Virtual reality presentation of layers of clothing on avatars

A non-transitory computer storage medium storing instructions configured to instruct a computer device to perform a method implemented in a three-dimensional virtual reality world, the method comprising:

• storing, for each generic cloth model in a plurality of cloth models acquired for an avatar model independently of others of the plurality of cloth models:
• a respective fitted cloth model;
• and
• a respective collapsed cloth model;
• and
• wherein the fitted cloth model is generated from the generic cloth model by:
• scaling uniformly the generic cloth model along a plurality of dimensions to match an overall size of the avatar model to generate a uniformly scaled generic cloth model;
• identifying at least one boundary edge of cloth represented by the uniformly scaled generic cloth model that has a dimension mismatch between the cloth and an avatar represented by the avatar model;
• determining a dimension change of the boundary edge of cloth relative to the avatar to reduce the dimension mismatch between the cloth and the avatar;
• stretching or shrinking the boundary edge of the cloth according to the dimension change to cause non-uniform stretching or shrinking of the uniformly scaled generic cloth model, resulted from reduction from the stretching or shrinking according to the dimension change at the boundary edge of the cloth to diminished stretching or shrinking in areas away from the boundary edge of cloth;
• generating a deformed cloth model from the stretching or shrinking the boundary edge of the cloth according to the dimension change;
• and
• performing a physical simulation of fitting the deformed cloth model on the avatar model to generate the fitted cloth model worn on the avatar;
• in response to a user request to apply the plurality of cloth models on the avatar models according to a sequence of layers of clothing from inside to outside,
• painting textures of collapsed cloth models of inner layers of the plurality of cloth models on the avatar model according to the sequence to generate an avatar model wearing the inner layers;
• and
• combining a fitted cloth model generated from an outermost layer of the plurality of cloth models on the avatar model and the avatar model wearing the inner layers to generate an avatar model wearing the plurality of cloth models according to the sequence from inside to outside.

A computing system to implement a three-dimensional virtual reality world, the system comprising:

• a server system;
• and
• a data storage device storing:
• a three-dimensional model of the virtual reality world;
• avatar models representing residences of the virtual reality world;
• and
• cloth models defining shapes and appearances of clothing;
• wherein for each of a plurality of cloth models acquired by a user for an avatar model, the server system generates and stores:
• a respective fitted cloth model based on a physical simulation of fitting the respective fitted cloth model on the avatar model independently of others of the plurality of cloth models, wherein the fitted cloth model is generated by:
• scaling uniformly a generic cloth model along a plurality of dimensions to match an overall size of an avatar model to generate a uniformly scaled generic cloth model;
• identifying at least one boundary edge of cloth represented by the uniformly scaled generic cloth model that has a dimension mismatch between the cloth and an avatar represented by the avatar model;
• determining a dimension change of the boundary edge of cloth relative to the avatar to reduce the dimension mismatch between the uniformly scaled generic cloth model and the avatar;
• stretching or shrinking the boundary edge of the uniformly scaled generic cloth model according to the dimension change to cause non-uniform stretching or shrinking of the uniformly scaled generic cloth model, resulted from reduction from the stretching or shrinking according to the dimension change at the boundary edge of the uniformly scaled generic cloth model to diminished stretching or shrinking in areas away from the boundary edge of the uniformly scaled generic cloth model;
• and
• generating a deformed cloth model from the stretching or shrinking the boundary edge of the uniformly scaled generic cloth model according to the dimension change;
• and
• a respective collapsed cloth model having a shape that is the same as to a shape of at least a portion of the avatar on which the collapsed cloth model is to be worn;
• and
• wherein in response to a user request to apply the plurality of cloth models on the avatar models according to a sequence from inside to outside, the server system:
• paints textures of collapsed cloth models of inner layers of the plurality of cloth models on the avatar model according to the sequence to generate an avatar model wearing the inner layers;
• and
• combines a fitted cloth model generated from an outermost layer of the plurality of cloth models on the avatar model and the avatar model wearing the inner layers to generate an avatar model wearing the plurality of cloth models according to the sequence from inside to outside.
