1. Making World Planet Simulation By Gustav Olsson

2. Project Goals  Render a planet with terrain  Terrain  Atmospheric scattering in real time  Water

3. Level of detail  Level of deatil on flat ground  Cube to Sphere  Formula

5. Level of detail  Level of deatil on flat ground  Cube to Sphere  Formula  Chunk with 256 quads  Children

7.  Making the terrain possible  Parameters to generate random number  Amplitude, Frequency, Persistence and Octaves  Frequency = 2 i  Amplitude = Persistence i Perlin Noise

8. Atmospheric Scattering Rayliegh Scattering and Mie Scattering Small particals in the air, scatter light more heavily at shorter wavelenghts Larger particals in the air, scatter all wavelenghts of light equally

9.  A planet with terrain Results

10.  Terrain with blending textures Results

11.  Good looking Atmosphere  Day and night cycle Results

12.  Good looking Atmosphere  Day and night cycle  Results

13.  Good looking Atmosphere  Day and night cycle  Results

14.  Good looking Atmosphere  Day and night cycle Results

15.  Good looking Atmosphere  Day and night cycle Results

16.  Bad implemented level of detail  High Frame drop  Qt do not like release Problems

17.  Reworked level of detail  Use glew Solutions

18.  Time estimation is hard and requires practice  Not a one man project  Fun project with okey results  Many improvements can be made Evalution
