The big difference that separates 3DCoat from other sculpting programs is that instead of using only polygonal meshes, it can also use voxels.<\/p>\n\n\n\n
What are Voxels<\/a>:<\/strong>\u00a0Voxels are volumetric pixels, like a 3D equivalent of pixels.<\/p>\n\n\n\n When you sculpt Voxels tools operates over volume and allows you to sculpt without any topological constraints and make complex details from nothing. You can change the topology as you wish. The default voxels density is very different in printing and in 3DCoat because printing works with mm and there are 5 voxels\/mm by default, in 3DCoat we have 1 voxel\/mm by default.<\/p>\n<\/blockquote>\n\n\n\n Voxels are better for organic modeling and the initial blocking out phase while the Surface mode is better for hard surface modeling since it’s a lot easier to retain hard edges while manipulating your model.<\/p>\n\n\n\n There are a variety of tools and methods you can use in Voxel mode, which, as long as you keep your voxel layer at a reasonably high resolution and avoid operations that apply automatic smoothing, will allow you to create some pretty nice hard surface models using voxels.<\/p>\n\n\n\n Working with voxels we have faceting on the model surface because voxels do not have surface normals which allow the viewport smoothing you see in Surface mode and all 3d applications. <\/blockquote>\n\n\n\n
This approach gives you an absolute feeling of freedom in sculpting. It is not based on surface deformation but on volume building and filling.<\/p>\n\n\n\n\n

Voxels are just volumetric cubes or pixels in 3d space so we need to subdivide the geometry<\/a>.<\/p>\n<\/blockquote>\n\n\n\n
