Three-dimensional bio-model skeleton automatic binding system, method and device, and computer program product

Abstract

Embodiments of the invention disclose a three-dimensional bio-model skeleton automatic binding system, method and device, and a computer program product. The method comprises the steps of obtaining data of a pre-built three-dimensional bio-model, and calculating the volume of the model by utilizing the obtained data and matching the positions of skeletons; binding the located skeletons and corresponding joints in the model; and calculating voxel information of the skeletons and model skin, and according to an association relationship between the voxel information, allocating skin weights, thereby finishing skin. For the problem of consumption of a large amount of time for binding a large amount of bio-models due to an existing technology for manually binding the skeletons and the joints ofthe three-dimensional bio-model, it is proposed that automatic locating of the skeletons is realized based on the volume of the model and a topological structure, automatic joint binding is realized,and the bound bio-model has basic animation K frame demands, so that the skeleton binding time of the bio-model is greatly shortened and efficient skeleton and joint binding can be performed for thelarge amount of the bio-models.

Description

technical field [0001] The invention relates to the technical field of computer images, in particular to a system, method, device and computer program product for automatic binding of three-dimensional biological model bones. Background technique [0002] The three-dimensional biological model includes bones and skin, and the movement of the biological model must involve the simultaneous movement of the bones and skin. Therefore, it is first necessary to bind and position the bones of the biological model in order to control its movement later. When a large number of biological models are required for 3D animation or special effects production, the traditional binding technology will consume a lot of manpower. Each biological model needs to manually match the bone position and manually set the binding joints. The binding of an ordinary quadruped will consume a lot time. [0003] Therefore, prior art still needs further development. Contents of the invention [0004] In v...
