HDK Version of Carve-Sop

[resonanz]

Hi all!

I am trying to replicate the Carve-Sop on per primitive basis. Digging though the HDK Docs i found cutU and cutV.

My code is as follow:

GEO_Primitive *prim;

GU_PrimNURBSurf *primNurbs;

int ind1, ind2;

prim = gdp->primitives()[0];

primNurbs = (GU_PrimNURBSurf *) prim;

primNurbs->cutU(0, 1, ind1, ind2, 0);

The problem is that nothing happens. The Primitive does not get cut whatever I fill in between the brackets after cutU.

Can someone tell me what I am doing wrong?

Thanks in advance!

What values have you tried for the "keep" input? "If keep is zero the curve is only refined and the indices updated."

Hi Seth, I tried pretty much all combinations I could think about but the result was the same.

Just to make sure:

If I have some Nurbs Surfaces and I would like to cut or lets say carve the surfaces in two pieces, is GU_PrimNURBSurface->cutU and cutV the standard practice or is there a more common approach?

Thanks!
