The invention relates to a method and a system for romancing three dimensional objects in three dimensional game units to romance figure's head. The system comprises mapping storage module; parameter getting module; angle calculating module; judging module and romancing module. The method comprises: establishing a multi angel mapping group according to game figures' heads and storing mappings after number. The method comprises steps of: extracting some individual vectors of figure moving directions and vision directions; calculating an angle parameter according to the extracted vectors by the angle calculating module; the judging module judging the needed heads mapping number according to the angle and then confirming corresponding head mappings, romancing figures' heads to lower the necessary image account during establishing figure module and realizing display figures' head more clearer. |
