Weekly Progress
2012-04-29
- Create repository by importing from kuxv's, and create this wiki page.
- A small fix to make it compilable on my x64 system. Then it runs quite well.
- Merge new changesets from trunk.
- Confirm my development environment: Thinkpad T410s( Intel i5, Nvidia NVS 3100M, 8G memory ), Ubuntu 12.04 64bit. I also have a Win7 64bit, but only for testing.
2012-05-06
- Some code cleanup.
2012-05-14
- Keep on warming up with the code.
- Start drawing a sequence diagram to show the work flow of LOD and paging.
2012-05-20
- Finish the sequence diagram, and get to understand most of the previous implementation ideas.
- Have found some possible buggy point. See them above for detail.
2012-05-27
- Start reviewing the code, I think I have understood the idea deeply.
- Small refactoring, extract out a TerrainLodManager, which makes the Terrain component as clear as the original.(80% completed)
2012-06-03
- Almost finish extracting the LodManager from Terrain.
- Going to read height/delta once for all.
