Abstract:

In view of the redundant operations of the three-dimensional clipping by classical algorithm in graphics processor unit and the unnecessary calculation in bilinear interpolation,the article proposes an advanced clipping algorithm,which uses the geometric relationship between the polygon and the vertex inside to calculate the coefficient of the coordinates,and then interpolate the attributes of the point.The simulation results show that the advanced clipping algorithm can reduce the amount of calculation and improve the efficiency of the hardware circuit.

Key words: graphics processor unit;three dimensional clipping;bilinear interpolation
