Methods and systems for providing a preloader animation for image viewers is provided. An example method includes receiving an image of an object, determining an edge gradient value for pixels of the image, and selecting pixels representative of the object that have a respective edge gradient value above a threshold. The example method also includes determining a model of the object including an approximate outline of the object and structures internal to the outline that are oriented based on the selected pixels being coupling points between the structures, and providing instructions to display the model in an incremental manner so as to render given structures of the model over time.
