<html><head></head><body><div style="font-family: Verdana;font-size: 12.0px;"><div>Hi Sebastian and Logan,
<div>
<div> </div>
<div>thank you a lot for your help and i apologize for my late answer!</div>
<div>Unfortunately I still could not solve the problem. I tried both suggestions:</div>
<div>With <strong>actor</strong>.getCenter() I get the default-values (0,0,0) for each actor. So I tried to get the information of the dataset as you suggested:</div>
<div> </div>
<div> dataset = mapper.getInputData();</div>
<div> bounds = dataset.getBounds();</div>
<div> </div>
<div>By doing so I get the following error massage:</div>
<div><strong> "getBounds called on an array with components of 1"</strong></div>
<div> </div>
<div>The output of getBounds remains default because of the error.</div>
<div> </div>
<div>As I could not find any solutions yet, I would be grateful for any help!</div>
<div> </div>
<div>Thank you</div>

<div name="quoted-content">
<div>Hi Katrin,
<div> </div>
<div>The actor position only describe the relative position to the data, that's why by default they are always (0,0,0).</div>
<div>Which means its your source or dataset that has the information about the position that you are looking for.</div>
<div> </div>
<div>For example to find the bounds of a rendered dataset you can do as follow.</div>
<div> </div>
<div>dataset = mapper.getInputData();</div>
<div>bounds = dataset.getBounds();</div>
<div> </div>
<div>// bounds is an array as follow:</div>
<div>// [ minX, maxX, minY, maxY, minZ, maxZ]</div>
<div> </div>
<div>Hope that helps,</div>

<div>Dear all,</div>
<div> </div>
<div>I am using a visualization of several actors with VTK-js. Unfortunately, when using <em>actor.getPosition() </em>I always get [0,0,0] as a result, no matter which actor I checked, although they appear on different positions in my rendering window.</div>
<div>How can I get the real positions or centers of the different actors?</div>
<div> </div>
<div>As I am completely new to VTK-js and I could not find any solutions to my problem, any help would be great!</div>
<div> </div>
<div>Thank you</div>
