MPxLocatorNode and boundingBox

[Rémi Deletrain]

Hello everybody,

I made a new node dependent of "MPxLocatorNode". It works well.

I try to define boudingbox but this time Maya crash all the time ...

I fail to understand why.

Does anyone have the answer?

That is my code.

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

    def isBounded(self):

        """

        !@Brief Set this node with bounding box. See doc for more infos.

        """

        return True

    def boundingBox(self):

        """

        !@Brief Set boundingbox min and max of this node. See doc for more infos.

        """

        return OpenMaya.MBoundingBox(self.bb_min, self.bb_max)

with for exemple:

self.bb_min = [-1.0, 0.0, -1.0]

self.bb_max = [1.0, 0.0, 1.0]

this two variables is calculate with point position value

Which Maya? Which OS? Could you post a complete example to reproduce the problem?

Try initiailizing your bb_min and bb_max to (-1,-1,-1) and (1,1,1) respectively.  Also, you could, instead of doing all that work in another method,

do something like this in your boundingBox method if you save the points you're gathering in a list, or MPointArray.

def boundingBox(self):

   bbox = om.MBoundingBox()

for point in self.pointList: bbox.expand(point) return bbox

Hello Daniel,

Thank you for your answer.

I tried your solution but doesn't work either...

What's the error you're getting?  Is it a hard crash?  Are you positive it's the bounding box method causing the error?
