transformation matrix for a given node. My immediate need is to know if a node has an identity transformation, but I would like to the general process for accessing node data. The getWorldTransformation function will retrieve the global position of the node, but I am interested in the position data for the node itself.

I am currently able to access all the data in the "attachments" section of a node, but I an struggling to get to the "matrix" and "isIdentity" fields. And in general, how do I access the data for which there is no direct API? The node editor is a pretty good tool for seeing the node data, but accessing the data seems a bit cryptic to me.

Thanks in advance for ant help you can provide.

Hi,

try this:

matrix = node.fields().getMatrix("matrix")

It's working fine in my script.

The isIdentity field should be accessable in the same manner.

best regards

Jochen

Jochen,

Thanks so much for your response.

I would have sworn I had tried that combination among the dozens I when through. But this worked.
