3D Animation Simulation Based on Computer Virtual Simulation Technology

3D animation involves computer VST (virtual simulation technology). As one of the important technologies of 3D animation, this technology can not only enhance the sensory effect of 3D animation but also has great significance for the successful construction of virtual environment. In this paper, character modeling and character animation generation are deeply studied. Based on the skeletal animation algorithm, the source files of 3D human skeletal animation are created in the modeling software, which mainly includes creating meshes, adding bones, skinning and editing envelopes. Then, the real motion data are obtained by motion capture technology, and the data are optimized and redirected to drive the 3D character motion. The research results show that the effect of skeleton animation is still good, and some basic actions have been completed. The improvement of this place is to add artificial intelligence elements, which makes the animation more natural and real. The research on action simulation technology of virtual characters based on skeletal animation algorithm has important engineering application value.
