Newly relocated to London, the very heart of the British Galactic Empire, Neal complains and complains.

Eye consider the imminent move to London (warning: video contains cats)

Part XII. Safe aboard the Dirigible Of The Imagination II, Neal sums it up

You see, the thing is: I hate writing. Always have. I find it tedious and exhausting and very difficult. But it seems to be something I'm good at.

So, yes, there is a Devil, and he gets you in the most cunning ways.

I would much rather show off than write. If...If only I could find a way to mix showing off - shameless exhibitionism - with writing, well then, my life would be almost worth living, wouldn't it?

I know! I'll broadcast a LIVE video feed of me at work! And make it available to anyone and everyone in the world! And then...then I'll be happy.

So check on Monday, 1st June, 12 noon GMT, go to my LiveStream feed at:

At noon (GMT), for an hour each day, you'll get to see inside the monkey house. And live chat will be operating, so you can throw me peanuts. And maybe I'll throw back some poo.

As Peachy Carnehan said in "The Man Who Would Be King" (1975): "Keep looking at me. It helps to keep my soul from flying off."

Solving 3D Headaches:
Matt Brennesholtz Helps
Negotiate A Challenging 3D Future
By
Neal Romanek

(as printed in April 2009 TVBEurope)
“I love watching 3D, it’s just that after 10 minutes I have a pounding headache.”

At tradeshows, exhibitions, screenings, even meet-ups of 3D devotees, one hears it over and over. At the Digital Television Group's Summit 2009 in March, an overview of Sky's plans for 3DTV was introduced with "Here's Chris Johns to tell us about eye strain."

There has been a mad rush to produce 3D content even though their may not be the viewership for it. Critics vocally wonder if the producers of 3D content are living in a fool's paradise, preparing for The Next Big Thing that may never come. The Beijing Olympics was touted as the "3D Olympics". 3D trials were to play in limited markets, primarily in Asia. The fact that few people have heard that Beijing was the “3D Olympics” may suggest how successful the experiment was.

Creating dynamic, believable and commercially viable 3D images is a challenge that has been around longer than most people suppose. 3D is usually associated with the 1950's and the spate of anaglyph-based 3D feature films - although the anaglyph technique had been used to create 3D images since the 1850's. The first stereoscopic motion picture patent was taken out in the 1890's and the first 3D camera rig was patented in 1900.

TVBEurope talked with 3D expert Matt Brennesholtz, a senior analyst at Insight Media who has worked in partnership with the 3D@Home Consortium. The 3D@Home Consortium was formed in 2008 to speed the commercialization of 3D into homes worldwide. It also attempts to facilitate the development of standards, roadmaps and education for the 3D industry. In 2007 Brennesholtz co-authored a 400-page report “3D Technology and Markets: A Study of All Aspects of Electronic 3D Systems, Applications and Markets”. This all encompassing document forecast the viability of 3D display technology in a vast array of markets into the next decade. Its scope included not just stereoscopic 3D displays, but a variety of autostereoscopic displays, and rotating image plane, vibrating membrane, and micropolarizer technologies.

Brennesholtz is an expert in display technologies, having been a lead projection system architect at Philips LCoS Microdisplay Systems. He has a masters of Engineering in Optics and Plasma Physics from Cornell University and has been granted 23 patents. Still, we asked question most on everyone's mind - why do we get a headache when we watch 3D?

"One of the fundamental problems with 3D displays," he explains, "is the problem of convergence and accommodation." Convergence is the ability of the eyes to stay trained on a point in space and allows you to focus on the text on a mobile phone three inches from your nose. Accommodation is the ability of the eye itself to focus in distance like a mini-camera.

Stereoscopic images rely on the brain's default setting of always making a single image out of the pair of images received by the eyes - as opposed to how chameleons do it. The perceived "space" between the two side-by-side images in a 3D show is compensated for by convergence with the eyes going from being parallel towards being crossed and back - just as they would in watching a live event.

The element that is challenging for the brain - and for some viewers - is the image in a 3D display is always exactly the same distance away, on the surface of the screen. The convergence of the eyes sends the message that objects are moving forward and backward in space, but the real image each eye is capturing stays put. The brain is trying to tackle two different ways of seeing at once, like a computer running two memory intensive applications at the same time. The fact that the eyes are making very few focus changes, doesn't mean that the brain is not revving like an engine every time it thinks something is moving toward it or away from it. Perhaps, like the trick of being able to pat your head and rub your stomach at the same time, the brain may get the hang of it with repeated viewing.

"There can be other human factor problems associated with bad 3D displays," Brennesholtz notes, "with certain types of encoding, for example, but this is a fundamental problem that really is inescapable in the 3D display world."

The most serious aggravation of the accommodation-convergence discrepancy is when the content creator puts images in the virtual space in front of the screen - the monster reaches out to camera, the enemy fires a hundred arrows at us, and the like. These are the effects that producers may push because they have greater visceral impact, but they are also the things that most bother the eyes. Brennesholtz says the solution is to place most 3D effects at the level of the screen or behind it.

Another significant issue, one to induce headaches in content creators rather than viewers, is that the content has to be created for the screen size and viewing distance of the intended audience. Analogous to needing different sound mixes for DVD, theatrical, and mobile device content, each 3D version of a programme must be mastered with its final destination in mind. Sound mixers have managed complex sets of presets for each intended format, it seems likely that 3D mastering will have to learn to do the same.

