Abstract
Methods, systems, and devices for generating textured 3D models are provided. The present disclosure describes methods, systems, and devices for combining multiple images onto a 3D model. In some instances, the textures of the images are applied to the 3D model dynamically so that the textured 3D model is viewable from different viewpoints in real time on a display. The present disclosure also describes methods, systems, and devices for selecting the images and, in particular, the portions of the selected images to map to defined portions of the 3D model. In addition, the present disclosure describes how to adjust the images themselves to remove the effects of directional lighting. Some aspects of the present disclosure are particularly useful in the context of a 3D modeling of dental preparations. In some instances, a 3D digitizer is used to produce 3D models of dental preparations that are rendered on a display in real time and are fully 3D dimensional, while accurately depicting the surface textures of the item(s) being digitized.
