What does the Mesh do in Augmented Reality?

In augmented reality (AR), a mesh is a digital representation of a physical object or environment. It is made up of a series of interconnected polygons, which are used to create a 3D model of the object or environment.

The mesh is used in AR to overlay digital content onto the physical world in a way that looks realistic and seamless. When an AR application is running, the mesh is used to detect the location and orientation of the device’s camera, and to determine how the digital content should be displayed on the screen.

The mesh can also be used to enable other AR features, such as occlusion (where digital content is hidden behind physical objects) or physics-based interactions (where digital content behaves realistically in the physical world).

Overall, the mesh plays a key role in the AR experience by allowing digital content to be anchored to the physical world and to interact with it in a believable way.

Here is a more detailed explanation of how the mesh is used in augmented reality:

  1. Creating a digital representation of the physical world: In AR, the mesh is used to create a digital representation of a physical object or environment. This is done by mapping the physical object or environment with a series of interconnected polygons, which are used to create a 3D model of the object or environment. The mesh is created by scanning the physical object or environment with sensors, such as a camera or lasers, and then using this data to generate the 3D model.
  2. Overlaying digital content onto the physical world: Once the mesh is created, it can be used to overlay digital content onto the physical world in a way that looks realistic and seamless. When an AR application is running, the mesh is used to detect the location and orientation of the device’s camera, and to determine how the digital content should be displayed on the screen. This allows the digital content to appear as if it is part of the physical world, rather than floating in front of it.
  3. Enabling other AR features: The mesh can also be used to enable other AR features, such as occlusion (where digital content is hidden behind physical objects) or physics-based interactions (where digital content behaves realistically in the physical world). For example, if an AR application is displaying a virtual table on top of a physical one, the mesh can be used to ensure that the virtual table appears to be occluded by the physical one, rather than floating above it.

Overall, the mesh plays a key role in the AR experience by allowing digital content to be anchored to the physical world and to interact with it in a believable way. It is an important part of the AR technology stack, and is used in a wide range of AR applications, including games, education, and industry.

why does virtual reality rely on slightly different views for each eye?

Virtual reality (VR) systems rely on slightly different views for each eye to create the illusion of depth and immersion. This is because the human visual system relies on binocular vision, which involves the use of both eyes to perceive depth and distance.

When you look at an object, each of your eyes sees it from a slightly different angle. Your brain combines these two views to create a sense of depth and distance. VR systems mimic this process by displaying slightly different views to each eye, which allows the brain to perceive depth in the virtual world just as it does in the physical world.

Without this difference in views, the virtual world would appear flat and unrealistic, which would reduce the sense of immersion and make it difficult to navigate. By providing slightly different views to each eye, VR systems are able to create a more realistic and immersive experience.
