RefCube or RefTrack, your gizmo for aligning your 3D with HDRI and backplates, or video and film.
What is this for?
For proper integration of 3D models into photography or video/film, we need as much information of the location and the camera(s) used during a shoot.
The brand and model of the camera will give us information on the dimensions of the backplate, the lens that was used will gives us the focal data.
We write down additional information on height, angle etc., so we recreate these values in 3D.
But we also we need some form of reference to ‘ground’ our 3D into the plate, later on in the process. This is were the RefCube and RefTrack come in.
The RefCube or RefTrack is a physical object with a known size in your frame and/or backplates, to help you to align the 3D camera to the one from the real world.

Who made it?
The RefCube and Reftrack are the brainchild of Rob Wuijster and Bob Groothuis. Rob has been doing ‘stuff in 3D’ for quite some time now, and is a enthousiastic HDRI photographer as well. Just for fun, or on set.
Bob Groothuis is well known for his Dutch Skies 360 HDRI panoramas, that are used in games, commercials and movies. We had a personal need for something like the RefCube or ReftTrack, but found nothing. So we decided to build our own.
Who are using The RefCube of RefTrack?
HDRI photographers that want to deliver complete (sIBL) sets of HDRI lighting, backplates and scale references. Post-production companies that want to have a reference model on set for scale or tracking purposes. So this could be used on set when shooting commercials, indy movies, movies, tv shows, and more.
Some example images
Note 1: The Kurhaus HDRI panorama used for the images above was created by Bob Groothuis and shot exclusively for the “3D Artist” magazine, issue 42.
Note 2: An earlier prototype + article that started the whole idea to website, and some additional free sIBL / HDRI sets shot at Protospace Fablab Utrecht can be found here.
The RefCube website is an initiative of Rowu Media.
