SDK question 2005-02-03 - By mark wilson
Back
Yeah I know that. What I was actually angling for is the local transform
matrix of the vertex. When you select a vertex, XSI has a local coord
space for it, just wondering if I could get hold of that. I should have
been more clear in my question. To be honest it doesn't really matter
now as I have worked round it, but if anyone knows...

You can retrieve the Geometry object and ask for its vertices:
Geometry can be a NurbCurveList, NurbSurfaceMesh or a PolygonMesh.
>From the CPointRefArray of the SDK doc:
using namespace XSI;
using namespace MATH;
Application app;
Model root = app.GetActiveSceneRoot();
X3DObject myGrid;
root.AddGeometry( L"Grid", L"MeshSurface", L"", myGrid );
Geometry geom = myGrid.GetActivePrimitive().GetGeometry(0);
CPointRefArray points( geom.GetPoints() );
CValue val(points.GetCount());
app.LogMessage( CString(L"Number of points: ") + val.GetAsText() );
for(long i = 0; i < points.GetCount(); ++i)
{
Point pt(points[i]);
CVector3 pos( pt.GetPosition() );
app.LogMessage(
CValue(pos.GetX()).GetAsText() + L"," +
CValue(pos.GetY()).GetAsText() + L"," +
CValue(pos.GetZ()).GetAsText() );
}
