Abstract
Lenticular prints are a popular medium for producing automultiscopic glasses-free 3D images. The light field emitted by such prints has a fixed spatial and angular resolution. We increase both perceived angular and spatial resolution by modifying the lenslet array to better match the content of a given light field. Our optimization algorithm analyzes the input light field and computes an optimal lenslet size, shape, and arrangement that best matches the input light field given a set of output parameters. The resulting emitted light field shows higher detail and smoother motion parallax compared to fixed-size lens arrays. We demonstrate our technique using rendered simulations and by 3D printing lens arrays, and we validate our approach in simulation with a user study.

Resources - Light Fields
Resources - Geometry
  • All geometry is in mm scale.
    All geometries (except the 'Lenticular lens sheets') require a bi-material printer. In our case, we used a Stratasys Objet500 Connex printer, with VeroBlack and VeroClear materials. Feel free to contact me if you're attempting to print these, especially the bigger pieces!
