“No glasses” 3D Holograms?

Light Field Labs has raised an additional US $28 million in funding to develop and produce free air holographic display technology. They are said to have a working prototype now and the additional funding will enable them to scale up to an actual product.

The aim is to create holographic objects that appear to be three dimensional and float in space without head-mounted gear such as augmented reality or virtual reality goggles.”

The principle people behind the technology had developed the Lytro camera technology. As best I can tell, it may be similar to a digital implementation of a conventional, analog, film-based hologram. In the original hologram technology, you look at a flat image that is, basically, like a window pane. As you move to the left or right, you see the true 3D image visible from that point in space. In the laser-based hologram, the window pane is a film that has recorded light interference patterns.

From the description down the page, here, my interpretation is they have created a currently small window pane that is replicating the light interference hologram concept, but in the digital domain. Obviously, it takes a tremendous amount of computational horsepower and for video, high bandwidth, both of which are becoming available as tech advances.

I presume, also, that this technology can be used to project objects in front of the viewing plane, as is done in stereoscopic 3D. In other words, actors or objects can be appear to be between you and the viewing screen – or behind the screen.

This tech creates true 3D that does not require glasses for viewing.

3D box office revenues have taken a steep dive, with box office sales at their lowest level in eight years. It may finally be time to say sayonara to those bulky tinted glasses.

I would be overjoyed on the day that 3D finally bites the dust. The tinted glasses overly darken the screen, and the rare effects that cater to the technology often only serve to make me woozy.

The reporter writes about films but when it comes to 3D, is a dufus – movie theater 3D glasses are light weight, clear, polarizing filters, not “bulky tinted glasses”. The reporter believes she is wearing tinted glasses when she is not – apparently does not understand the concept of polarized lenses. Since she does not like 3D (sample size n = 1), then no one should enjoy 3D. Wow. If she doesn’t like 3D, then she does not have to watch it, but alas, she wants 3D to be gone because no one should enjoy 3D 🙂

‘Avatar 2’ sequel in 2020 could kick start #3D again

Avatar was a huge success and caused many studios to rush out 3D conversions of existing 2D content – but which were, frankly, terrible conversions.

Certain studios took the time to make high-quality 3D films, but some films that were put into 3D were garbage. As a result, not all 3D was created equal,” says Eric Handler, a media analyst with MKM Partners. “There was a lot that people didn’t want to pay a premium for anymore.”

There’s hope from certain sectors that the release of “Avatar 2” in 2021 could reignite passion for the format. Cameron is planning three subsequent sequels in the coming years, with a fifth installment wrapping things up in 2027.

Watch Star Wars: The Rise of Skywalker in 3D?

The reviewer notes that significant scenes are very dimly lit, very dark, and these types of scenes do very poorly in 3D:

Star Wars: The Rise of Skywalker isn’t the worst 3D conversion in Star Wars history, but it certainly doesn’t hit the lofty heights of Star Wars: The Force Awakens’ 3D conversion efforts. A decent end to a saga’s third dimensional run, there are stumbling blocks that could have been avoided, but weren’t.

If you’re a 3D fanatic, this presentation isn’t a total waste of time, but it won’t rival some of the best examples of the medium we’ve seen in recent years. However, if you’ve been catching up on all the other films in 2D, you might not want to dive into the world of Star Wars’ 3D universe with this particular film.

I am a 3D fan but will probably not see this in 3D. Partially, I need to drive about 20+ miles (30+ km) to the nearest theater where it is showing in 3D versus driving just over 1 mile (1.6 km) to see it in 2D 🙂

3d.coldstreams.com has moved to a new server (this one)

On December 18, 2019, my Internet web hosting provider announced they are shutting down in February 2020. I am now in process of relocating my 5 web sites to a new web host (and once this is done, a 6th site located elsewhere will also be relocated).

This post you are reading right now is on the new web host, however, the final appearance of this page and some other key items still need to be updated. These final fixes will occur over the next week or so.

Unfortunately, the instructions I had for migrating a WordPress web site to another server were incorrect and only “sort of worked”. These incorrect instructions appear widely on the Internet, unfortunately. After migrating 3 of my 5 web sites, I discovered the instructions did not lead to a fully functioning web site. Consequently, this process has become more complex and time consuming than expected.

I ended up inventing my own migration strategy however it may require that I temporarily run a brief function on the old web server. To do that, I may need to temporarily re-assign the DNS to point back at the old web host server, and then reset it back to this one. That will occur sometime during the coming week (but I have an idea that might avoid this step altogether – we will see!). As a result, the appearance of this web page will be going back and forth during the coming week or so and will not be finalized for another week.

The following web sites are affected and will be in a state of transition during the migration over the coming week.
