The goal of the research is to improve the efficiency of creating animations by combining 2D cell-animation and 3D animation in one tool. The researchers developed a plug-in for 3D tools that allows for intuitive timing of cell-animation and movement of 3D objects. By applying this system, they found that it is possible to enhance the production efficiency of animations by saving clips with required images for each frame, rather than sequences. This approach aims to address the challenge of low production efficiency when combining different animation methods, ultimately leading to more successful creation of diverse animation content.
