Abstract

Exemplary embodiments of methods and apparatuses to arbitrarily transform windows are described. Data associated with a first transformation may be obtained. The first transformation may be applied to a first window. The first transformation may relate a first texture point of the first window to a first arbitrary point. The first transformation may include a non-linear transformation. A second transformation is created to a second window based on the first transformation. The second window may be associated with the first window. The second transformation may relate a second texture point of the second window to a second arbitrary point.
