Abstract: Various approaches discussed herein enable providing accurate 3D visualizations of an object at arbitrary viewpoints by identifying portions of geometric mesh data (e.g., triangles of a triangular mesh) associated with the object and determining instances of image data (e.g., high-resolution image data) in which the portions of geometric mesh data are viewable, the instances captured at various viewpoints surrounding the object. The instances of image data are modified based on mappings between the various viewpoints, such that features of a texture generated for a pixel location of the 3D visualization are based on accurate pixel locations of the modified instances of image data, offering a clear rendering of the object without misalignment artifacts.
