Mesh.

Let's create a mesh by a two-dimensional array of the points lying on a paraboloid:

int x_sz = 20;

int y_sz =20;

SG_POINT* pnts = new SG_POINT[x_sz*y_sz];

for (int i=0;i<x_sz;i++)

for (int j=0;j<y_sz;j++)

{

pnts[i*y_sz+j].x = i-x_sz/2;

pnts[i*y_sz+j].y = j-y_sz/2;

pnts[i*y_sz+j].z = 0.1*(pnts[i*y_sz+j].x*pnts[i*y_sz+j].x+

pnts[i*y_sz+j].y*pnts[i*y_sz+j].y);

}

sgCObject* msh= sgSurfaces::Mesh(x_sz,y_sz,pnts);

delete [] pnts;

sgGetScene()->AttachObject(msh);

msh->SetAttribute(SG_OA_COLOR,30);

msh->SetAttribute(SG_OA_LINE_THICKNESS, 1);
