摘要： The disclosure notably relates to a computer-implemented method for predicting vascular behavior of a patient, in particular a hemodynamic behavior. The method comprises providing a vascular model of a circulatory system, one or more measurements of the vascular behavior of the patient, and a surrogate model comprising an artificial neural network. The vascular model represents a general vascular behavior and comprises a plurality of physiological parameters. The surrogate model is configured to predict a simulation of a vascular behavior from the physiological parameters. The method further comprises calibrating the vascular model using the surrogate model and based on the one or more measurements; and predicting the vascular behavior of the patient using the calibrated vascular model.

摘要： A computer-implemented method for designing a virtual garment or upholstery (G) in a three-dimensional scene comprising the steps of:
a) providing a three-dimensional avatar (AV) in the three-dimensional scene;
b) providing at least one pattern (P) of said virtual garment or upholstery in the three-dimensional scene;
c) determining a distance field from a surface of the avatar;
d) positioning the pattern relative to the avatar by keeping a fixed orientation with respect to said distance field; and
e) assembling the positioned pattern or patterns around the avatar to form said virtual garment or upholstery, and draping it onto the avatar.
A computer program product, non-volatile computer-readable data-storage medium and Computer Aided Design system for carrying out such a method.
Application of the method to the manufacturing of a garment or upholstery.
