( 2) set a transparent coefficient for each vertex of the plane; as with gouraud shading, the transparent coefficient is linear - interpolated to perform transparent processing in pixel units. in addition to the above, the following setting s can be performed at texture mapping . w hen the most significant bit of each textu re cell is 1, drawing or transparency can be set. w hen the most significant bit of each texture cell is 0, non - drawing can be set. alpha blending type description drawing transparent ratio set in particular register while one primitive (polygon, pattern, etc.), being drawn, registered transparent ratio applied a transparent coefficient set for each vertex. a l inear - interpolated transparent coefficient applied. this is possible only in direct color mode. overlay display blends top layer pixel color with lower layer pixel color transparent coefficient set in particular register registered transparent coefficient applied during one frame scan gouraud shading gouraud shading can be used in the direct color mode to provide 3d object real shading and color g radation. gray scale gouraud shading gray scale g ouraud shading can be used in the in - direct color (8bit/pixel) mode to draw a blend coefficient layer .
