Hey, nice :) That's an interesting way of giving the illusion of a stereo depth field through movement.

Nice application! ... ( 10 months ago by krytharn)

Nice application! It's not as visually pleasing as Johnny's demo, though. I think you need to tweak the camera response a bit. But it's cool nonetheless.
Let's hope mr Ravengamer will not polute this comments thread with his crap.

thanks for posting. very interesting. i cant stop watching these videos so i will have to go ahead and try this for my self. Great video

If you mean the video camera, I later discovered that focus was set to manual rather than auto. :)
If you mean the worldwind "camera" I agree...it's not working entirely naturally but is kinda midway to work both at high altitude and very close to the ground.
The behavior should be more closely tied to altitude but I haven't had a chance to play with the math.

Fantastic! What a great application of a great idea! Combining your tech with Johnny's was awesome. So many areas from education to feildwork could benefit from this.

Hi Nigel,
I indeed meant the virtual camera. The change in viewing position in your application is not as dramatic as in Johnny's demo, so it is a bit harder to see the difference in camera position. Try to see the center of the television screen as the origin, and the position of your head as the camera position and position the world (landscape) accordingly. Maybe that improves the effect. Cool work nonetheless, Nigel.

thanks, nice to see an application with a more complete 3D scène
in fact since the concept is to have the computer screen acts like a window, I think the depth effect is more evident if you are closer to the objects of the scène, because the paralaxe effects gets way more noticeable, and this is what create the depth.
I don't know if engines like Half Life 2 allows such intereactions with the engine.

Wow great ... ( 10 months ago by lucidlenny)

Wow great application of the technique.
Kytharn, Remember that Johnny's example had targets that were "beyond the plane of the viewing screen" I think the terrain would be more dynamically 3D if it were to virtually bisect the image plane; or come out of the screen a bit.(this one is closer to the stadium example)

not sure if you ... ( 9 months ago by dinther)

not sure if you achieved the effect Johnny did. The idea behind this head-tracking is to shift both the camera position in the scene AND the rendering axis which needs to be off-axis as you move from side to side. This requires access to low level features of the graphics engine. You'd need to call either glFustrum in OpenGL or PerspectiveOffCenterLH I am curious to know if you have that level of access to the World Wind application.

Wouldn't this be cool if someone put tech like this with a rotating TV?

I second that. This ... ( 7 months ago by Series8217)

I second that. This is simply wiimote movement control. Johnny projected a perspective transformation onto a rotated plane representing the screen, to correct for viewing the flat panel off center. It looks like this is just moving the camera around a bit with the head motion.

hahahahahaha this guy wrote World Wind(c#, MDX) one of the first programs to use satellite data to make terrain of 90% of the world; MS flight simulator around the same time did the same thing, not quite as expansive tho. Yeah he has access to world wind code.

these videos are a true inspiration. I must go and create something to take advantage of this novel use of existing technology. Jonny's TED demo was my entry to the subject and went down a storm and rightly so. I can seee so many applications for this if combined with video projection equipment, eg medical scanning in realtime with the scan projected directly onto the patient. The surgeon could walk round the patient viewing in realtime the internal organs layer by layer.

i had the idea for a spherical multi touch monitor that doubled as a globe, oversized trackball and light sculpture. this aplication is just made for it. wish i had continued work on the design now.

where can i buy it? ( 1 day ago by fuldaonline)
