void vtkParametricRandomHills::GenerateTheHills | ( | void | ) |
Generate the centers of the hills, their standard deviations and their amplitudes. This function creates a series of vectors representing the u, v coordinates of each hill, its variance in the u, v directions and the amplitude. NOTE: This function must be called whenever any of the parameters are changed.
|
virtual |
Construct a terrain consisting of randomly placed hills on a surface. It is assumed that the function GenerateTheHills() has been executed to build the vectors of coordinates required to generate the point Pt. Pt represents the sum of all the amplitudes over the space. This function performs the mapping , returning it as Pt. It also returns the partial derivatives Du and Dv.
. Then the normal is
.
Implements vtkParametricFunction.
|
virtual |
Calculate a user defined scalar using one or all of uvw, Pt, Duvw. uvw are the parameters with Pt being the the Cartesian point, Duvw are the derivatives of this point with respect to u, v and w. Pt, Duvw are obtained from Evaluate(). This function is only called if the ScalarMode has the value vtkParametricFunctionSource::SCALAR_FUNCTION_DEFINED If the user does not need to calculate a scalar, then the instantiated function should return zero.
