Hello,
I am trying to make a small overmap engine. I would be using a type of heightmap that dictates the height as well as texture to use.
I want to render it in such a way that I can control what part of the map is seen, so that the map doesn’t seem to have any edges, but seems to loop. To do this, I need to know what is visible on the screen (the width and height visible on the screen)and to be able to render what should be seen where it should be seen.
The question then is how can I tell just how much is visible on the screen when I’m not using Ortho? I’m used to exact placement that you get with ortho. But I want/need a depth look that you get with an angled camera.
If there were some way to accomplish this in ortho mode that would be much easier for me. Ether way would work though.
Any suggestions, code, tutorials, books, etc?
Thanks!
Micah
