Regenerating Nostalgia - Atari Wallpaper

Postby PixelOz » Tue Jan 18, 2011 12:42 am

Hello I,m PixelOz, I'm a graphic artist and I am new to the forum so I say hi to all of you. I'm a big fan of those old Atari St computers although I never had one.

I'm also a big fan of that old Atari 2600 console which I did have and enjoyed very much and I did this wallpaper in Blender for you Atari fans cause I though that you may also like it. You can see a thumbnail here:

http://img28.imageshack.us/img28/922/regeneratingnostalgiaat.jpg

This is the second in the series that started with the old Apple logo wallpaper (you can see that one too in my gallery in Deviantart just click the gallery link at the right) but I decided to give this one a whole different look cause the new Tron Legacy movie was in the theaters at the moment of creating the Apple wallpaper so I decided to give this one a color scheme and illumination somewhat similar to the movie theme.

This is another wallpaper that I did as a tribute to the golden days of computing in the 80s when computers still had limited colors and sound and when they still had limited multimedia capabilities but they were starting to move very fast in that direction. Those were the days when personal computers were starting to move into the mainstream which led to their eventual acceptance in the 90s as another household item so the pretty logo may bring back some fond memories for some people.

It is also a tribute to the old Atari 2600 video games console which I had back there that gave me lots of hours of fun even with its small power and very limited graphics. In those times they were great graphics (imagine that) and it was the machine that popularized the idea of changing the games through the use of cartridges.

It's in many resolutions from 1024 x 768 all the way to 2560 x 1600 pixels in several different aspect ratios like 4:3, 16:10, 16:9, etc. and I also adapted it to 4:6 ratio IPhone format with 320 x 480 resolution and also 640 x 960 resolution. I used very little compression to preserve a higher quality. The IPhone versions were cropped from the high res render so they are not as optimal but they still look a bit good and they also have the old Atari letters logo in them.

I wanted to do something in 3D with a pseudo sci-fi theme cause I like sci-fi a lot. It was started in Blender 2.49b and finished in Blender 2.5x (about the second half of the work) for the Apple version and the color changes to the Atari version was all done in the new Blender and one of the reasons that I moved it to the new Blender fast was because it had a much faster renderer and I was planing to use the internal Blender renderer only and see what it could do cause it has become quite capable and one can get pretty decent results with it with a little bit of effort.

It took quite a while to render (22 hours and 45 minutes) even on a i7 2.66 Ghz CPU using almost all threads (7 threads) cause I rendered it in very high resolution and it uses ambient occlusion and quite a few lights with many samples. It took less than the approximately 36 hours that the Apple logo version took due to optimizations that I did in the lighting. And just like the other it also has some post processing in Photoshop CS4 for some glow effects and a bit of correction of color and light in some areas.

In case you wondering why I chose the .bmp format for this release instead of the more common .jpg format (which I used for the Apple Logo version of the Wallpaper). The reason for this is because of the limitations of the 32 bit image format (24 bit colors + 8 bit alpha transparency). When I did this version as a darker look I noticed that even when choosing 100 compression quality in .jpg files it was still too noisy and I didn’t like it so I decided to use the Windows native .bmp format to distribute it.

This doubled the zip file size but you can then use the wallpaper with much better quality in Windows. Now when you try to set the image through the Set as Desktop Background function of Windows Vista and Windows 7 even if it is a .jpg, .png or .bmp it will save the image to a special folder as a .jpg and with a lot of bad compression.

To prevent this read the included tutorial titled:

HowToPreventWallpaperArtifactsInWinVista&Win7Ver1-1.pdf

So there it is, I hope that some people from the old school of computing, video games and/or sci-fi fans like me and others like it.

You can find other freebies there in my place at Deviantart and Mediafire like a few other wallpapers, icons and paper models and a few other things that I made.

Firstly I like to welcome you to Atari Forums :cheers: hope you enjoy your stay here, it's a great forum to be apart off,

secondly, love your wallpaper, and you've captured the Tron Feel very nicely, I'm sure Tron back in the day, this would of been his place of choice when playing his Atari 2600 :), but the images is a little dark, maybe lighten it with some levels in photoshop just a tad, really looking forward to any more Atari related work you may be doing.

all the best

Agreed, I was thinking the same thing. It does look a tad too dark to me. I will fix it and post and update very soon. :)

Don't worry about the levels in Photoshop, it was rendered in OpenEXR at 32 bit per channels so it's far easier to adjust the illumination with all those values without damaging it.

I also saved that original Photoshop with all the blocking processing masks and layers intact just in case I had to re-process it, let's say I was planning for the possibility just in case so that is why I will be able to adjust the gamma in Photoshop rather easily without having to re-render it or even post-process it completely.

Done. You can download an updated version 1-1 that is a bit less dark. Here is a new thumbnail:

The address to download it in Deviantart is the same:

But the Mediafire address to the file directly is different:

http://www.mediafire.com/?8fiahvuk5p8r59i

I hope that you like this one better. :)

Oh by the way I forgot to give you the address to my Mediafire folder where you can download all my other free things as an alternative to my Deviantart gallery just in case:

Final Corrections

Postby PixelOz » Sun Feb 20, 2011 2:12 am

It has been updated one final time. Version 1-2 has some corrections in the gray areas because in those areas the hues were not correct and it was causing these areas to appear kinda bluish in some displays.

The new one will look slightly more redish in the gray areas in some displays but overall in most monitors it will look much more as it was intended to look.

Also the computer display position has been corrected cause it was wrongly placed in the original Apple version and I finally corrected it.

It also has a few more fixes but they are minor. Anyway bottom line is that I think that now it will look its best. You can download it in the following links.
