void GetHiddenNgons ( BaseSelect *  sel )

Gets the current hidden N-gon selection.
It has the same order as GetNGonTranslationMap() .

参数
[out] sel Assigned the current hidden N-gon selection.

◆  GetNgonBase()

NgonBase * GetNgonBase ( )

Gets the NgonBase instance for the object.

返回
The N-gon base. The Polygon object owns the pointed NgonBase .

◆  ValidateEdgeSelection() [1/2]

Bool ValidateEdgeSelection ( BaseSelect *  sel )

Deselects all selected edges in sel that are N-gon edges.

参数
[in] sel The selection to check for N-gon edges. The caller owns the pointed BaseSelect .
返回
true if successful, otherwise false .

◆  ValidateEdgeSelection() [2/2]

Bool ValidateEdgeSelection ( )

Deselects all selected edges that are N-gon edges.

返回
true if successful, otherwise false .

◆  GetEdgeSelection()

Bool GetEdgeSelection ( BaseSelect *  sel ,
EDGESELECTIONTYPE   type  
)

Deselects all edges in sel that are N-gon edges as specified by type.

参数
[in] sel The selection to check for N-gon edges. The caller owns the pointed BaseSelect .
[in] type The type of selection to check: EDGESELECTIONTYPE
返回
true if successful, otherwise false .

◆  GetNgonEdgesCompact()

void GetNgonEdgesCompact ( UChar *&  edges )

Retrieves an array that contains N-gon information for each polygon.
若 edges[poly_index] & (1 << edge_index) != 0 the edge is a hidden N-gon edge, where edge_index is between 0 - 3 for quads and 0 , 1 or 3 for triangles.

警告
edges array needs to be freed with DeleteMem() afterwards.
参数
[out] edges Assigned a pointer to the compact N-gon edges array. The caller owns the pointed array.
Neighbor::Init
virtual Bool Init(Int32 pcnt, const CPolygon *vadr, Int32 vcnt, BaseSelect *bs)
