#include "ltvkrn.h"

L_LTVKRN_API L_INT L_VecPhysicalToLogical(pVector, pDst, pSrc)

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

Parameters

const pVECTORHANDLE pVector

Pointer to a vector handle.

pVECTORPOINT pDst

Pointer to a VECTORPOINT structure to be updated with the logical 3 dimensional point converted from the 2 dimensional point in pSrc.

const L_POINT * pSrc

Pointer to a POINT structure that contains a 2 dimensional point to be converted into a 3 dimensional point.

Returns

Value Meaning
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.
