Abstract: A computer-implemented method and system automatically adjusts the size of a rigid body model. The method and system construct a two-dimensional model or a three-dimensional model, where the model has one or more rigid bodies. The rigid bodies are converted into geometric primitives that represent a respective rigid body and enable the respective rigid body to resize. One or more of the primitives are constrained to one another. A solver process changes a size of at least one geometric primitive and a rigid body simulation process uses the resized primitive(s) as input.

Abstract: A computer-implemented method for designing a 3D modeled object representing a real object comprises providing a 3D mesh representing the real object, a texturing image and a mapping between the vertices of the 3D mesh and pixels of the texturing image; then maximizing a probability P(L(V)) of the form: P  ( L  ( V ) ) = 1 Z  exp  ( - ∑ i = 1 n   ϕ i ′  ( L  ( v i ) ) - ∑ f ∈ ℱ   ψ f ′  ( { L  ( v i ) } i ∈ f ) ) . Maximizing is performed with a predetermined discrete Markov Random Field optimization scheme viewing the 3D mesh and the pixel shifts associated to the texture coordinates of the vertices of the 3D mesh as a Markov Random Field of energy −log(P(L(V)))−log(Z). The method then comprises texturing the 3D mesh according to the texturing image, to the mapping, and to the result of the maximizing.This provides an improved solution for designing a 3D modeled object a real object.

Abstract: A system for generating texture maps for 3D models of real-world objects includes a camera and reflective surfaces in the field of view of the camera. The reflective surfaces are positioned to reflect one or more reflected views of a target object to the camera. The camera captures a direct image of the target object and reflected images from the reflective surfaces. An image processor device separates the reflected views/images from the direct image of the target object in the captured image by detecting distortion in the reflected views. The image processor reduces distortion in the reflected views, and generates a texture map based on 3D space characteristics of the target object and on the reflected views. Reducing distortion in the reflected views may include scaling the reflected views to correspond to a size of the target object in the camera field of view.

Abstract: Computer simulation generates improved 3D images of human movement involving an object associated with the human character. A set of axes in 3 dimensional space is originally defined for tracking orientation of the human character in a 3D image. This set of axes is subsequently automatically applied to and used for object(s) carried by the human character. The object is displayed at a constant (same, unchanged) orientation while the human character is illustrated moving in certain ways in succeeding 3D images.
