The second generation realistic terrain project. The first version ended up dying as a result of too many changes of mind. This will hopefully be better. The project has a webpage, which has some nice screenshots.
- Import a heightmap and display it.
- Do this by caching data near the player (don't load it all at once)
- Determine the type of terrain at each point algorithmically
- Display this with textures
- Introduce basic vegetation and wildlife
- See from there.
The following milestones have been passed:
- Simple paging
- Simple system of region based rendering
- Dynamic region creation based on camera position
- Use of real data (imported)
- Nice trees
- Shadows
This is alist of high level things that I want to impliment at some stage. Low level stuff to do is found in TODO.md.
- Trees
- [.] Birds
- Colors
- Textures
- [.] Sun and sky
- [.] Sensical terrain types
Use the mouse to point and go. Keys S and W to move forward and backward. Left click to enter/exit pointing mode. Middle click (or o key) to enter/exit first person mode. If you don't have a mouse, use keys A, D, Q and E to move around.
The assets and data are too large to hold in this repo. They can be found here (link may be outdated. email me if it is...) . Unpack the zip file into a folder called assets one directory below where you run the executable. It is worth noting that in the same directory as assets, the folder src/shaders should be copied.
The textures are TGA files. Feel free to chop and change these to improve them. If you develop a better texture, please let me know.
Data is 3m resolution of a 9 square kilometers of a section of North America. More data can be obtained from here.
Whenever I see new code, I hate having to reinvent the wheel to work out how the thing works. I hope that this code is sufficently readable to make understanding it easy (even to those not familiar with OpenGL coding). To this end, I have written TECHNICAL.md which givs an overview of how the code works and what calls what etc. as well as DEVELOPMENT.md which documents my coding style.
There are also some tutorials up on the project webpage (these are currently growing).
