okay, I have the following code which cycles through the polygons and finds polygons that do not have a partner on the other side of a symmetry plane.> `
\> // Loop through all polygons and see if we need to delete them because they are on the wrong side \> for (lngI=0;lngI<lngPolygonCount;lngI++) \> { \> ///////////////////////////////////////////////////////////////////////////////////////////////////////////// \> // Check to see if polygon has a partner \> lngPartner=FindPolyPartnerTemp(arrPolygons,arrPartnerPoints,lngPolygonCount,lngI); \> \> if (lngPartner==-1) \> { GePrint("Poly Doesn't have a partner "+LongToString(lngI)); \> \> blnOK = false; \> } \>`
The console then prints out a list of indices of polygons that do not have partners.
I would like to then store the points that make up those polygons in an array for future use. Can someone tell me what I need to do to store the points that make up the polygons at the printed indices. eventually I would like to find the coordinates of those points and then determine the average of those points to create new points in between those points.
LOL wordy, I know.. but that's what I am looking to do.. can anyone help me?
Thanks,
~Shawn

The CPolygon class stores four indices into the point Vector array of the object (a, b, c, and d). If the polygon is a triangle, c==d. This does not handle n-gons (5+ point polygons). To get the points of the polygon, make sure you have the Vector array (obj->GetPointW()) and index using the CPolygon element members (for instance) :
Vector v = vadr[arrPolygons[lngI].a];
* Remember that polygons share points so deleting a point in the array will affect all polygons that reference it. See ResizeObject() and VariableChanged for information on changing the number of points/polygons on a Polygon object.
To 'store' the points of interest, I would allocate a BaseSelect. BaseSelect acts like a 'yes'/'no' correlation table for selection. You can Select() the points by index in this class and then use it to retrieve only the points of interest (indirectly by index). See BaseSelect::IsSelected() for the efficient way to traverse the selected elements in the array.

what does "vadr" represent?

Just a variable name used often for easy remembrance.
vadr is the point array. (vector address)
padr is the polygon array. (polygon address)
