L_VecPhysicalToLogical

#include "lvkrn.h"

L_LVKRN_API L_INT L_VecPhysicalToLogical(pVector, pDst, pSrc)

const pVECTORHANDLE pVector;	pointer to a vector handle
pVECTORPOINT pDst;	pointer to a VECTORPOINT structure
const L_POINT * pSrc;	pointer to a POINT structure

Converts a Windows 2D POINT into a 3D VECTORPOINT.

Parameter	Description
pVector	Pointer to a vector handle.
pDst	Pointer to a VECTORPOINT structure to be updated with the logical 3 dimensional point converted from the 2 dimensional point in pSrc.
pSrc	Pointer to a POINT structure that contains a 2 dimensional point to be converted into a 3 dimensional point.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

Converts a given 2D physical point into a logical (with X, Y, Z coordinates), 3D point.

The Z value of the destination 3D point will not be changed.

Conversion will be based on the current view port and camera values set in the VECTORHANDLE.

Example

This example will show the 3D point of a given 2D point on the vector drawing.

L_INT VecPhysicalToLogicalExample( 
pVECTORHANDLE pVector, 
POINT* ppt) 
{ 
   L_INT nRet; 
   VECTORPOINT Point; 
   L_TCHAR szBuffer[ 80 ]; 
   Point.z = 0.0; 
   nRet = L_VecPhysicalToLogical( pVector, &Point, ppt ); 
   if (nRet != SUCCESS) 
      return nRet; 
   _stprintf_s( szBuffer,80,TEXT("%f, %f, %f"), Point.x, Point.y, Point.z ); 
   MessageBox( NULL, szBuffer, TEXT("Point"), MB_OK ); 
   return SUCCESS; 
}
