Enumerates all vertices within the vector handle.
#include "ltwrappr.h"
virtual L_INT LVectorBase::EnumVertices(dwFlags=0)
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. |
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
This function will enumerate all the vertices in the given vector.
Note: In DirectX, you cannot enumerate vertices, therefore this function will do nothing.
