Detailed Description

class HUtilitySparseShell
Public Functions
-
HUtilitySparseShell(bool needPairToIndex, bool needIndexToPair)
-
virtual ~HUtilitySparseShell()
-
HC_KEY KInsertShell(int point_count, const HPoint points[], int face_list_length, int const face_list[])
Compacts a sparsely-referenced points array into its minimal subset, records the translation information from the original specification. Requires that a HOOPS segment be open.
- Parameters
point_count – the number of points in the master points list.
points – the master points list.
face_list_length – the length of the face_list array.
face_list – the vertex indices that connect to form faces (see docs for HC_Insert_Shell.
- Returns
the key to the HOOPS shell that was inserted.
-
void DeleteByKey(HC_KEY key)
Calls through to HOOPS to remove the item. If the item was inserted by HUtilitySparseShell::KInsertShell, this function additionally removes the translation information
- Parameters
key – the key to the item to be deleted, as returned from this->KInsertShell.
-
void EditShellPoints(HC_KEY key, int littleIndexOffset, int ndelete, int insert, const HPoint points[])
-
inline void EditShellFaces(HC_KEY key, int ioffset, int ndelete, int insert_list_length, int const insert_list[])
just a simple call through to HC_Edit_Shell_Faces. Nothing needs to be done here, but it provides consistency in the calling conventions.
- Parameters
key – the key to the item to be deleted, as returned from this->KInsertShell.
-
int GetPairCount(int bigIndex) const
returns the number of times vertex bigIndex is shared into littleIndex values
-
bool GetPair(int bigIndex, int n, HC_KEY *key, int *littleIndex) const
retrieves the nth key/littleIndex pair that inherits from bigIndex
- Parameters
bigIndex – the index into the master points array
n – which of the shared vertices to return (e.g. the i in a for(i=0;;i++) loop)
key – returned to user
littleIndex – returned to user
- Returns
true if successful
-
bool GetPairs(int bigIndex, HC_KEY keys[], int littleIndices[]) const
retrieves all key/littleIndex pairs that inherit from bigIndex
- Parameters
bigIndex – the index into the master points array
keys – returned to user. Caller must be allocate to length GetPairCount()
littleIndices – returned to user. Caller must be allocate to length GetPairCount()
- Returns
true if successful
-
bool GetIndex(HC_KEY key, int littleIndex, int *bigIndex) const
returns the bigIndex from which the key/littleIndex pair came
