To see stereoscopically, just hide the left image from your left eye and the right image from your right eye by your palms and then try to concentrate your sight on a small object located at the intersection of the line from your left eye to the right figure and the line from your right eye to the left image. The "software" is already into the brain waiting for activation. The result is stunning.
After the immovable transparent cube, above, you can try to see stereoscopically the following animated PatDan Constant Velocity Joint (CVJ) mechanism:
At first you can look only at the left (or at the right) image trying to understand what it shows (i.e. how the parts interconnect, cooperate and move).
Then you can try to see both images stereoscopically; follow the motion of any part of the mechanism.
The diamonds, below, "leave" the screen and fly in the space, some moments close to the observer and some moments away, behind the screen (for the DOS "exe" controllable animation click on Diamonds to download the file, then open it; finally press ESC to QUIT).
The Flowers (2.0 MB) is also impressive (click here to download the windows exe controllable animation, then open it, finally double click to QUIT). A "sample" from the Flowers is below:
At first you may be confused but keep trying.
What you see is just a part of the full scene. Move the mouse around. Keep trying.
Seeing stereoscopically is not "a trick" that after a few minutes fades / blows out.
It is a useful tool for inspecting / understanding complicated drawings.
It also fits with video, games, TV.
It also fits with photographs, like the lobster below:
The invention of the "stereoscopic representation" comes from Spain (a few decades ago). It seems it was never understood.
It changes the way human beings see for thousands of years!
The observer has to learn to see combining different "focusing" to "eyes convergence".
In reality, the observer has just to release himself from the conventional way. It seems very few people are ready to make this step.
Most people try a few times and then give it up. They think stereoscopic viewing is not possible, or at least it is not for them.
It seems small children achieve stereoscopic viewing easier.
An old mechanic viewing the "plain" animations of the VVA mechanism on the monitor, said: "It is alive. You do not need a prototype."
If a "plain" (many call it 3D) animation looks alive, how can it be called the "stereoscopic" (or 4D?) animation, wherein the observer feels he/she can touch by his/her fingers the "formed in the space", and not on the screen, objects?
