Anaglyph 3D - Object out of the screen

15/07/2009 : 3rd test of a computer generated anaglyph movie (OpenGL & C++).

This time, the object is between the screen and you.

As a first step, the helicopter is brought to you, but without the 3D effect. Then it returns to the screen, and the 3rd dimension is added before it does so again.

If you open your hand and put it to the lower edge of the screen, you really feel that the helicopter is over !

There are sequences of static position, so you can try to touch it ! Warning : beware of the blades ... :)

Video resolution : 1280x720 (HD)

As usual, you need colored glasses to see the 3rd dimension. The Red/Blue combination gives the best result.

how do you know, in the 3d software, where is the "limit" of the screen?

how can I know if the object will be seen inside or outside the monitor?

[RubinDrensen]

@henriqvist You decide! In my case, I measured the distance (D) from my head to the monitor, and the angles between the 4 sides of the monitor and the middle between my eyes (H/V aperture angles). In 3D, I positioned the camera (eye pos) C centimeters in positive direction, the camera watching the origin. The origin is then at the screen distance from the viewer, centered in the middle of the virtual monitor. And negative Z coordinates are then, of course, in the screen.

oh, it seems complex...

but what i'm noticing now is that you didn't use parallel cameras, you used crossed cameras, right?

so the screen is in the point where they cross?

[RubinDrensen]

@henriqvist Yes, the screen is at the distance where the points through left and right projection give the same graphical result. Everything before or behind the screen will be horizontaly shifted while you fix the screen. The eye's are at separated positions but share the same target on the monitor (by squinting). That's why the use of a parallel projection to simulate the user's view is a mistake.

i don't know why but i tried to catch it with the hand O_o
