Volume Pixel (Volume Pixel or Voxel)
Definition - What does Volume Pixel (Volume Pixel or Voxel) mean?
A volumetric pixel (volume pixel or voxel) is the three-dimensional (3D) equivalent of a pixel and the tiniest distinguishable element of a 3D object. It is a volume element that represents a specific grid value in 3D space. However, like pixels, voxels do not contain information about their position in 3D space. Rather, coordinates are inferred based on their designated positions relative to other surrounding voxels. One may compare volume pixels to bricks, which are stacked and used to build bigger structures. In this scenario, each brick is placed next to each other, but the bricks are not defined.
Techopedia explains Volume Pixel (Volume Pixel or Voxel)
Voxels have the ability to contain multiple scalar values (vector data), such as density, opacity, color and volumetric flow rate. Thus, they are used extensively for visualization and analysis of scientific and medical data from devices like CT scanners and x-ray/ultrasound machines. Some game engines also use voxels and volumetric data to create terrain and vegetation.
