Systems and methods for lod generation for clothing objects

A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors, causes a computing device to generate a simplified mesh, by performing operations comprising:

• receiving an input mesh, wherein the input mesh is a polygonal mesh, wherein the input mesh is associated with an outer bound mesh and an inner bound mesh, wherein each vertex of the input mesh is located inside the outer bound mesh and outside the inner bound mesh;
• performing one or more mesh simplification operations on the input mesh to generate a level-of-detail (LOD) mesh corresponding to the input mesh;
• for a first vertex of the LOD mesh, determining that the first vertex is located outside the outer bound mesh or inside the inner bound mesh;
• determining a bound vector for the first vertex that binds the first vertex to the outer bound mesh when the first vertex is located outside the outer bound mesh or binds the first vertex to the inner bound mesh when the first vertex is located inside the inner bound mesh;
• and
• generating an updated LOD mesh based on moving the first vertex based on the bound vector, wherein the first vertex in the updated LOD mesh is located inside the outer bound mesh and outside the inner bound mesh.

A device for generating a simplified mesh, the device comprising:

• a memory storing instructions;
• and
• one or more processors configured to the execute the instructions to cause the device to:
• receive an input mesh, wherein the input mesh is a polygonal mesh, wherein the input mesh is associated with an outer bound mesh and an inner bound mesh, wherein each vertex of the input mesh is located inside the outer bound mesh and outside the inner bound mesh;
• perform one or more mesh simplification operations on the input mesh to generate a level-of-detail (LOD) mesh corresponding to the input mesh;
• for a first vertex of the LOD mesh, determine that the first vertex is located outside the outer bound mesh or inside the inner bound mesh;