Although some roadblocks to the perfect 3D experience are exactly the same as they were in the 1950's, Brennesholtz points out that the sophistication of today's technology may overcome the others. "Some of the other problems that have been associated with 3D, like dimness or differences in brightness and color between the two images, can be overcome with proper display, screen and video signal design."

Brennesholtz underlines the consumers demand for a quality experience that is the principle factor in adoption of 3D. “The end user, whether he’s watching broadcast television or cable or blue ray or is sitting in the cinema, is not going to give up anything to get 3D. He’s not going to give up resolution. He’s not going to give up frame rate. He’s not going to accept flicker. He’s not going to accept headaches. Basically, he wants his 2D experience – which right now when you look at HDTV is really good – but with 3D.”

Questions about 3D are in no short supply. Approximately 10% of the population are unable to properly see 3D, and what kind of a strategy must be developed when such a large segment of the audience must automatically be discounted? Most people are unaware that many TV's are already "3D ready", but where is the extra bandwidth going to come from if 3D TV is going to become a reality? And finally, if eyeball convergence and focus are such core issues in 3D viewing, what happens to the 3D experience after the third beer?

TARZAN, MON AMI
(from his faithful friend Paul d’Arnot, Capt.)
by Neal Romanek
How princely you are, my friend,
In the new suit from La Confection des Élysées.
How you honor them
By condescending to wear it.

When I was in the jungle
With you, at your mercy,
I was afraid of you.
Now here in La Ville-Lumière,
Where no man like you has walked for 10,000 years, now you are afraid.

You showed yourself to me, naked in your jungle - the only fearless man in all the world.
And now I see you, hackles up,
Moving from stillness to stillness like an unquiet animal.
When the marquise shakes your hand and says “Honored. Honored,”
You smell the blood on his
Breath, and you chill and wonder why no one else does. Are they all in league?
When the girl in service curtsies, says “Bonjour, monsieur,”
You hear her heart breaking, and you wonder why no one else does.

Return to the jungle my friend, out of this dangerous place.

Return to the tranquil jungle, under your mother’s canopy,
Where the names of things come easily to your mouth, where things are called what they are.

Every word of French I taught you - like ashes in my mouth.
I said "God made you a gentleman at heart, my friend”!
Dieu!
I feared you so.
I hoped to make you into something more like me. How could I know that I was making you More dangerous with every word? Injecting you slowly with urbane distemper,
Pasteurizing you with good intentions.
When tantor became l'éléphant,
Numa, le lion,
Hista, le serpent - per Académie! -
I turned the sweet opera of your world
into the jeers of packs of lunatics, the whoops and hoots of cannibals.

That you would save my life and mother me back to health and I in repayment, would set the dogs on you.

Forgive me, Tarzan.

There was a moment, mon ami, when you were almost saved.
Do you remember? Did you know?
I put on my helmet, ready to go,
Picked up my revolver from that wide table stump, the one I’d made my toilet table.
And - perhaps in fever still? – abruptly threw it into the brush.

I didn’t know why then.

But I know now. After that month with you, I felt so naked, vulnerable, clinging like a child to his rattle. I had to throw it away or lose all my courage forever.

But you retrieved it for me.
You dived after it.
You put it back in my hand.
“Tu, tu, tu, tu, tu!” you chirped like a jungle bird, pressing the revolver on me.

And I accepted it.
I shouldn’t have accepted it, should I?
I ought to have thrown it again, farther still, and turned my back on you.
Should have run away down to the river and never seen you again,
Emerged from the jungle a better, braver man.

I waited for you to run away,
While hoping you’d stay
To lead me home.
Hoping – again, yes – that you'd do my work for me. Poor slave.

By nightfall, you had brought me to the Solomougou Post
Where the men smelled like bloody earth
And more vermin creeped than in the deepest jungle.
I held your arm.
Together we found a man who would take us down river next day.

All night you perched in a tree - do you remember? -
Watching the coolies, after hours, stagger and sing below.

On the river the pilot asked many many questions about the strange white man out of the jungle -
Not about me, one more European out of his depth - about you.
I answered them. I answered all his questions!
What a villain!
The gall I had to answer his questions about you!
Maybe I was fevered still. Not in my right mind. Not in my right mind.

Forgive me, Tarzan, my White Skin. Forgive me.

C'est une drôle d'idée - that you should be “White Skin”.

Among my shallow, colorless people, you are deep and black as your rivers, deep and black as your night,
Deep, black as the great expanse that cradled and suckled the world before the mind of Le Dieu blasted away all that was peaceful, wiped away all that made sense and was sweet and perfect.

I have a black top hat and a black coat. And in Belgium the winters are white and and wide and cold.

The Africans, in those hell-squalors we saw along the river,
I swear I saw them shed tears at the sight of you.

I swear I heard them sing:
“Oh there goes an African. Africa has made that man. And only Africa made him. He was not deprived of his lordly heritage, no. No. He was rescued and exalted. Exalted by the land. Saved by Africa. Taught by Africa to be strong and wise and to hear all the knowledge pouring in like cataracts from within, from without. Oh, Africa, that unites spirit and mind. Oh, Africa, that unites heaven and hell. And, look, they are taking him away! And they are taking him away!”

Mon Dieu, my white ape.
I have returned you to the hands of your captors.
I have delivered you back into the clutches of the slavers.

Forgive me, Tarzan.
Forgive me, Tarzan.
