LVectorBase::EnumVertices
#include "ltwrappr.h"
virtual L_INT LVectorBase::EnumVertices(L_UINT32 dwFlags=0)
L_UINT32 dwFlags; |
/* flags that determine which object's flags to enumerate */ |
Enumerates all vertices within the vector handle.
Parameter |
Description |
|
dwFlags |
Flags that determine which object's vertices to enumerate. Possible values are: |
|
|
Value |
Meaning |
|
0 |
Enumerate the vertices of all objects. |
|
VECTOR_FLAGS_SELECTED_ONLY |
Enumerate the vertices of selected objects only. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
This function will enumerate all the vertices in the given vector.
Note: In DirectX, you cannot enumerate vertices, therefore this function will do nothing.
