Earth from space with atmosphere XNA

[zer0sumGames]

Can you share this shader with me? I've been having trouble reproducing the atmosphere effect.

[iCal2]

Which planet is this... and is it hostile?

[kevinscales]

@iCal2 Mostly harmless.

ok I see you are using specular mapping. How did you get the atmosphere like this? Semi-transparent point-sprite?

[Terek81]

nope, i did it with a second pass.

i slightly enlarged the sphere in the vertex shader, and made it transparent in the pixel shader.

[drawmaster77]

ahh ok that works :)

[gibkitt]

ever thought of making a tutorial on this? shader / antialiasing are interesting.

Very impressive effects, I run a blog championing XNA games, do you have plans to make a game from this?

[Terek81]

Yes, i have plans, but its still a long way off.
