This week have I for the most just researching and started with my sphere with Level of detail(lod). I was in the beginning very unsure how to do implement lod to an sphere because I have only implement it on an flat terrain. So that is what I have been started to research about and found a very interesting solution, which will fit my needs. First I will start with one cube, the cube have 6 sides, up, down, left, right, front and back. With each side represented as each own flat terrain with it’s own lod. This suits me very well not only because it was not to hard to implement. And later on when view frostum culling is implemented, it can easily just cull an entire side.
Here is a picture of the result, it’s looking terrific. Perfectly round sphere. The picture to the right is from mu project, and the other one is for easier understand what I have done. There you can see that the red line represent the edge of the cube.
Level of detail have I started with but it’s not done jet, some small fixes before I can share it with you all!
