ok ok, it's really a sphere but seen from the ground as on the earth surface this screenshot is in wireframe it was only for a debug purpose (to show the splitting procedure)

I've corrected a lot of bug in my planetary algo. A lot of work to do: calculate the atmos color in function of the hour of the day for example, in function of the camera position, etc ... and allways running on a low machine at descent frame rate. All the screenshot is taken from a hp nx7400 (not a game PC

)

I'm assuming the reason you see a plane and not a sphere is because of the view clipping.. it's too far away so it's not drawn.

you obviously see it's a sphere in the more basic shots.

god lol imagine someone actually faking this.. what a waste of life that would be lol.

so what did u made u only made a big shpere and irrlicht made the rest from only drawing what is to be drawn!>

omar:
no, irrlicht drawn all the mesh and i've written a scenenode which calculate the triangle to add (splitting) or to remove (merging) from the mesh in real time. My Scenenode is used a culling algo only to send to irrlicht the triangles needed.

Today, i'll create a project on sourceforge...

looks really cool, nice work

ah.. memories, sweet memories.. whenever I look up at a night sky it reminds me of the years I wasted playing Elite, Frontier and First Encounters. Still no word on Elite 4, I suppose I don't mind waiting *another* 10 years if it will be as good as the others.

Now the density of the atmos is taken in count. It means that when you land on a planete with a lower density atmosphere you can see the moon or the other planet (screenshot to follow)

Now the atmosphere color depend on the date of the day (darker on evening and clear on day). all this realize with a shader => the upper side of the atmos has a little artefact, i'll try to correct it today. My children are happy for me (i think they prefered to play

)

Means great, cool, awesome, in Japanese. (I think)

High everybody, tonight i've written a shader which generate the planet texture. Now the pattern generated is almost random so when flying at low altitude, it's very pleasant. some screenshot to follow tomorrow...

good night
