// poly-iso surfaces
GU_PrimPoly *polyIsoSurface(float (*ptOutside)(const UT_Vector3 &),
const UT_BoundingBox &bbox,
int xdiv, int ydiv, int zdiv);

I am a bit puzzled how to use this function. It looks like it is the one i need but not sure.

The part that confuses me is

float (*ptOutside)(const UT_Vector3 &)

.
Could it be my array of points/vectors? Would someone from SESI be kind to give me an example pleeeeease… Mark? Edward?Luca?… :roll:
Also is it doing something like this algorithm?

Cheers to any response.

Try this:

static float sphere(const UT_Vector3 &p) { return p.length()-1; }


UT_BoundingBox box;
box.initBounds(-1, -1, -1);
box.enlargeBounds(1, 1, 1);
gdp.polyIsoSurphace(sphere, box, 10, 10, 10);
