Implementation of Animation Character Action Design and Data Mining Technology Based on CAD Data

In the traditional animation character design process, designers need to spend a lot of time and effort on handcrafting. Now, with professional 3D design software, designers can quickly create basic models and then make detailed adjustments, greatly shortening the production cycle. Thanks to the precise control of computer technology, designers can modify character models at the micro level, achieving precise adjustments in facial expressions, body proportions, and hair details. How to endow characters with vivid and realistic actions based on these static computer-aided design (CAD) data is a challenging problem. This article utilizes precise 3D models provided by CAD data, combined with data mining (DM) technology, to extract motion features, making character action design more efficient. The results show that compared to the SVM algorithm, our algorithm exhibits significant advantages in modeling error and modeling accuracy. They are indicating its stronger ability to fit data and more accurate prediction results. In addition, in terms of response speed, the algorithm presented in this article also exhibits fast characteristics, which makes it more competitive in processing large-scale datasets or applications that require real-time feedback. © 2024, CAD Solutions, LLC.
