Good questions. My family operates farms for wheat and corn, and I've been involved in that process, so I can take a stab at answering the last bit:

Corn stalks get quite tall -- 6 feet / 2 meters or so. Each stalk usually has 1 or 2 ears of corn. On our farm, the experience I had suggests that each plant needs quite a lot of healthy leaves for Photosynthesis as well as quite a lot of available ground water. Irrigated corn often produces 2-3 times as many bushels per acre as compared to "dryland" / non-irrigated corn.

So the issues I can see potentially clashing between corn production and vertical farming are:

1) You'd have a greater space requirement for layers of corn since you'd need probably 8-10 feet per layer, as compared to what looks like 2-3 feet per layer for leafy vegetables in the video. Approximately one story per layer wouldn't allow for the massive footprint savings like in leafy plants without getting extremely tall, which would be expensive for water pumping etc.

2) Corn root systems are pretty deep to support a tall and relatively bulky stalk. Getting that to bite into a thin layer of fabric / recycled plastic to provide structural support for the plant would be difficult. I think you'd need to have a thicker bottom layer *and* to manually place further support lines on the stalks as the plants grow, which would get very labor intensive and therefore expensive.

3) The vertical nature of a corn stalk suggests that the overhead motion of the sun might be pretty important for getting light exposure onto all of the leaves. Fixed overhead lights might mean that the top leaves get plenty of light but the ones lower on the stalk would be shaded by those above and get nothing -- which isn't a problem if the sun progresses through low angles at sunrise/set to overhead at noon throughout a day. So you might have to have lighting that hits from all sides to account for that with corn, which would again add expense.

4) To maximize the output, corn needs a LOT of water. Pumping that up the vertical expanse to get lots of levels could easily get problematic. Corn will grow without optimal / abundant watering, and their misting system would likely be more efficient than irrigating to add ground water, but the main benefit of vertical farming seems to be high output in a small land footprint on the ground. So without LOTS of water, you'd be limiting that benefit.


So basically, my guess is that vertical farms are a fantastic idea for squat, spread out plants like lettuce, but a lot of the advantages disappear when you're talking about something tall like corn. I could easily be wrong about any/all of that though.

The short answer is "It depends!"

I know it's a crappy answer, but there are way too many parameters at play. There are many games today that have scripted scenes in them that are pretty cinematic. Think of GTA III, from 2001. The cut scenes in that game still outshine the actual gameplay of GTA V today.

If the scene is scripted, then all the animation, and camera movement can be fine tuned and all compute resources are pooled into the viewport of the camera. This allows the artists to focus all of the trickery on the shot itself, but not the rest of the world. From a PVS or scene-graph stand point, you have pretty much reduced the complexity to just what you are seeing.

I do not know how they made this demo and cannot comment on it with any authoritative capital. I've written 3D engines before (not for videogames though) and can comment on the technology I think I'm seeing here. My comments are just an opinion based on what I know. I do not have access to Unity and have never used it before. But here it goes:

For a scene like this, there should be reduced/canned computation in:

• Collision detection and response
  
• AI
  
• Animation / IK
  
• PVS
  
• Texture Atlasing
  

The shaders, unless they are geometry (the ripping of the skin/flesh in the Adam scene) could or could not be reduced in scope and complexity. I am not sure if they are scripted or dynamic. By scripted, I mean a geometry shader that reads vertex data from a VBO stream or some memory buffer instead of computing the vertices on the fly. It's still real-time, just not dynamic.

Most of the graphics you see here are standard applications of technology that's been around for a while:

• PBR shader
  
• Motion Blur Shader
  
• Depth of Field Shader
  
• Cascaded Shadow Maps Shader
  

The particle system seems pretty standard as well.

This is a great demo and I am extremely impressed with the art direction, but the engine itself is, after all, Unity with PBR for the characters, and maybe Global Illumation for the indoor scenes, which I believe they licensed from Geomerics.

Not only did the record the video vertically, they then added pointless blur to the side, so it wouldn't look vertical and you can't even watch it full screen vertical!

Dumbarse.

Let this be a lesson of the dangers of the vertical video... Completely missed all the action, which would have been caught if this person had a clue.

That actually didn't clarify it for me at all.

My other question is, how does the damn banner stay vertical in flight?

Vertical video accepted.

Yah, I started out thinking OK this goes in the EIA channel but after reading the daily herald article I realized that I love this guy. After realizing he wasn't going to make it to the basement or wherever his wife was (just as well) he proceeds to video the event. And he didn't vertical video it. This really brings home for me the actual experience of living through a tornado and how every survivor you ever hear compares the sound to a locomotive.

I'd run away too if I was being filmed vertically.

Hey, we’ve found something more annoying than vertical video, not bothering to straighten your dashcam after nudging it.

Good post. I'm from New York and live in the South and my colleagues are amused when I say "Instawl the sawftware" instead of "instahl the sahftware".
I call it the "slanted A sound" and they speak with the "vertical A sound".

"Pro camerawork"...
Vertical video disagrees...
and it's not a garbage truck, it is a beta of the new snow removal process.

for once vertical video is actually desired.

The way Ender's Game was meant to be played...

Also: a highly appropriate use of vertical video.
