发明名称 Data retrieval method and system
摘要 One aspect of the invention is a method for data retrieval. The method includes the step of rendering geometry from a selected perspective ( 140 ) to produce a plurality of data values ( 130 , T'<SUB>AB</SUB>). The method also includes the steps of storing at least a subset of the plurality of data values ( 130 , T'<SUB>AB</SUB>) in a memory ( 40, 80 ) and computing a plurality of texture coordinates (a'-d') of the geometry from a projective transformation corresponding to the selected perspective ( 140 ). The method also includes the step of retrieving at least one of the stored data values (T<SUB>AB</SUB>) that correspond to the texture coordinates (a'-d') from the memory ( 40, 80 ).
