Title:
Direct manipulation of compressed geometry
Abstract:
A method of spatial manipulation of geometry data describing a graphical object to produce manipulated geometry data, the method comprising the steps of: (a) compressing the geometry data of into a compressed form, the compressing including the step of transforming the data into corresponding frequency domain component data; (b) applying at least one linear transform to the compressed form of the geometry data; (c) decompressing the geometry data, including applying an inverse transform to the frequency domain component data to transform it to produce the manipulated geometry data. The linear transforms can include one of: translation of the geometry data; scaling of the geometry data; affine transformation of the geometry data; morphing of the geometry data; applying a dot product to the geometry data.
