Patent number: 11847738Abstract: One embodiment of the invention disclosed herein provides techniques for voxelizing a mesh representation associated with a three-dimensional model to generate a volumetric model. A model filling engine associated with a voxelization system identifies a first voxel included in a voxel grid array that intersects with the mesh representation. The model filling engine selects a second voxel at an exterior boundary of the voxel grid array that is not identified as a boundary voxel. The model filling engine marks the second voxel as an exterior voxel. The model filling engine marks all unmarked voxels that are adjacent to the second voxel as exterior voxels. The model filling engine marks all remaining voxels as interior voxels. A model finishing engine associated with the voxelization system generates a volumetric model based at least in part on the first voxel.Type: GrantFiled: August 22, 2018Date of Patent: December 19, 2023Assignee: AUTODESK, INC.Inventors: Martin Bisson, Olivier Dionne, Martin De Lasa

Patent number: 10489956Abstract: One embodiment of the invention disclosed herein provides techniques for transferring attributes from a source animated character to a target character. A character attribute transfer system identifies a first set of markers corresponding to the source animated character. The character attribute transfer system identifies a second set of markers corresponding to the target character. The character attribute transfer system generates a geometric correspondence between the source animated character and the target character based on the first set of markers and the second set of markers independent of differences in geometry between the source animated character and the target character. The character attribute transfer system transfers a first attribute from the source animated character to the target character based on the geometric correspondence.Type: GrantFiled: July 21, 2016Date of Patent: November 26, 2019Assignee: AUTODESK, INC.Inventors: Olivier Dionne, Martin De Lasa, Srinivasan Ramachandran, Sahel Fallhdoust, Eric Paquette, Donya Ghafourzadeh, Quentin Avril

Patent number: 9836879Abstract: A computer-implemented method for computing skinning weights. The method includes traversing one or more paths from a first voxel included in a voxelization associated with a three-dimensional model to a second voxel included in the voxelization. The first voxel intersects a first influence included in the three-dimensional model. The second voxel intersects a target vertex associated with the three-dimensional model. The voxelization includes a set of interior voxels. The first voxel and the second voxel are included in the set of interior voxels. The method also includes identifying a first path included in the one or more paths that is associated with a first distance value related to the second voxel that indicates that the first path represents the shortest distance between the first voxel and the second voxel. The method further includes assigning a skinning weight to the target vertex based on the first distance value.Type: GrantFiled: April 11, 2014Date of Patent: December 5, 2017Assignee: AUTODESK, INC.Inventors: Olivier Dionne, Martin De Lasa

Patent number: 6484068Abstract: A robot apparatus that is able to perform jumping. In a leg structure 110 of the robot apparatus, connecting bars 113, 114 and pivots 112a to 112d constitute a four-point link mechanism. A rod 117 is inserted into an opening formed in the distal end of a leg part 116. A coil spring 118 as an elastic member is provided between one end of the rod 117 and the distal end of the leg part 116. A bar member 120 is connected and secured to a preset point of a connecting member 115 as a knee joint. The coil spring 118 is extended/contracted by the stretching/contraction of the connecting member 115. By the operation of the four-point link mechanism, the trajectory of the distal end of the leg part is linear. The coil spring 118 is mounted at a position such that the distance between a driving shaft 101 and the distal end of the bar member 120 has a substantially linear relationship with respect to the force virtually operating between a driving shaft 101 and the distal end of the bar member 120.Type: GrantFiled: September 21, 2001Date of Patent: November 19, 2002Assignees: Sony Corporation, Boston Dynamics IncInventors: Takashi Yamamoto, Martin de Lasa, Shervin Talebinejad, Darrin Jewell, Robert Playter, Marc Raibert
