1. A computer-implemented method for repairing a set of defects associated with a three-dimensional (3D) model, the method comprising: rendering a first image that represents the 3D model from a first viewing position; receiving a first threshold associated with a first defect parameter via a first user interface element included in a graphical user interface (GUI); receiving a second threshold associated with the second defect parameter via the second user interface element included in the GUI; determining a set of defects included in the 3D model based on the first threshold associated with the first defect parameter and the second threshold associated with the second defect parameter, wherein each defect included in the set of defects exceeds the first threshold and the second threshold; generating within the first image a set of defect indicators, wherein each defect indicator is associated with a different defect in the set of defects and resides at a different location within the first image corresponding to a location of the associated defect within the 3D model; automatically selecting a different defect viewing position associated with each defect in the set of defects based on the location of the defect within the 3D model, wherein each defect viewing position corresponds to a different angle from which to view the 3D model; rendering a different thumbnail image for each defect in the set of defects based on the associated defect viewing positions, wherein the thumbnail image associated with a particular defect shows the particular defect from a defect viewing position associated with the particular defect; and causing the GUI to display the first image and a filmstrip that includes the thumbnail images to the end-user.
