Scientific visualization combines the data with graphics to use the graphics and image to show the data intuitively. In order to create intuitionistic three-dimension graphics, the hidden lines must be removed. Regarding the graphics corresponding functions like z=f (x, y), because of the randomicity of the grid node height z (i, j) and the interleaving of the length and breadth sections in the regulation grid, sometimes removal operation is not easy, the removal for the hidden lines from curve surface should be studied to find an effective algorithm used to remove the hidden lines. Based on the peak value scan line technique (Floating horizon algorithm), the interlaced peak value scan line technique used is provided to remove the hidden lines from the function graphics like function z=f (x, y) which gives the implemental process and actual example. It's convenient to use the compositive technique to realize the visualization of the data for function z=f (x, y) within the rectangle field.
