Abstract: Methods and systems for rendering a three-dimensional (3D) data model of an object are provided. An example method may include receiving information associated with a first 3D data model and a second 3D data model of an object. The method may also include rendering a first set of images of the first 3D data model, and rendering a second set of images of the second 3D data model. The method may also include comparing respective images of the first set of images to images of the second set of images to determine a plurality of image difference scores between the respective images of the first set of images and the images of the second set of images. The method may also include determining an object difference score based on the determined plurality of image difference scores.

Abstract: Methods and apparatus for aligning objects are provided. A computing device can receive first and second object representations that are respectively associated with first and second surface representations. The computing device can apply an object transformation to the respective first and second object representations to modify geometric features of the respective first and second object representations based on one or more values of one or more characteristics of the respective first and second surface representation. The computing device can align the first object representation and the second object representation using an alignment of the transformed first object representation and the transformed second object representation. The computing device can provide an output based on the aligned first object representation and second object representation.

Abstract: Methods and systems for texturing of three-dimensional (3D) object data models are provided. An example method may include receiving information indicating a geometry of an object receiving a plurality of images of the object. The method may also include assigning images of the plurality of images that have a resolution above a threshold to a plurality of polygons that approximate the geometric surface of the object. The method may also include determining adjacent polygons that are assigned to different images of the plurality of images so as to identify boundaries of images and minimizing such boundaries. The method may also include determining a mismatch factor for boundaries of the modified boundaries of images and reassigning images in boundaries having a mismatch factor above a threshold so as to reduce a gradient variation between the images in the modified boundaries.
