Abstract
In 3D games, dynamically simulating the interaction between plants and the outside world can enhance the dynamic feel of the scene. However, due to the complexity and diversity of plant structure quantity, as well as the high demand for real-time animation, this real-time dynamic simulation is still a field worth further research and development. In order to analyze the dynamic simulation effect of interaction between characters and small plants in game scenes, this paper conducted algorithm design and experiments using Delta3D as an experimental platform and achieved the research goal, enabling virtual characters in 3D games to generate certain interactive animations with small plants in the scene. And this study makes small plants no longer static or only produce rigid animations, increasing the dynamic feel of the scene. In the process of algorithm design and experiment, this paper adds the principle of skeletal animation in character animation to small plants as the deformation mode of plants and uses the rotation and movement of bones to drive the deformation animation of various leaves. On the basis of this basic algorithm, this paper also conducted experiments on two types of grass and two types of characters, wind and rain, to meet the basic application requirements of 3D game animation.
