A set of nodes for rendering a 3D model using a set of camera parameters based on at least a threshold error value may be selected. Each node corresponds to a bundle of data for rendering a geographic area at a particular resolution and the camera parameters including a point of view for rendering the 3D model. For a given node of the set of nodes, a smallest circle of confusion within a bounding box of the geographic area of the given node may be determined using the set of camera parameters closest to a particular parameter of the set of camera parameters. A diameter of the smallest circle of confusion is compared to the threshold error value. Based on this comparison, the threshold error value is adjusted. The adjusted threshold error value is used to select a new node to replace the given node in the set of nodes.
