ON_3dPointListRef() [2/4]

ON_3dPointListRef::ON_3dPointListRef

(

const class ON_Mesh *

mesh

)

Description: Construct a point list that references the mesh vertex list. Remarks: If the mesh has double precision vertices, then the point list will refer to them; otherwise, the point list will refer to the single precision vertices.

ON_3dPointListRef::ON_3dPointListRef

(

const class ON_SimpleArray< ON_3dPoint > &

point_array

)

Description: Construct a point list that references the points in a simple array of ON_3dPoint objects.

ON_3dPointListRef() [4/4]

GetPoint()

const class ON_3dPoint& ON_3dPointListRef::GetPoint ( unsigned int  point_index, double  buffer[3]  ) const

inline

Description: Copy point location into buffer and return it as an ON_3dPoint. Parameters: point_index - [in] buffer - [out] If point_index is a valid index, the point coordinates are copied to buffer[]; otherwise the buffer coordinates are set to ON_UNSET_VALUE. You must insure buffer is not null, has proper alignment for storing doubles, and is large enough to store three doubles. Returns: A reference to an ON_3dPoint which is a cast of buffer. Remarks: This is the fastest and most efficient way to get a the location of a point into memory you are managing.
