Freeviewing the Internet - 3D Adventures Await

No Stereoscope RequiredStereoscopic vision is one of those miracles of the human condition that is all too often taken for granted. If you are fortunate enough to have two functioning eyes then you posses the ability to view the world in three dimensions and thereby have the tools required for depth perception.

When you look at a single object with two eyes you are actually presenting your brain with two separate images that it must meld into one. The average difference in eyeball separation is only 2-1/2" to 3" but that is all it takes to discern depth in three dimensional space.

The Holmes StereoscopeNot very long after the invention of photography it was realized that if two photographs were taken of a single object with the same separation as the human eyes, these two images could be used to relay a three dimensional view to an individual via the use of a device known as a stereo-graph or stereoscope. The stereoscope would accept precisely mounted images (or view cards) on one end and the user of the device would peer through a couple of magnifying lenses (one for each eye) and would be treated to a picture set that would trick the mind into melding and interpreting as if the viewer were standing at the original camera location. The result was so awe inspiring and entertaining that "Stereopticons" (as these viewers were sometimes called) became a sensation. As a result of their popularity a grand industry arose whereby anything worth photographing was photographed in stereo and marketed to the connoisseurs of this fascinating pastime.

To this day there continues a very active community of Stereoview enthusiast. An internet image search using the word "stereoview" will send you into an incredible World of 3D photography to an extent that borders on the unbelievable.

Bunny, Goat and Baby

To those of us that have mastered the art of freeviewing stereo pairs the internet now offers the ability to see back in time and far away places. You too can enjoy this hidden treasure trove by learning the technique known as freeviewing, which is the ability to render stereo pairs in glorious 3D in your minds eye without the use of a stereo-graph device of any sort.

It is the purpose of this article to help impart the skill of freeviewing to the uninitiated in the hopes that you too will use this simple technique and enjoy this remarkable pastime - this window on the world of long ago - this time machine available at your fingertips.

So what's the secret?  [Continue]

Throw BlogDogIt A BoneI have been having fun with the BlogDogIt "Friends - Link Exchange" (over to the right there - in case you missed it.)[smiley:;)] I have made several friends and have hopefully generated some traffic for them. I also have them to thank for bringing visitors to BlogDogIt by virtue of their display of the "BlogDogIt Tag" on their site, as part of the "Throw BlogDogIt A Bone" initiative.

I was facing a delima in that I had several links posted in the link exchange simply because they contained links back to BlogDogIt while not actually displaying the "BlogDogItTag." I still want to promote those sites but I really feel that the "Friends - Link Exchange" needs to stay true to its intended purpose.

Today I completed what I think to be a fine solution: I call it "Friendly Ad Roller" and right now it is displayed in the upper left corner of every page. This feature displays a randomly selected link-back graphic to one of our friend's websites. The pool of ads contains the official link exchange participants as well as other folks that I would like to bring to your attention.


Scroll this Box for the full "Rotation" of available Ads.

Not Yer Pappy's Capcha

You Mean Cracha?

In the last couple of weeks the nogoodniks have taught their robot armies to defeat the Geeklog® Capcha system and as a result BlogDogIt has seen an explosion in new members. I hope that the robot's feelings were not hurt when I deleted their shiny metal asses.

::Ben over at Geeklog.fr wasted little time devising a foil for our Cracking Nemessi. He chose to utilize the slider control in place of the vision test to determine your humanity. Geeklog operators (V1.8.0 and up) will want to pick up Capcha plugin 3.5.2 from Geeklog.fr.

Smooth Operating Capcha

It will be interesting to see how long this little brain storm will hold the spammers at bay.

This device replaces all instances of the old-school Capcha around the site here. Please let us know if it causes you any problems (unless you are a robot in which case you can choke on it.) [smiley:;)]
