Modular Motion Tracking Framework

thingiverse

Reconfigurable framework for creating stand-in props when match-moving 3D objects into video footage is available. To access this feature, some countersunk 4G 10mm or up to 15mm screws are needed, which can be found at any hardware store. In addition, brightly colored paint or plastics should be used to create high-contrast ball ends. The rod enables fast connection at right angles to other rods via their screw hole ends and ball arms can be attached from any of the holes. Balls can be moved around without needing to unscrew anything via a simple quick bayonet connector, making it possible to swap colors around or put different sized balls on the arms without drama. The rods can also be screwed onto other surfaces to mount the balls onto costumes or existing objects. The balls have a flattened surface on one side and can sit happily on flat surfaces to provide extra camera tracking objects in a scene. These objects were designed for working with Blender's tracking tools but should be useful in other VFX software and could be used with blob tracking in Processing or other art coding tools to quickly make props with real-time 9-dof absolute positional tracking. More objects will be added as needed. Feel free to request any. **Instructions:** Print at 0.2mm layer height using brightly colored plastics or neon spray paint on the balls and plain (black, white) plastics/paint on the body. A matte finish may need to be applied if plastic comes out shiny because moving reflections can complicate tracking.
