Appearance specifies the visual properties of geometry by containing the Material, ImageTexture/MovieTexture/PixelTexture, FillProperties, LineProperties, programmable shader nodes (ComposedShader, PackagedShader, ProgramShader) and TextureTransform nodes.

The Appearance node belongs to the Shape component and requires at least level 1, its default container field is appearance. It is available since VRML 2.0 and from X3D version 3.0 or higher.

SFNode [in, out] metadata NULL [X3DMetadataObject]

Information about this node can be contained in a MetadataBoolean, MetadataDouble, MetadataFloat, MetadataInteger, MetadataString or MetadataSet node.


SFString [in, out] alphaMode “AUTO” [“AUTO”|”OPAQUE”|”MASK”|”BLEND”]

Provides options for control of alpha transparency handling for textures. AUTO means Material transparency is applied to texture transparency for full backwards compatility with X3D3, OPAQUE means ignore alpha transparency to render texture as opaque, MASK means alpha-testing of pixels as fully transparent when alpha value is less than alphaCutoff and fully opaque when alpha value is greater than or equal to alphaCutoff, BLEND combines partial transparency of textures and materials.


SFFloat [in, out] alphaCutoff 0.5 [0,1]

Threshold value used for pixel rendering either transparent or opaque, used when alphaMode=”MASK”.


SFNode [in, out] acousticProperties NULL [AcousticProperties]

Single contained acousticProperties node that can specify additional acoustic attributes applied to associated surface geometry.

SFNode [in, out] pointProperties NULL [PointProperties]

Single contained PointProperties node that can specify additional visual attributes applied to corresponding point geometry.

SFNode [in, out] lineProperties NULL [LineProperties]

Single contained LineProperties node that can specify additional visual attributes applied to corresponding line geometry.

SFNode [in, out] fillProperties NULL [FillProperties]

Single contained FillProperties node that can specify additional visual attributes applied to polygonal areas of corresponding geometry, on top of whatever other appearance is already defined.

SFNode [in, out] material NULL [X3DMaterialNode]

Single contained Material node that can specify visual attributes for lighting response (color types, transparency, etc.) applied to corresponding geometry.


  • If material is NULL or unspecified, lighting is off (all lights ignored) for this Shape and unlit object color is (1, 1, 1).

SFNode [in, out] backMaterial NULL [X3DOneSidedMaterialNode]

Input/Output field backMaterial.

SFNode [in, out] texture NULL [X3DTextureNode]

Single contained texture node (ImageTexture, MovieTexture, PixelTexture, MultiTexture) that maps image(s) to surface geometry.


SFNode [in, out] textureTransform NULL [X3DTextureTransformNode]

Single contained TextureTransform node that defines 2D transformation applied to texture coordinates.


  • Texture coordinates are reapplied (or else recomputed if textureTransform field initially NULL) whenever the corresponding vertex-based geometry changes.
  • If textureTransform array is empty, then this field has no effect.

MFNode [in, out] shaders [ ] [X3DShaderNode]

Zero or more contained programmable shader nodes (ComposedShader, PackagedShader, ProgramShader) that specify, in order of preference, author-programmed rendering characteristics.


SFNode [in, out] blendMode NULL [BlendMode] non standard

Single contained BlendMode node that defines blend mode properties.

SFNode [in, out] depthMode NULL [DepthMode] non standard

Single contained DepthMode node that defines depth mode properties.
