Apparatus and method for implementing bump mapping in hardware

摘要

The present invention relates to a device for implementing bump mapping in hardware and a method thereof, comprising: a texture model storing a vector value of a bump map, and a color model for obtaining a final color according to a normal vector of a face. And a surface normal liter interpolator (SNVI) that calculates the normal liter value for the plane corresponding to the current x and y axes on the polygon, and registers three bump map values from the texture memory and stores them. ; A subtractor for subtracting the bump map value input from the register; And control logic for controlling the operation of the register and the subtractor, the final color value being included in the color model by the new normal liter output from the subtractor and the new normal liter output from the surface normal vector interpolator. It is characterized by generating.;Therefore, as described above, the implementation of the bump mapping according to the present invention in hardware has an effect of shortening the actual processing time.
