<If I calcualte the vertical lines I miss the quadrouble speed (enabling the 4 planes). And of cause I can not use the rep stosw/stosd instructions.> This method will be faster for large polygons, but will be slower for small polys. Also it is limited to solid color lines, so it can only be used for no shading or for flat shading. Since you probably want to eventually do gouraud shading and texture mapping, I would not use this approach. I also do not think mode X is worth the trouble, because it will not be faster on VLB or PCI video cards. If you still want to use mode X, I would do verticle lines because this will make texture mapping and gouraud shading faster. I know a quick way to do verticle lines, that I will post once I code it.
