1. A method for providing a fine-to-coarse look ahead in connection with parametrization in a graphics system, wherein parametrization
refers to a one-to-one mapping between all points of a mesh and all points in the corresponding parametric domain, comprising:
parametrizing at least one chart of a mesh utilizing a parametrization metric that generates and optimizes a plurality of
metric values for said mesh, wherein the parametrization metric is based upon a function of at least one characteristic of
the mesh; and
generating a sequence of meshes in a multiresolution representation having a plurality of level of detail mesh approximations
ranging from a coarsest level of detail approximation to a finest level of detail approximation for said at least one chart
based upon at least said plurality of metric values, wherein the finest level of detail concerning said at least one characteristic
of the mesh is taken into account while generating the parametrizations for level of detail approximations coarser than said
finest level of detail approximation wherein generating includes propagating the plurality of metric values fine-to-coarse
from the original mesh to all meshes coarser than the original mesh; wherein said generating further includes generating an
intermediate parametrization by applying a coarse-to-fine parametrization algorithm that is based upon the propagated parametrization
metric values; wherein the presence of said at least one characteristic is one of summed up and integrated, and stored as
information for each mesh face of the fine mesh, to adequately reserve space on the coarse mesh parametrization for the presence
of said at least one characteristic not yet added during said application of the coarse-to-fine refinement process.
