Point

Updated In 7 Graphic
Point[coords]
is a graphics primitive that represents a point.
Point[{coords1, coords2, ...}]
represents a collection of points.
  • The coordinates can be given either in the ordinary form {x, y} or {x, y, z} or in scaled form Scaled[{x, y}] or Scaled[{x, y, z}].  »
  • Offset can be used to specify coordinates in two dimensions.  »
  • Points are rendered if possible as circular regions. Their diameters can be specified using the graphics directive PointSize.
  • Point diameters are not accounted for in hidden surface elimination for three-dimensional graphics.
  • The option VertexColors->{c1, c2, ...} can be used to specify colors for a collection of points.
  • In 3D, the option VertexNormals->{n1, n2, ...} can be used to specify effective normals for a collection of points, to be used to determine colors of points from lighting.
  • Individual coordinates and lists of coordinates in points can be Dynamic objects.
