Patent ID: 11995771

Abstract:
Disclosed are various approaches for automatically assigning weights to vertices of a skin or mesh that control how said vertices in the 3D model move under the influence of skeletal rotation and translation. A computing device can receive a first model weightings matrix. Next, the computing device can include adjusting the number of rows in the first model weightings matrix to generate an adjusted model weightings matrix with a number of rows that matches an input number of rows for a machine-learning model, each row in the adjusted model weightings matrix representing a vertex of a mesh applied to a three-dimensional model. Then, the computing device can apply the machine learning model to the adjusted model weightings matrix, to generate an output polygonal mesh model weightings matrix. Subsequently, the computing device can generate a second polygonal mesh model weightings matrix by adjusting the number of rows of the machine learning model output weightings matrix to match the number of rows of the initial polygonal mesh model weightings matrix.
