title = "SpiCa: Stereoscopic Effect Design with 3D Pottery Wheel-type Transparent Canvas",
abstract = "Flow effects such as flames, smoke, and liquids play an important role in activating illustrations, but drawing these effects requires artistic expertise as well as a great deal of effort. In this paper, we propose a method for adding stereoscopic flow effects to character illustrations using various shapes of 3D pottery wheel-type transparent canvases. One approach to designing a flow effect to decorate a character relies on simple curved geometry to beautify its flow in an organized composition. We extend this approach to present a drawing system-SpiCa (spinning canvas), which enables users to use transparent surface of revolution canvases to design 3D flow effects. User evaluations showed that users were able to create such effects more easily and effectively and reduce their workload with SpiCa in comparison with an existing 2D illustration tool. ",

note = "Funding Information: However, the conditions and scale of this evaluation did not result in a significant improvement in the efficiency of the design of flow effects. For more efficient creation of such effects, we need to improve the usability of SpiCa as a drawing tool. The comments in Supplement S–3 call for improved customizability and performance for drawing details. Other future work includes extending the effect transformation and enriching composite of the style, perspective, and lighting with input images. At present, we are developing SpiCa as a system for static illustration, but we plan to extend it to a flow effect animation system by employing a method that combines sketch input and physical simulation.
