Come creare montagne

Esempio: Una Montagne con "height_field" di funzioni:
#declare HF_Res_X = 1024; // number of points in x
#declare HF_Res_Z = 1024; // number of points in z
#declare HF_Function = function{0.1+0.1*sin(x*30)}
#declare HF_Amplitude = 0.5;
height_field{
function HF_Res_X, HF_Res_Z
{ HF_Function(x,0,y) * HF_Amplitude }
//smooth
//water_level 0
texture { pigment{ color rgb<0.6,0.5,1>}
finish { phong 1 phong_size 400
reflection{0.25 metallic}}
} // end of texture
translate< 0,0.001,0>
scale <1,1,1>
}//------------------------------------------------ |
