Analyzing Interfaces and Workflows for Light Field Editing

“…Procedure: Twenty paid subjects (6 female, 14 male) took part in the experiment. This is consistent with the number of subjects typically used in other similar statistical user studies, which usually range between two and 30 [24], [26], [27], [33]. Each subject used each of the four interfaces for all tasks, in random order to avoid possible learning effects.…”

“…Overall, we make two main observations: First, the workflow is a constant iteration of acting upon the scene (drawing/erasing) and checking the results, which is common among artists working with other media too [33]. Our interfaces thus seem to offer a valid approach for the usual artist workflow to be applied to light fields.…”

“…b) Interfaces and workflows: Many different interfaces and workflows have recently been explored for a wide range of applications, including authoring of 3D models [20], freeform design of objects [21], drawing lines to depict shapes [22], facial animation [23], sketching 3D surfaces [24], lighting design [25], [26], material editing [27], [28], icon selection [29], style similarity [30], [31], or simulation of cloth [32], to name a few. Closer to our approach, Santoni et al [33] presented a statistical analysis of 3D digital sculpting. The authors analyzed users' behavior as they freely sculpted organic models to discover patterns in the data and trends in the workflows.…”

PAVEL: Decorative Patterns with Packed Volumetric Elements

“…• an overall method for decorating surfaces with packed volumetric elements supporting automatic and manual element decorations, and automatic removal of decoration overlap; to the best of our knowledge, this is the first packing method that works on 2-manifold directly; to the best of our knowledge, the decorated surfaces could not be created with any other automatic method and would require hours of manual work if sculpted manually [Santoni et al 2016]; • an efficient procedure to remove intersections and recover elements' volume that provides a visually effective, even if not physically exact, simulation of a plastic, volume-preserving deformation; • a practical demonstration of a decorative shell for an existing 3D object designed with PAVEL, decomposed into printable parts, manufactured and attached to the base shape.…”
