Transforming a three-dimensional virtual model to a manipulatable format
A three-dimensional (3D) content refactoring system may maintain the external look and behavior of a donor model, while changing the underlying data to conform the donor model to content standards of a modeling application. The 3D content refactoring system may make the donor model adhere to the content standards by mapping the donor model to a target model that is already formatted for the modeling application.
1. A system to refactor content corresponding to three-dimensional (3D) assets, the system comprising:
a processor and non-transitory memory to:
identify, based on a similarity between a first shape of a target model in adherence with a target 3D modeling standard and a second shape of a donor model not in adherence with the target 3D modeling standard, the target model in adherence with the target 3D modeling standard;
generate, based on a first landmark that indicates a first location at the donor model and a second landmark that indicates a second location at the target model and corresponding to the first location, a landmark map that correlates the first landmark with the second landmark;
translate, to match the first landmark and vertices surrounding the first landmark, a vertex at the second location and corresponding to the target model;
generate, based on the landmark map and based on positional differences between vertices of the target model and the second shape, a blendshape;
deform, based on the blendshape, the target model into a modified target model with the second shape and in adherence with the target 3D modeling standard;
modify, based on a determination that the donor model is incompatible with a target 3D modeling application corresponding to the target 3D modeling standard, an aspect of the target model to adhere with the target 3D modeling application;
generate, based on the target model, a dummy mesh having the second landmark; and
translate, to match the first landmark and vertices surrounding the first landmark, a vertex of the dummy mesh at the second location, the blendshape corresponding to offsets of the dummy mesh.

compare the first shape of a compliant model with the second shape; and

refine a shape corresponding to the target model to more precisely match the second shape.

cut the dummy mesh in half;

mirror the half of the dummy mesh to generate the blendshape.
7. A method to refactor content corresponding to three-dimensional (3D) assets, the method comprising:
