You may not realize it, but the way you view things is critical to your survival. More specifically, humans and many other organisms see things in 3D. This kind of visual perception allows you to sense danger so that you can calculate a route of escape instantaneously. For example, you can judge how close a car is and then jump out of the way. It sounds like a simple process, but it is highly complex. Experts in visual technology are now making it possible for you to view electronic images in 3D. The question is how they are doing it. In other words, how does 3D technology work?
– The Principle behind It
You have to understand how the human eye works before you can appreciate how 3D technology operates. First, humans have two eyes with a space between them. That is an important point to remember. Each eye captures a slightly different view of a person’s surroundings. Then the brain creates depth as it generates one image from these two views. Stereoscopic vision is the name scientists use to refer to this phenomenon. Similarly, 3D technology produces two distinct images.
Then it sends one image to one eye and the other image to the other eye. That means your eyes are capturing two different images from the electronic source and therefore, your brain creates depth as it processes these images.
– The Principle in Action: Anaglyph Glasses
Anaglyph glasses transmit light in a unique way. Each one of them comes with two lenses. One is red while the other one is cyan. The red lens allows red light to pass through it while the cyan lens allows any color to pass through it except red. That means your eyes would see different images since one lens rests on one eye while the other lens rests on the other eye. Your brain would create depth as it fuses these two images together. Anaglyph glasses are inexpensive and their method of creating 3D images is simple. However, the pictures created in your mind are monochrome and fuzzy. They also make you feel nauseous.
– The Principle in Action: Polarizing Lenses
Light travels as a wave along a particular plane. It can move along this plane in an up-down motion, in a side-to-side motion or both. In this case, you would wear polarizing lenses. Each one would polarize the light in a different way. For example, the right lens would receive light traveling in an up-down motion. The left lens would receive light moving in a side-to-side direction. That means the right and the left eye would receive two different images. Consequently, the brain would create depth as it combines these two images to form one picture. Creating 3D images is also possible through active-shutter and lenticular technology.
– Common Uses of 3D Technology
This advancement is revolutionizing society. For example, movies are now in 3D. Watching such films enhances the feeling that you are a part of what you are seeing. Moreover, 3D technology is taking the gaming world by storm. In fact, almost all video games creators are incorporating it into their latest projects. Architects are also taking advantage of it because they can use it to create an awesome presentation.
The best thing about the world today is that you can record everything that happens in your life. You can even record a road trip from start to finish using a dash cam. This type of camera is necessary for every driver on the road. For instance, how do you support your claims when you get into a car accident? Well, that is simple.

More specially, it has a 160 degrees wide-angle lens. Operating this dash cam is easy. For example, it starts capturing video when you turn on your car’s ignition switch. It stops when you turn it off.
3. The ITrue X3
The resolution on this dash cam is excellent i.e. it has Full HD capabilities with a resolution of 1920 X 1080. It records at 30 frames per second. The wide angle is even better than that of the TaoTronics DVR Dash Cam. More specifically, the ITrue X3 has a wide angle of 179 degrees, which is amazing because it can view your side almost entirely. This dash cam also has an endless looping feature. Moreover, the night vision qualities of the ITrue X3 are exceptional. Another great quality of this dash cam is the sleek design it has making it suitable for high-end cars or for people who just want something classy in their car.
4. The Wheel Witness HD PRO
As the name suggests, this dash cam is a good choice if you are looking at the quality of the video it produces. It has a resolution of 2560 X 1080 or 2306 X 1296. That is the highest resolution available on any dash cam in the market. Another great thing about this camera is that it comes with GPS capabilities.

That is an important feature if teenagers drive your car regularly. To put it differently, you would examine their driving skills and then advise them appropriately.
Facts About Residential Security Drones
Drones are the latest craze in the world of technology. In fact, the market for these gadgets could reach $127 billion in 2020. Currently, it stands at $2 billion annually. People use drones for a variety of reasons. The most common use of it is for military purposes where the US and other governments target terrorists with it.
However, other less controversial uses of this device exist. For example, photographers and filmmakers use it to take aerial photographs. Some companies use it to verify business claims and you can use it to improve your home security. Here are some interesting facts to know about residential security drones.
– They Can Take Pictures of Criminal Activities around Your Home
Many people think of drones as delivery items. For example, Amazon plans to use them to transport packages to their clients. Drones also carry missiles for use in military campaigns. However, residential ones are a bit different. They come with HD cameras that have 720 pixels. Others have either low or high-quality cameras depending on the manufacturer and the price you paid for it. The purpose of these drones is to help you see what is happening around your home. That means you do not have to go outside when you hear strange noises at night. Instead, you can launch your drone and it will help you see what is causing the strange noise.
– They Can Respond To Emergencies Quickly
Responsiveness is critical when it comes to enhancing security. Sometimes, it might take minutes or even hours before anyone responds to your cry for help. It may also take a lot of time before you know what the actual threat is. Residential security drones can weigh anything from 300 grams to 20 kilograms. It all depends on their features and the materials the manufacturer used to make them. That means they can fly quickly to wherever you need them to go. They can also maneuver around buildings and trees among other obstacles without much difficulty. Remember, once a potential robber is likely to run away once he sees a drone following him. You can also send the pictures taken by your drone to the police or the neighborhood watch team.
– They Are Easy To Repair and Operate
A little training is necessary before you operate a plane or install a security system. In contrast, drones are easy to run. In fact, you can operate one after you look at the manual a few times. Additionally, repairing a drone is not difficult because online tutorials on how to repair them exist. Moreover, the sale of drones for recreational use may increase from 1.9 million units in 2016 to 4.3 million units in 2020. This figure indicates that millions of people operate drones as a hobby. You can do it for a greater purpose than that. Get a residential security drone today.
– They Can Carry Emergency Materials
You may need medical attention if someone invades your home. In this case, you would need a first aid kit as soon as possible. Getting this kit to the place it needs to be may be difficult so using a drone to get it there might be helpful. Remember, drones can deliver pizza and books to your house. Therefore, delivering a life-saving pill or an inhaler should be possible.
