Voxel data is just a bunch of points, the rendering mechanism makes it no more or less 'voxely'. Ultimately you have some scheme to take your voxel data and turn it into triangles that you can display if your goal is 3d. If you use plain cubes, you will get Minecraft-esque things, at least if you get close enough to the surface. If you use a technique like marching cubes or tetrahedron you can make very fluid or blobby looking things but it is very hard to make a flat surface or a sharp corner. There are methods like dual-contouring which can do both sharp corners and fluid surfaces, but are a more complex, and require combining various densities of voxel data to render fine details. Stitching the voxels of different densities has its own challenges, at least without creating gross artifacts at the edges.
