Abstract:
1. A method for accumulative vector drawing using buffering, implemented by an apparatus for the accumulative vector drawing using the buffering, the method comprising: receiving a plurality of graphics commands; sequentially storing the plurality of graphics commands in a buffer; determining a valid definite drawing command that is temporally stored most recently in the buffer among the plurality of graphics commands; rendering, by a video unit having a graphics processor and a memory, the valid definite drawing command on a display, calculating a clipping area of the valid definite drawing command and reflecting the clipping area when rendering unrendered graphics commands, among the plurality of graphics commands, that are temporally stored in the buffer after the valid definite drawing command; and sequentially rendering the unrendered graphics commands temporally stored in the buffer after the valid definite drawing command on the display in an order in which the unrendered graphics commands temporally stored in the buffer after the valid definite drawing command were stored in the buffer, wherein the determining the valid definite drawing command comprises:
