What's the best way to draw lots of large textures?

[oNyx]

Well... rotation... you can just cheat there and draw all tiles inside some quad (not rectangle) which would fill up the whole screen no matter how its rotated.

Would be identical to the other version... except that the "screen" is bigger.

Thanks for the pointers. I made it easy on myself and went with oNyxs version But, I do have one more question. In the sample code elias4444 provided: How do you know whats the objectx,y,z after you have rotated and translated? Is there a way to calculate it up front?

The idea is that your track the "center" point of your screen (so, if you sprite stays in the middle, and the rest of the world moves around it, then you set the screencenter to the sprites location on your world map). Then, the onscreen detection is a spherical or cylindrical detection, so rotation should matter.

If you've got an easier way to do it, I'd say go for it, as the method I showed isn't the most optimal way to do things... it was just a bit more straightforward for onscreen detection problems.
