Generative Modeling System

Basic System

#define NVPTS 4
#define MAXPTS 2048
Vector3 g[MAXPTS];

int read_curve(void)
{
  int  k = 0;
  while (scanf("%lf %lf %lf\n" ,&(g[k].x),&(g[k].y),&(g[k].z)) != EOF)
    if (k++ > MAXPTS)
      break;
  return k;
}

main(int argc, char **argv)
{
  int nu, nv = NVPTS;
  Poly *tl;
  if (argc == 2)
    nv = atoi(argv[1]);
  nu = read_curve();

  tl = rotsurf(nu, g, nv);
  trilist_write(tl, stdout);
  exit(0);
}

Input-Output

{{-1, 1, 0},  {-1, -1, 0},  {1, 1, 0}},
{{1, -1, 0},  {-1, -1, 0},  {-1, 1, 0}},
{{1, 1, 0},  {1, -1, 0},  {-1, 1, 0}}
}

Extension Options

• Include visualization as 3 orthogonal views (XYZ) and an auxiliary view.

• Include interactive capabilities. The user should be able draw a curve in the auxiliary view and create a surface rotation from it.

• Include curve editing capabilities, such as moving, deleting and adding points. These changes should reflect in the current surface.

• Include surface editing capabilities, such as moving a vertex.

• Include new generative models: Extrude, Twist, Bend, and Taper.

• Include support for a command language integrated with the interactive operations.
