There is several reasons for the composite operation to be included:<br>- Otherwise you need more nodes: set alpha (from mask) + alpha over<br>- One suplementary compositing method (processed frorground + composite without multiplying backgroung) for softer edges.<br>
- The edge blending blur is applied to the resulting composite, <br>- No way to mess up with the connexions. (choosing the "processed frorground" compositing method require the plate to be modified before the despill operation)<br>
<br>In global, my node can't replace the alpha over node (mine works with image that do not contain alpha channel, and the matte pulling operation is used to create an alpha channel)<br><br>But if the node is splitted, into differents nodes, the current alpha over node will need to be modified if we want the "processed foreground" compositing method. (we will need a "process foreground node" also)<br>
<br>In fact I really thing that it can be usefull in both forms (one complete node or 5 or 6 differents nodes), the second will be less "straight forward" but more flexible. The unique node is quick and simple allaround solution.<br>
<br>But as I said: I didn't got a lot of feedback on this matter.<br><br>xavier<br><br><div class="gmail_quote">2008/12/8 Roger Wickes <span dir="ltr"><<a href="mailto:rogerwickes@yahoo.com">rogerwickes@yahoo.com</a>></span><br>

Does your code provided a better, different, or redundant solution to the alpha-over node? If it is better, I would ask that we extract your code and use it to replace the current alpha-over node. If it is different, I would ask that we add it to the alpha-over node as a different method, selectable in the node as an algorithm/mode to use. If it is redundant, I would ask that it be removed, as it is redundant. <br>

hi,<br><br>Your build do not run on my machine (complain baout openal but it is installed)<br><br>I think for a maximum portablity you have to distribute all the "install" directory and build with intern libraries of blender source. But there must be more complications then that.<br>
<br>Further, I think most of possible reviewers are working on 2.50. If there is not further 2.4x version comming I might be able to port the node to 2.5 before its release. <br><br>Also, didn't get a lot of feedback about the interface but I was thinking in separating the node in:<br>
-one node for matte pulling<br>-merging my despill with the already existing one<br>-a Lift/Gamma/Gain + Hue/Saturation/Value color correction node<br>-a "lightmap" node for "spilling" the foregorund with "background light" <br>
-a edge blending blur node<br><br>So we can do a greenscreen with around 6 nodes and without mixing the noodles for changing parameters (or redundant parameters) whille keeping flexibility.<br><br>But as I do not really know if my code is "good" and this will change existing nodes of blender, maybe I will wait.<br>
<br>I will look into the color correction bug in the sequencer also, but this will change the resulting render of previous file. Is this OK?<br><br>Thanks<br><br>xavier<br><br><br><div class="gmail_quote">2008/12/8 patrick <span dir="ltr"><<a rel="nofollow" href="mailto:patrick@11h11.com" target="_blank">patrick@11h11.com</a>></span><br>

<br>
here's a linux build with the new composite node : keyer.<br>

<br>
<br>
Hello,<br>
<br>
I am new here and develloped a new node.<br>
I placed the patch in the tracker (#18012)<br>
<a rel="nofollow" href="https://projects.blender.org/tracker/index.php?func=detail&aid=18012&group_id=9&atid=127" target="_blank">https://projects.blender.org/tracker/index.php?func=detail&aid=18012&group_id=9&atid=127</a><br>
<br>
and some documentation here:<br>
<a rel="nofollow" href="http://wiki.blender.org/index.php/User_talk:Xat" target="_blank">http://wiki.blender.org/index.php/User_talk:Xat</a><br>
<br>
Can you, please, tell me if there is any chance for this to go to trunk. Of<br>
course I am dispo to work on this if the code don't meet your requirement.<br>
<br>
Thanks,<br>
<br>
xavier<br>
