Hi List<br><br>I&#39;ve been working with pix_multiblob to affect layers in 3D. I&#39;m managing to get an erratic signal from it, which from my point of view, represents great success! ; )<br><br>However, there are few areas I am still confused about. First of all, I am unsure of how to extract muliple co-ordinates from [pix_multiblob]. I understand that the data from multiblob is collated within a matrix. I am able to see this in the pd window when I print. However, I am unsure how to use a matrix. Is there a certain object that I should be sending to from [pix_multiblob]? And in turn, how would I convert the matrix into xy co-ordinates.<br>
<br>In the archives I found a response to similar a question saying there was a gem example with matrix and multiblob, but I can not seem to find it...<br><br>Also...<br><br>I am trying to use the various xy co-ordinates to trigger animations. However, I am unsure of how to animate with Pd. I noticed that [splinepath] does something similar to what I am looking for. This seems to be based on array&#39;s. However, looking at the help data for array&#39;s has not made it any clearer. Is there a way of inputting a list of co-ordinates that act as a path for an image to follow?<br>
<br>One last thing...<br><br>How can I adjust transparency/opacity in PD, I can not find an object that does this.<br><br>Hope thats not too many questions. And is it easier for the list if I divide questions up (for archive purposes perhaps)?<br>
<br>Thanks in advance<br>Simon<br><br>
