For those of you interested in these things, check out this OpenGL project i coded last week:

(everything virus checked, no worries)

Download: http://www.cjultra.com/opengl/planet.zip

You also need to put this file in your system32 folder: http://www.cjultra.com/opengl/glut32.dll

Instructions:

Extract the contents of the zip file in a folder.

Run main.exe

You will see a blank window. Now you can use the right click menu to draw. Click on the following selections:

- Draw planet sphere
- Planet texture -> earth.bmp
- Draw cloud sphere
- Cloud texture -> clouds.bmp
- Cloud transparency
- Cloud shadows

You can use the left mouse button to drag and rotate the planet. Also you can use the Animate option in the right click menu to make it rotate smoothly (clouds and planet rotate at different speeds). You can use the wireframe mode to see the wireframe model of the planet. You can use culling for increasing the performance; it doesnt draw the opposite surface that is not visible to the camera if it is enabled.

You can use your own textures with the program. But they have to be 2:1 in size and the dimensions have to be power of 2 and extensions need to be bmp. So they have to be like 1024x512 or 512x256 or 256x128 etc.. When you run main.exe, it will detect them all and add to the list inside the program.

here are a few screenshots (but it looks much better when you run it from your PC):

here is the sourcecode:
