Appreciation

When creating Earthviewer, I used a bunch of free libraries and assets. Here are the most important ones:
Libs
- Open Asset Import Library: 3D model import library
- Simple and Fast Multimedia Library: Multimedia framework, used for OpenGL context creation and window event handling
- AntTweakBar: Provides an easy way of creating a small GUI for tweaking variables. I used it as a debug tool for viewing variable values at runtime.
Assets
- Natural Earth III: Earth image data, going from texture maps to elevation maps. I used a night texture, a cloud map and the land/water mask.
- NASA Visible Earth – The Blue Marble: This is where the day texture is from and I also used one of their Bathymetry maps.
- Ponies & Light Normal Map: The personal blog of @tgfrerer, he wrote an article about extracting normal maps from elevation data. I used his results in my project.
- Milky Way Skybox Textures: Originally made for Kerbal Space Program using Space Engine. Unfortunately I do not know the author because of his reddit and mediafire account being deleted.
I also want to appreciate some tutorials which helped me alot:
Tutorials
- Wikibooks Arcball Camera
- Rastergrid – Efficient Gaussian blur with linear sampling
- Philip Rideout – OpenGL Bloom Tutorial
