Height Field Surface

Height Field Surface is a data analysis application which generates a 3D graph for a particular mathematics function. Using a technique called Graphics Rendering Height Plot, an application describes a relationship between lighting and material properties of a given point of a math function on a polygon based surface. Graph images are displayed in 2 different shading models:

  • flat shading
  • smooth shading in a unit cube

For this particular application, a displayed math function is
f(x,y) = 0.13 + 0.5(x^2+y^2)^2 + 0.18 sin(30x+30y) cos(10x-10y)

How do I get set up?
