Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, facilitate creation and use of 3D models of objects with different material properties. In one aspect, a method includes specifying a continuous data format representation for a first property of an object and a discretized data format representation for a second property of the object, wherein the first property and the second property are different from each other; producing a 3D model of the object within a 3D space using the continuous and discretized data format representations, which overlap with each other in all three dimensions in at least a portion of the 3D space; and using at least one common access method into the 3D model of the object to obtain data from both the continuous and discretized data format representations, within the portion of the 3D space, to manufacture the object using one or more manufacturing processes.

Abstract: A novel method designs and analyzes composite parts including optimal manufacturing strategies. The invention analyzes part design including curvatures and other surface topology to formulate an optimal strategy for material layup, number of plies, initial orientation angle, and towpath steering vectors. The method computes an optimum starting point for each fiber path and a stagger offset for each successive fiber path to as to eliminate or minimize gaps and overlaps between adjacent plies. Intermediate surfaces are generated by a polynomial discretization method which generates large computational time savings and enhances blending of adjacent zones to control surface smoothness. The method further calculates a variable steering path for the layer taking into account material parameters and limitations such that plies originating in the same location have a variable orientation angle and follow any reference curve generated by the method to maximize strength and minimize weight of the component.

Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, facilitate creation and use of multi-material three dimensional models. In one aspect, a system includes one or more computer storage media having instructions stored thereon; and one or more data processing apparatus configured to execute the instructions to perform operations including (i) receiving input specifying different material properties of an object to be manufactured, (ii) generating from the input a three dimensional (3D) model of the object using overlapping volume representations of the different material properties of the object, wherein the overlapping volume representations employ different data formats and different resolutions, and (iii) storing the 3D model of the object for use in manufacturing the object.

Abstract: One embodiment of the present invention sets forth a technique for performing a draping simulation of a fabric that includes obtaining a problem definition that includes a fabric cell size, a spring constant ratio, and a three-dimensional (3D) surface. The technique also includes representing the fabric as a set of fabric cells with dimensions that adhere to the fabric cell size, modeling the fabric cells based on a set of side springs and a set of diagonal springs, and setting a first spring constant of the side springs and a second spring constant of the diagonal springs based on the spring constant ratio. The technique further includes propagating the fabric cells along the 3D surface according to the fabric cell size, the first spring constant, and the second spring constant to generate a result of the draping simulation.
