A globe that you can rotate through three degrees of freedom by clicking and dragging. Use the handle to move the actual widget.

Technically not a true globe, but with 128 facets, who cares?

Now with night side shading!

This is nice to see, thanks.

I think there are plenty of normal date/time widgets already...

Though maybe I should look into a time set option...

By Tangent128, # Sep 23, 2007 7:44:33 PM

Now make it usable, add date and time

Well actually it is usable, and not just an academic curiosity for the mathematically inclined, it can be used to teach about seasons for example.

It's a Lie!

This is awesome. I feel like moving the globe in the wii.

Yup. I left it open for an hour or so and it looks like it's working

Great job! Now I know when it's night at the Opera office

EDIT: Man, just have to say; this is quite amazing!
EDIT #2: You should put up a new screenshot!

1) It updates once a minute.
2) It should account for seasons; note that the shadow doesn't pass through the poles yet. It will on the equinox, if working correctly.

Two questions about the shading...

1) Does it update periodically while the widget is open? Or is it set only once when it is opened?

2) Does the shading rotate about the poles only, or does it account for seasonal axial tilt? The sun is currently shining pretty close to the equator so it is hard to tell.

Update- v3.0
-Now shades the night side based on the current time and date.

Those extra polys make all the difference - very, very nice! Now you just need to tie into Twitter, or a news service with location data, plot a few flashing lights....!

Yes... I even have an idea as to how to do it...

But it'll have to wait until I catch up on homework.

By Tangent128, # Aug 24, 2007 11:38:54 PM

Okay, so how about this, smart guy:

Add an option to shade the globe where it's currently night, and account for the earth's seasonal axial tilt.

Think that is possible?

By GreyWyvern, # Aug 24, 2007 11:06:23 PM

Well, my skills are more in geometry than image editors, so I'll probably just make an SVG close button in the next version.

I really appreciate the feedback!

By Tangent128, # Aug 24, 2007 6:53:57 PM

~100 more polygons makes it 1000x better! It is a simple globe you don't need a java applet for, or a real globe.

★★★★★ !

EDIT: You could shave another 3kB off the widget by optimizing the close button PNG. It is only 15x45 but it is oversaved at 4kB! You could chop it down to an optimized 64 color PNG at about 1kB.

I wish Opera would distribute optimized version of these graphics in the first place...

MAJOR UPDATE- v2.0
-I've added 108 more triangles, so it actually looks like a proper globe now.

Surprisingly, there wasn't much of a performance hit in doing so. Worth a re-download.

By Tangent128, # Aug 24, 2007 1:58:56 PM

Need . . . more . . . polygons!

By GreyWyvern, # Aug 23, 2007 3:29:04 PM

Update- v1.1; Two notes:
-I've removed the visible seams with a little hack, at the expense of a little distortion.
-I spent the last hour researching the opera-2dgame context, and have speeded up the drawing a little.
