1 Color {color [] # exposedField MFColor }
2 Each element of color field contains three floating point number to define the RGB color. Elements are indexed beginning from the 0.
3 Points' colors can be set by Color node, by Material node, or both according to the following rules:
  • If none of them specified, all points are black.
  • If only Material node is specified, the colors in the Material node define the colors of each point.
  • If only Color node is specified, the points are colored according to this node's definition.
  • If both of them are specified, then the Material node's diffuseColor and emissiveColor fields are ignored and Color node's definition is used as a color of points while points are shaded using the overall attributes of the Material node such as transparency.
