Texture

Texture[obj]

is a graphics directive that specifies that obj should be used as a texture on faces of polygons and other filled graphics objects.

Texture[obj,map]

specifies the projection mapping map to assign to vertices of 3D graphics objects.

Details

  • Texture mapping is also know as UV mapping or diffuse mapping.
  • Texture is typically used in modeling to project an image to a 2D polygon or 3D surface.
  • Texture can be used in both Graphics and Graphics3D.
  • In Texture[obj,…], the object obj can be an image, a graphics or arrays of colors.
  • The following forms can be used to explicitly specify the color values for textures:
  • Texture[{c1,c2,…}]a 1D texture of colors
    Texture[{{c11,c12,…},…}]a 2D texture of colors
    Texture[{{{c111,c112,…},…},…}]a 3D texture of colors
  • Each color can be either a list of the form {r,g,b} corresponding to RGBColor[r,g,b] or a list of the form {r,g,b,a} corresponding to RGBColor[r,g,b,a].
  • Texture[obj] is equivalent to Texture[Rasterize[obj]] and will rasterize obj at the size and resolution it would normally be displayed in a notebook.
  • Texture[obj,map] provides a texture obj that can be applied to faces of polygons and surfaces by assigning coordinates to vertices from the projection mapping map.
  • Possible 3D projection mappings for 2D images include:
  • Automaticautomatically choose the projection
    Noneno projection
    "Box"box projection
    "Cubic"cubic projection
    "Cylindrical"cylindrical projection
    "Front"planar project on the x–y plane
    "Planar"planar projection
    "Spherical"spherical projection
  • VertexTextureCoordinates can be used to specify a projection mapping for a given graphics primitive.
  • Opacity can be used with Texture to specify overall opacity of textures.
  • Texture can be used in FaceForm to texture front and back faces differently.
  • The colors in Texture are taken to be diffuse colors in their interaction with Lighting.
