According to the User Guide, an ordering table is used "for controlling the proper display of polygons". Polygons means 3D, however I've seen OT's used in 2D graphics programming as well as a simple "Hello World" program. What gives? Here is MY analysis: An ordering table is actually a place where you insert a list of instructions on where to place sprites on the screen. It basically holds all of the locations of each object on the screen. When the list is complete, you call GsDrawOT() to place everything on the screen that is defined in the table. Is this correct? If not, please clarify for me as it seems to be an essential step for placing any kind of graphics on the screen. Also, how do packets fit into all this? Thank you very much in advance! Nelson.
