I have a an animated sphere thats been translated in x axis.<BR />What I would love to do is basically have&nbsp; the previous frame geo available to do some maths...(eg subtracting positions to get the direction vector)<BR />I am kinda not able to get it through the feedback ports... I guess they work when the geo is deformed within the compound??(I might be wrong here..)<BR /><BR />Any help would be super useful.<BR />Thanks a lot <span class="lia-unicode-emoji" title=":slightly_smiling_face:">🙂</span></P> Sat, 10 Oct 2020 09:12:50 GMT https://forums.autodesk.com/t5/bifrost-forum/get-previous-frame-geometry/m-p/9795216#M5491 Anonymous 2020-10-10T09:12:50Z https://forums.autodesk.com/t5/bifrost-forum/get-previous-frame-geometry/m-p/9795571#M5492 <P>Here is the simplest way to gest previous frame data.<BR /><BR /><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="feedback_port_previous_frame1.jpg" style="width: 999px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/829761i2FEF9F8A8396A66C/image-size/large?v=v2&amp;px=999" role="button" title="feedback_port_previous_frame1.jpg" alt="feedback_port_previous_frame1.jpg" /></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="feedback_port_previous_frame2.jpg" style="width: 999px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/829760i39585F3F693A384A/image-size/large?v=v2&amp;px=999" role="button" title="feedback_port_previous_frame2.jpg" alt="feedback_port_previous_frame2.jpg" /></span></P> Sat, 10 Oct 2020 17:04:42 GMT https://forums.autodesk.com/t5/bifrost-forum/get-previous-frame-geometry/m-p/9795571#M5492 mjcg91 2020-10-10T17:04:42Z https://forums.autodesk.com/t5/bifrost-forum/get-previous-frame-geometry/m-p/14100528#M9694 <P>Im Very confused how do i get a compound node to do that?</P> Wed, 22 Apr 2026 02:21:35 GMT https://forums.autodesk.com/t5/bifrost-forum/get-previous-frame-geometry/m-p/14100528#M9694 jacob_levinson 2026-04-22T02:21:35Z https://forums.autodesk.com/t5/bifrost-forum/get-previous-frame-geometry/m-p/14101420#M9697 <P>its just a solver (feedback loop), so you can use the simulation example node.&nbsp;</P><P>or you can create a compound, then you right click on the port and set the feedback port.&nbsp;</P><P>Like this</P><P>&nbsp;</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="maya_VmwrcB1MCb.gif" style="width: 400px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1635168iB4C6FBB72F86B46E/image-size/medium?v=v2&amp;px=400" role="button" title="maya_VmwrcB1MCb.gif" alt="maya_VmwrcB1MCb.gif" /></span></P><P> </P> Wed, 22 Apr 2026 15:41:57 GMT https://forums.autodesk.com/t5/bifrost-forum/get-previous-frame-geometry/m-p/14101420#M9697 sepu6 2026-04-22T15:41:57Z
