Detailed Description

MeshViz Property node that defines a color mapping with interpolated color in each interval.

This node defines a linear color mapping defined by a set of scalar values and their corresponding colors. For a given value v, Vk <= v <= Vk+1, the associated color c is determined by a linear interpolation between (Vk,Ck) and (Vk+1,Ck+1). Where Vk,Ck is pair number k of the colormap.

Notes:

  • The number of colors must be exactly the same as the number of scalars.
  • If either the number of scalars or the number of colors is zero, the color mapping is ignored.
  • Values less than the first scalar are assigned the first color.
  • Values greater than the last value are assigned the last color.
