I am using Blender to track the camera movement data, then exporting the data and reading it in vvvv to create real-time animations matching the background video footage. Already tried with voodoo but the tracking data wasn’t so effective, quick and precise as the one in blender 2.8.
So, since I have not found much info online on how export simple camera data from Blender, I tried some exporters and found the one for Nuke (.chan) could work.
This Nuke exporter writes the following columns per each camera animation frame:
frame location.x location.y location.z rotation_euler.x rotation_euler.y rotation_euler.z angle_y
I have tried to build a template patch in vvvv (here attached the whole package) with tracked footage and 3D placeholders. My limited knowledge in matrix transformations do not let me proceed. I copied some nodes from the voodoo patch but it did not work. Something wrong with the rotations.
