Making WorldPlanet Simulation
By Gustav Olsson
Project Goals
Render a planet with terrain
Terrain
Atmospheric scattering in real time
Water
Level of detail Level of deatil on flat ground
Cube to Sphere
Formula
Level of detail Level of deatil on flat ground
Cube to Sphere
Formula
Chunk with 256 quads
Children
Making the terrain possible
Parameters to generate random number
Amplitude, Frequency, Persistence and Octaves
Frequency = 2i
Amplitude = Persistencei
Perlin Noise
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

Good looking Atmosphere Day and night cycle
Results
Bad implemented level of detail
High Frame drop
Qt do not like release
Problems
Reworked level of detail
Use glew
Solutions
Time estimation is hard and requires practice
Not a one man project
Fun project with okey results
Many improvements can be made
