Abstract:
A computer-implemented method for computer-generated graphics of an object using a mesh, the mesh representing a multi-dimensional model of the object, the mesh having geometric elements and associated resources encoding attributes of the geometric elements, the method comprising:producing sequential graphic images depicting a changing view from a viewpoint of the mesh; evaluating the geometric elements relative to the changing view of the mesh from the viewpoint to determine mesh alterations to be applied to the mesh to effect view-dependent adaptive level of detail adjustment of the mesh, wherein the evaluation of the geometric elements for view-dependent adaptive level of detail adjustment is apportioned over the producing of multiple of the sequential graphic images such that evaluation of the geometric elements is apportioned into multiple nonempty sets of geometric elements and portions having fewer than all geometric elements then present in the mesh are evaluated per graphic image produced; and varying the geometric elements from a first state towards a second state of the mesh after application of a first set of the mesh alterations, wherein the varying the geometric elements also is distributed in time over multiple of the sequential graphic images.
