Howdy,I need to draw a handle on a polygon object' point, but where the point is on the HyperNURBS surface. I looked in the SDK Documentation for the SDSObject class, and there is a function TransformPoint() but it only says "Dummy function. Always returns FALSE."
So, how do you get a polygon object's point position on the HyperNURBS surface?
Adios,

I would also like to know. I asked this question about 2 years ago already and it was told that it´s not possible to get the unsubdivided point on the subdivided HN surface (well, you could project the point yourself with a ray, but that´s not very efficient).
So if it is possible I am also highly interested in knowing this.

Hm. Must be possible some way, because the Isoline Editing mode in Cinema does exactly that. Unfortunately, I also don't know how to do that. The function
LineObject* GetIsoparm(void)
should have something to do with it...Greetings,

The isoparm should have nothing to do with the subdivided point relations of an unsubdivided and subdivided mesh. It´s not even sure to be there (if the object doesn´t incorporate the isoparm it´s not there).
Check my old thread for what I mean and want.

Hi,
is PolygonObject* GetSDSMesh(BaseObject* op) not what you are looking for?
You get a PolygonObject which returns the polygonized object where you can get the point positions.
Bye.

Howdy,
AHA! Thank you Shawni. That works! The first points in the SDS mesh's points array correspond to the points in the cage's points array.
Adios,

Good to know about that point order in the SDS mesh. One day I'll need that, too.

GetSDSMesh unfortunately doesn´t seem to work in GetVirtualObjects() as there are no caches and this returns the polygon object of the caches. That is the initial problem.

CSTO on a SDS object returns a polygon object with the iso cage points at their original point indices. The additional points of the subdivision are listed after the iso cage points.

And that is supposed to work in GetVirtualobjects Matthias? Hmm, I must try this again.

Howdy,
OK, it seems GetSDSMesh() doesn't work from TagData::Execute() either.
CSTO works, but I've only tested it when the polygon mesh is a direct child of the HyperNURBS object. How do you match up a single polygon mesh to the correct index in the "result" AtomArray when there's more than one polygon mesh under a Null, under the HN?
Adios,
