Java-Applet on Voxel Graphics Dr. Harm Fesefeldt Java-Applet on Voxel Graphics Dasselbe nochmal, mit grossem Bild (nur für schnelleRechner) A voxel is an approximation of volume, much in the same way a pixel is an approximation for area. Imagine a voxel as a cube in space, it has length, width and depth. Just pixels have a fixed length and width, voxels have a fixed length, width, and depth.
