Collision and self-collision processing method, system and equipment in clothes simulation and medium

The invention discloses a collision and self-collision processing method, system and device in clothes simulation and a medium, and relates to the field of computer graphics, and the method comprises the steps: obtaining particle position information, normal vector information and adjacency information of a current frame; determining an axis alignment cuboid bounding box of the current frame, and segmenting the bounding box into a plurality of three-dimensional voxels with the same size according to set granularity; constructing a spatial distance field of the current frame; determining collision potential energy of each clothing material point of the current frame according to the clothing material point position information of the current frame and the spatial distance field; determining a mass point-voxel index of the current frame; according to the adjacency information and the mass point-voxel index of the current frame, self-collision detection is carried out on each clothing material point of the curre
