We present a new approach for dynamic LOD processing for geometry images (GIs) in the graphics processing unit (GPU). A GI mipmap is constructed from a scanned 3D model, then a mipmap selector map is created from the camera position's information and the GI-mipmap. Using the mipmap selector map and the current camera position, some parts of the GI mipmap are discarded using a one-pass shader program that selects the mipmap level that must be displayed and calculates backface culling. Since our method does not require any extra spatial data structure, conceptually it is very simple. Since LOD selection is a one pass algorithm performed on the GPU, it is also fast.
