In computer-based modelling or graphic simulation: each of an array of hexahedral (usually cubic) elements that collectively constitute a representation of a three-dimensional space or image, each representing a single unit of volume.

1976 Proc. Symp. Computer-aided Diagnosis Med. Images in 3rd Internat. Conf. Pattern Recognition (IEEE Computer Soc.) 28/1 We denote the gray level associated with the hyper-voxel H(i,j,k,t) by I(i,j,k,t). The physical meaning of this is that the gray level of the voxel (i,j,k) at time t is I(i,j,k,t).
1994 Sci. Amer. Mar. 82/1 Volume graphics software..stores the entire model in memory as a collection of ‘voxels’ (volume elements akin to pixels), then draws a screen image by casting imaginary rays from behind the model.
2013 Custom PC Mar. 90/2 Back in the days when PC hardware would strain to even load a word processor, voxels gave us long draw distances and pinpoint precision for sniping.
