//DL facts:
|
|
// Ikaruga uses (nearly) NO display lists!
|
|
// Zelda WW uses TONS of display lists
|
|
// Zelda TP uses almost 100% display lists except menus (we like this!)
|
|
// Super Mario Galaxy has nearly all geometry and more than half of the state in DLs (great!)
|
|
|
|
// Note that it IS NOT GENERALLY POSSIBLE to precompile display lists! You can compile them as they are
|
|
// while interpreting them, and hope that the vertex format doesn't change, though, if you do it right
|
|
// when they are called. The reason is that the vertex format affects the sizes of the vertices.
