Скачать или смотреть Blue Marble 4 - Atmospheric Scattering

Little demo I'm working on to show the Earth from space.

This demo was written in C++ and rendered OpenGL.
I'm using 8K textures obtained from http://visibleearth.nasa.gov/
The code for this demo can be found in https://github.com/mcleary/pbr
The atmospheric scattering shaders were based on Sean O'Neil's code avaiable at: http://http.developer.nvidia.com/GPUG...

In my second demo (   • Blue Marble 2 - Playing with Textures and ...  ) there was no atmospheric scattering at all. The blue halo that can been seen from space adds a little more realism to the scene.

In my third demo (   • Blue Marble 3 - Atmospheric Scattering  ) I was using a blend overlay to blend the color from the atmospheric scaterring with the ground colors, resulting in a strange look.

In this version that bug was fixed and the final look for the Earth was acheived.

Of course I still need some background stars and I have to implement HDR rendering to reduce the excessive brightness generated by the scattering equations.

Ps.: The demo runs at 60 FPS but the video capture tools I was using just record 30 FPS. I have to write a frame exporter so I can control the frame rate later when making the final video.
