Voxelator is a free online app that allows users to paint and edit voxel-based models. A voxel is a single point on a three-dimensional grid that is spaced regularly, similar to 3D pixels. Voxel-based graphics have several advantages, including the ability to generate meshes and complex levels at runtime, and that it is easier to create voxel-based 3D models than regular models. Voxelator is a free software and you can choose which license to attach to the models you produce with it, and use them for any purpose -- commercially included (provided you did not use any external resources with limiting licenses).

Mega Voxels is an easy-to-use voxel editor and pixel editor that lets you create 3D pixel art, voxel art and pixel art. You can then share your creations through photos and videos. Connect with friends and share what you make with 3D pixels, voxels and pixels. Explore the community of voxel artists and pixel artists from all levels and share anything you can imagine. Like digital blocks, voxels are used by designers and creators to design all kinds of 3D models such as houses, cars, castles and more. Similar to a 2D pixel, each voxel has a 3D coordinate to define where it is placed in a grid. In addition to its position, voxels are also assigned a color that is displayed when they are added to a grid. Since all voxels are the same size, it makes it incredibly simple to design complex models with ease. When voxels are combined together to create 3D models, it is an art form which is called voxel art.
