Abstract This paper addresses the problem of interactive visualization of multi‐resolution triangle meshes. Visible switching between different levels of detail is avoided by smoothly interpolating mesh geometry between different levels. The interpolation parameter is derived from the screen‐space geometric error of the affected mesh region instead of assigning a fixed time to the transition. The shortcomings of straightforward frame rate control mechanisms (i.e., overshooting and oscillation) are avoided by a semi‐predictive algorithm. The average rendering time per triangle is measured and used to determine the desired number of faces. A set of experiments demonstrates the advantages of both methods.
