Class ImpNode
See Also: Class ImpInterface, Class INode, Class Matrix3, Class Point3.
class ImpNode
Description:
Import Node class. Methods of this class may be used to set various properties of the node. All methods of this class are implemented by the system.
Sample Code:
The following sample code fragment (from \MAXSDK\SAMPLES\IMPEXP\DXFIMP.CPP) demonstrates the use of many of the methods of this class.
ImpNode *node = iface->CreateNode();
if (node) {
TriObject *tri = CreateNewTriObject();
// Now find the center of the vertices and use that as the pivot
int verts = m->getNumVerts();
Point3 accum(0,0,0);
for(int i = 0; i < verts; ++i)
accum += m->verts[i];
Point3 delta = accum / (float)verts;
for(i = 0; i < verts; ++i)
m->verts[i] -= delta;
tri->mesh = *m;
node->Reference(tri);
Matrix3 tm;
tm.IdentityMatrix();// Reset initial matrix to identity
tm.SetTrans(delta); // Add in the center point
node->SetTransform(0,tm);
iface->AddNodeToScene(node);
node->SetName(_T(n->name));
}
Methods:
Prototype:
virtual RefResult Reference(ObjectHandle obj) = 0;
Remarks:
Sets the object that this node references.
Parameters:
ObjectHandle obj
The object to reference.
Return Value:
One of the following values:
REF_FAIL
The operation failed.
REF_SUCCEED
The operation succeeded.
Prototype:
virtual void SetTransform( TimeValue t, Matrix3 tm ) = 0;
Remarks:
Sets the transformation matrix of the node.
Parameters:
TimeValue t
The time to set the matrix.
Matrix3 tm
The new transformation matrix of the node.
Prototype:
virtual void SetName(const TCHAR *newname) = 0;
Remarks:
Sets the name of the node.
Parameters:
const TCHAR *newname
The new name for the node.
Prototype:
virtual void SetPivot(Point3 p) = 0;
Remarks:
Sets the pivot point of the node.
Parameters:
Point3 p
The pivot point of the node.
Prototype:
virtual INode *GetINode()=0;
Remarks:
Returns the INode pointer for the node.
