Hi together
A small startup is working on a new user interface called Dizmo. It runs
HTML/JavaScript applications called Dizmos. They are displayed in windows
that can be freely placed and rotated on the display. In fact, their
interface does not assume that the display has "up" and "down" at all.
Also, it is optimized for several users working at the same time on the
same display. It is supposed to work well with touch and various pointing
devices.
I am still collecting ideas for use-cases of this interface.
For example, I think it would come in handy in combination with an actual
PC: Imagine it to be integrated into an office table. You could have ready
the POV-Ray documentation on the side of your keyboard at all times, while
using a normal PC to write your scenes. Also, while working on other stuff,
a Dizmo could show you the rendering progress without taking up precious
space on your main screen.
Also, wouldn't it be fancy to shuffle around your own rendered images like
in in the movie "minority report"? Or maybe allow your visitors to do so
by having a large screen with dizmo in your living room?
Do you have any further ideas related or not related to POV-Ray? I really
like to hear any opinions about the usefulness of their software.
Greetings
Urs

Several users working on the same display implies the display should be
quite large (>30" diagonal). Arbitrarily rotated windows implies you
need a very high pixel density to avoid visible aliasing. Seems like
this would work really well once we have 8Kx4K UHD TVs :-)

It's called "vector graphics". ;-)

In fact, displays that actually work with vector graphics (see
http://en.wikipedia.org/wiki/Vector_display) instead of pixels indeed
existed at some point: Instead of scanning line by line with a cathode
ray you can also scan arbitrary lines.

Dizmo is indeed exploring the limits of available hardware. Maybe it is
the first use case of these TVs with ridiculously high resolution. After
all, who has the bandwith to transmit a TV show in that resolution? It
would also be interesting to see how current consumer graphics cards
cope with such a configuration.

The "some point" would be "the point when buying enough RAM to hold an
entire framebuffer was prohibitively expensive".
While vector graphics has the advantage of smoothness, it has several
unfortunate downsides:
- You can't turn a real-world image such as a photograph into vector
graphics.
- Some effects such as blurring are trivial with raster graphics, but
impossible with vector graphics.

Actually, I don't think anything forces a vector-based display to use
sharp lines. In theory you could have out-of-focus lines, the amount
controlled by the software.

Like attached? Sorry that looks rubbish, I can only imagine how bad it
would look on something with a much lower ppi like a large TV. People
are not going to want to sit up close and use something that looks like
that when they are used to 300-400ppi+ on phones and tablets.

I would guess the card could send primitives to the display and the
display would have a few GPUs to control sections of the screen.
