Both the word “pixel” and the word “voxel” are commonly used in both of these different senses. I believe the word “voxel” was created to be explicitly a 3D analog of a 2D “pixel”. For example, you can also have “pixel art”, drawings made up of little squares, which only loosely have to do with pixels as samples for a raster image or physical camera detector elements or physical display elements. https://en.wikipedia.org/wiki/Pixel_art https://en.wikipedia.org/wiki/Pixel_art
