Had some footage of a basement car park.. decided to try some camera tracking late last night..
Camera tracking is where you get your cg camera to mimic the movement of the camera that shot the video footage.. thus allowing you to composite 3d geometry into the scene, such that its position and movement matches with the objects in the video(in the Background Plate)..
Havn't yet figured out how to render the final footage using the nodes to composite the background plate with the 3d geometry.. but here a screen grab of what i managed to do last night
I followed these detailed tutorials by cgboorman on youtube:
hope he does a follow up on compositing soon
