示例1: stellate
void stellate (Scene &body, float height)
//
// Adds starlike jags to every facet of the body. The tip
// of a jag is placed in the given height over the center
// of the facet.
//
{
float nx,ny,nz,nk,nn,cx,cy,cz,h;
Vertex* tip;
Facet* f;
int i,j,n;
Scene stella;
for (f = body.TheFacets(); f; f = f->NextFacet() ) {
// calculate the normal form and the center of the facet
f->Normal(nx,ny,nz,nk);
f->Center(cx,cy,cz);
// normalization of the normal vector to unit length
nn = hypot(nx,ny,nz);
// check if facet is degenerate
if (nn == 0) continue;
// add the tip vertex of the jag
h = height / nn;
tip = &stella.AddVertex( cx+h*nx, cy+h*ny, cz+h*nz );
// add three-sided facets for each side of the jag
n = f->GetNumVertices();
for (i = 0, j = n-1; i < n; j = i++) {
Facet& s = stella.AddFacet(3);
s(0) = &stella.AddVertex( *(*f)(j) );
s(1) = &stella.AddVertex( *(*f)(i) );
s(2) = tip;
}
}
// now clear the original
body.Remove();
// and add the stellated body instead (duplicate vertices are now removed)
body.AddScene(stella,Identity);
