3D-Coat is a commercial digital sculpting program from Pilgway designed to create free-form organic and hard surfaced 3D models from scratch, with tools which enable users to sculpt, add polygonal topology (automatically or manually), create UV maps (automatically or manually), texture the resulting models with natural painting tools, and render static images or animated "turntable" movies.

The program can also be used to modify imported 3D models from a number of commercial 3D software products by means of plugins called Applinks.[1] Imported models can be converted into voxel objects for further refinement and for adding high resolution detail, complete UV unwrapping and mapping, as well as adding textures for displacement, bump maps, specular and diffuse color maps. A live connection to a chosen external 3D application can be established through the Applink pipeline, allowing for the transfer of model and texture information.

3D-Coat specializes in voxel sculpting and polygonal sculpting using dynamic patch tessellation[2] technology and polygonal sculpting tools. It includes "auto-retopology", a proprietary skinning algorithm.[3] With minimal input from the user, this technology generates an accurate and functional polygonal mesh skin over any voxel sculpture, (composed primarily of quadrangles), which is the standard that is widely used in 3D production studios. Normally, this kind of polygonal topology must be painstakingly produced by hand.[citation needed]

  • Texture size up to 16K
  • Ambient occlusion and curvature map calculation
  • Toolset for painting tasks

Digital sculpting[edit]

Voxel (volumetric) sculpting[edit]
