Method for rendering display blocks on display device

摘要

A method is provided for rendering display blocks on a video display device of a computer processing system having an existing display driver. The method includes the step of assigning each of a plurality of n video adapters to an mth display subregion of the display device. A call to a draw function of the existing display driver is received. The draw function corresponds to a particular shape to be drawn and includes starting and ending coordinates. The mth display subregion that drawing of the shape is to begin on is calculated from the starting coordinates. A function of the existing display driver is called by calling an address stored in the filter driver of a routine corresponding to the called function. The called function corresponds to the received draw function. A segment of the shape is rendered on the calculated mth display subregion by the nth display adapter corresponding thereto. A traversal is made to the nth video adapter corresponding to a next segment of the shape. The next segment of the shape is rendered on the mth display subregion corresponding to the traversed nth video adapter. The traversal and second rendering step are repeated until all segments of the shape have been rendered.
