Mocap Baseball Swing Figurines

thingiverse

I modeled a set of three figurines from motion capture data of a baseball swing, and I collaborated with ZenoLink to do it! These figurines were created with an OpenSCAD script that placed spheres at the coordinates of each joint, then connected nodes using the hull command to form the limbs and torso. The sweep of the bat in the third model was formed by joining consecutive pairs of bat positions into a single shape. I'm satisfied with how well this static representation captures the motion of an object. My next project might involve swapping out the simple stick figures for other character models rigged with similar data. Here are the print details: The figurines were printed on my Printrbot Simple, which has a wood body and uses black PLA filament that's hard to photograph. The print settings included 0.3 mm layers, 3 perimeters, 5% infill, and rectilinear patterns in all directions. I also experimented with different retraction and temperature settings to minimize overhang curling.
