Digital sculpting

Organic volume, gradual relief, and local surface changes shaped by pushing, pulling, and smoothing are likely visual cues.

Visual traits

• Organic or sculptural continuous volume
• A combination of smoothed surfaces and localized relief
• Form adjusted at scales from broad masses to fine detail

Expected changes

• Three-dimensional forms are more likely to have organic or hand-shaped continuous volume
• Local buildup, carving, and smoothing changes are more likely to appear on surfaces
• Geometry is more likely to feel shaped from masses than assembled from rigid parts

Definition

Digital sculpting creates form by using brush-like operations to push, carve, and smooth the volume, relief, and detail of a 3D mesh. It is distinct from clay-looking materials, physical sculpture, and rendering that produces a finished image.

In more detail

Digital sculpting shapes a three-dimensional form sculpturally through repeated brush operations such as pushing, carving, smoothing, and pulling. It is well suited to adjusting organic volume, soft relief, and local surface detail, but it does not determine the subject, surface material, lighting, or final image style. Clay-like rendering, physical sculptural media, high polygon density alone, and two-dimensional shaded drawing are separate concerns.

Includes

• Directly deforming the volume or surface of a 3D mesh with brush-like operations
• Sculptural 3D form making through operations such as building up, carving, and smoothing

Excludes

• Materials or rendering that make an image look like clay, stone, or metal
• The medium, production history, or display format of a physical sculpture
• Operations that paint shading or relief into a 2D image without constructing geometry

What this does not imply

• A particular material such as clay, carved stone, or metal
• A particular subject, character, work genre, or composition
• High polygon density, realism, a renderer, or a final output format

Variability

The appearance of relief and brush marks varies with geometry density, brush settings, post-processing, materials, lighting, and generation model, so visible sculpting marks are not guaranteed.

Usage

• Use the atomic expression as a 3D geometry method without adding a material such as clay
• Use the diagnostic expression only when sculptural operations and volume need emphasis

Distinguish similar expressions

• Specify material or appearance when only a clay-like surface is wanted, without changing the geometry
• Specify a rendering method when the requested result concerns image finishing through light or reflection calculation

Typical uses

• Specify a person, animal, creature, or other organic form as sculptural 3D geometry
• Request 3D geometry refined from broad volume to surface detail

Possible failure modes

• Adding only a clay-like material without changing the volume or surface geometry
• Showing relief only through two-dimensional shading rather than constructed 3D form
• Treating render realism or high polygon density as sculpting itself
