Digital character rigging is an important technology to improve animation vividness, and there are many kinds of complex ways of rigging system. To move naturally, the fish are tested for movement. Because 2,4 family role information although some, but the study of fish (0 family) action information is not much. As the diversity and complexity of fish production increases, inefficient time and capital are required. How to build a fish-like skeleton system depends on how to build an efficient and agile rigging program. The aim of this study is to compare the Advanced Skeleton-based animation process with Maya Rig, which can solve the high time-cost rigging problem, and to explore the best automatic plug-in based on the advantages of Advanced Skeleton, broadening the research scope of fish animation.

This paper addresses the task of transferring facial blendshape models to an arbitrary target face. Blendshape is a common method for the facial rig; however, production of blendshape rig is a time-consuming process in the current facial animation pipeline. We propose automatic blendshape facial rigging based on our blendshape transfer method. Our method computes the difference between source and target facial model and then transfers the source blendshape to the target face based on a deformation transfer algorithm. Our automatic method provides efficient production of a controllable digital human face; the results can be applied to various applications such as games, VR chating, and AI agent services.

To the purpose of keeping net mouth of seine with bag open in the seining operation a novel method was devised and tested with model gear that double textile strips were fixed at both side edges of bag net mouth as sheering devices. The angles of attack of inner and outer strips were the 40 in degrees by adjusting rigging. In seining operation current that flowed between the double strips and generated side force on the strips sheered and opened the net mouth automatically. This paper described dynamic characteristics of the sheering strips and its automatic opening function of net mouth.

In computer graphics and computer vision research and its applications, various representations of 3D objects, such as point clouds, voxels, or triangular meshes, are used depending on the purpose. The need for animating characters using these representations is also growing. In a typical animation pipeline called skeletal animation, "skinning weight painting" is required to determine how joints influence a vertex on the character's skin. In this paper, we introduce a neural network for automatically performing skinning weight painting for characters represented in various formats. We utilize signed distance fields (SDF) to handle different representations and employ graph neural networks and multi-layer perceptrons to predict the skinning weights for a given point.
