Immersive Virtual Reality-Based Interfaces for Character Animation

Abstract

Virtual Reality (VR) has increasingly attracted the attention of the computer animation community in search of more intuitive and effective alternatives to the current sophisticated user interfaces. Previous works in the literature already demonstrated the higher affordances offered by VR interaction, as well as the enhanced spatial understanding that arises thanks to the strong sense of immersion guaranteed by virtual environments. These factors have the potential to improve the animators' job, which is tremendously skillintensive and time-consuming. The present paper explores the opportunities provided by VR-based interfaces for the generation of 3D animations via armature deformation. To the best of the authors' knowledge, for the first time a tool is presented which allows users to manage a complete pipeline supporting the above animation method, by letting them execute key tasks such as rigging, skinning and posing within a wellknown animation suite using a customizable interface. Moreover, it is the first work to validate, in both objective and subjective terms, character animation performance in the above tasks and under realistic work conditions involving different user categories. In our experiments, task completion time was reduced by 26%, on average, while maintaining almost the same levels of accuracy and precision for both novice and experienced users.

[Retracted] Multivisual Animation Character 3D Model Design Method Based on VR Technology

“…e construction of multivisual animation character 3D models, combined with virtual reality and visual simulation technology, carries out multivisual animation character 3D model design. It can improve the visual display and dynamic analysis capabilities of animated characters [2].…”

“…It mainly analyzes the 3D graphics algorithm used in the three-dimensional geometric transformation of computer graphics and studies the basic texture technology, basic lighting model, and other image output processes used in the fragment processing stage. (2) Research the representation methods of three-dimensional objects and several methods and techniques for modeling solid objects, including polygons, splines, and parametric surfaces in boundary representation methods. Combined with the development needs of the subject, the principles of 3D animation rendering production software and 3D graphics modeling are studied, and the solid 3D model displayed in the virtual reality scene is designed and produced.…”

First Steps Towards Augmented Reality Interactive Electronic Music Production

“…New tools better connected to this new medium have to appear so that to be able to think for this medium, and not only adapt old practices, in line with the "Don't port" design principle already mentioned [1]. Furthermore, this lack of tools is surprising, since many VR/AR visual authoring tools already exist, some being already professionally used by animators in the 3D animation field [10]. About immersive music production tools, recent projects have emerged, such as the modular project called PatchXR [27], but more research has to be conducted.…”

Evaluating Consumer Interaction Interfaces for 3D Sketching in Virtual Reality

“…The software adopted for the experimental activity was developed starting from the VR tool presented in [12] as a Blender 2.79 [30] add-on. This tool was previously used in other research works like, e.g., [10,11], and [25].…”
