Antes de mais nada também adorei Avatar. A estória não é nova pois desde o tempo dos Apaches nos Estados Unidos ou da Evangelização no Brasil o “branco” não mediu esforços para fazer valer seus intere$$e$. O que mais me fascinou foi que a mensagem da vida comum e integrada da fauna e flora, realçadas pelos gráficos que a atual computação gráfica permite, me fazer chorar por várias vezes. Como os nossos índios sempre o fizeram…

Quanto à moda do 3D achei este artigo muito interessante e esclarecedor. Para versados em alemão o link direto:

Wie gefaehrlich ist 3D?

Para os restantes vai aqui o resultado da tradução macarrônica automática para o inglês, com algumas melhorias de minha parte e a melhor das intenções… ;o)

How dangerous is 3D?

The 3D-Convoy had just startet, and there is already a threat, it could stop abruptly: The Korean entertainment electronics giant Samsung warns before his own 3D-TVs. On the Australian Samsung website there is a list with drastic 3D-TV-Side-Effects: beside visual disturbances there are comments on muscle twitching, cramps, nausea and consciousness disturbances. Generally speaking the manufacturer recommends viewers in “bad physical condition” to avoid 3D. Who slept too little or drank alcohol, should stay within flat pictures.

Even stranger is the reference that 3D-TVs should not be placed near to open stairways or balconies – as this could lead to injuries beacause of 3D-caused disorientation. Such “gaga” behaviour rules shows that Samsung wants to secure itself above all legal issues. Particularly in the USA bizarre warning references (“do not iron the clothes during carrying”) on many products already are emblazoned for years. On the other side there are plausible investigations why 3D indeed is not always harmless.

Human beeings use not only the two different pictures noticed by the eyes (binocular mismatch) for the space perception, but also various other “depth references”. At 3D-films some of those references don’t match. For example the eyes must focus at a 3D-Display on the screen surface, although the actual point of focus of the three-dimensional picture lies behind the screen (in the depth of the 3D-images). This conflict can lead to irritations like the sharpness within the 3D-image: it does not match with the sharpness perception within a real 3D-scene – in particular if the viewer “walks” with his eyes over the 3D-image. This way the sharpness does not change as in the real picture due to the respectively eye movement acomodation, the normal relation between detail sharpness and object distance does not apply here anymore. The viewer must dissolve this conflict by decoupling acomodation and eye movement (vergence) – this can cause uneasiness and tiredness.

If the brain begins to solidify the uncoupling of sharpness and acomodation as well the different focus levels, the viewer in the real life losts the necessary reference to spatial seeing. Normally this “binocular Dysphorie” puts after some minutes – advocates of a theorie do not exclude however that the risk of a permanent spatial false perception with children exists and are high. The consequence to the frequent 3D-viewing for example is loss of spatial vision.

Such problems with 3D-screens are quite discussed by the manufacturers, also on international level many large institutes in Asia, Europe and the USA research them too. A working group of the international standard organization ISO is occupied with “image safety” likewise with the potential danger when watching at 3D-screens. Concrete results over possible long-term injuries when viewing 3D were however not yet designated.

Para mim o ingresso se paga quando a historia, os atores, o diretor, o conjunto é espetacular. Avatar é longe disso. a historia é banal (na minha opiniao) mas os graficos sao muito bem feitos, sim.
Mas se compararmos à Alice in Wonderland de Tim Burton, pelos estudios Disney, também em 3D, fica a pergunta de porquê mesmo estes oculos na nossa frente?
A historia eh fantastica os atores sao otimos o diretor eh incrivel. o 3D? ah..ta em letras garrafais no cartaz, como se precisasse disso para vender mais. Ou seja, desnescessario!

em resumo, 3D é ótimo como entertainment mas nao faz cinema.
e ainda tem muito caminho pela frente…

Aquele abraco.
