[SOLVED] how to use node output as "param" for ImageFilter?

[mbarrow]

Hi,

I want to use the output field “position” of a mechanical object as the input field “param” in an ImageFilter node.
The problem is, only the x coordinates of “position” are passed as in [x,x,x… ]. I need [x,y,z x,y,z …]
What should I do?

<ImageContainer name="loader" filename="data/whitebeam.png" drawBB="false" />
<ImageFilter name="selectchannel" src="@loader" filter="21" param="0"/>
<ImageFilter name="extruder" inputImage="@selectchannel.outputImage" filter="20" param="@parent.position" inputTransform="-0.5000 -2.5000 0.0000 0.00 0.00 0.00 0.0100 0.0100 1.0000 0 1 0"/>

To anyone who has time to look at this, here is a link to the image in the code snippet: here is a 100×500 white beam png image

Cheers

Ignore this question. It makes no sense what I was trying to do.

Hi @mjbarrow

Data in SOFA can be connected if they have the same type.
If not, or if some processing is necessary, maybe consider going towards python no ?

Thanks for looking at this Hugo.

I had gotten confused about how the image filter works. I think this thread would be better of being deleted
