I’m currently working on a 2d tiled based game, in which when I render many tiles, the fps goes seriously down. I know why this is happening, its happening because they are a lot of objects being created and rendered at the same time. I read that we need something called frustum culling, i’m trying to implement and create that. But I don’t know how to create a frustum from an orthographic projection. I have read many articles, searching all day, but couldn’t find anything that can help.
Note: I’m using VBOs and a sprite sheet.
If you want any of my code, please ask me.
Thanks.
