I’ve got some topographical data which I’ve turned into a height map. Right now the image is 86401 x 43201 pixels, which reflects a very high level of detail. The source data (for anyone who’s interested) was 14GB in size, and the resulting image 2GB in size.
I’m in the process of tiling this into more manageable sizes, but my ultimate goal is to build something into Unreal Engine which will dynamically load the parts that are visible, and will wrap around so you can continue in one continuous circuit around the ‘world’ so to speak.
I’m not new to programming, but I am completely new to game programming. Can anyone suggest some resources to help me get started with this?
The main challenges I see from this are:
- Since the image is square, it means some portions of the world are stretched. I’m not sure if there’s an easy way to work around that, although I might be able to work on turning the data into a cube projection (which might work better).
- All of the ‘level streaming’ stuff I’ve seen to date seems to focus around streaming hand built levels. It’s not practical to craft this many tiles by hand, so I’m looking for resources on producing them through procedural means.
