Converts a Windows 2D POINT into a 3D VECTORPOINT.
L_LVKRN_API L_INT L_VecPhysicalToLogical(pVector, pDst, pSrc)
Pointer to a vector handle.
Pointer to a VECTORPOINT structure to be updated with the logical 3 dimensional point converted from the 2 dimensional point in pSrc.
Pointer to a POINT structure that contains a 2 dimensional point to be converted into a 3 dimensional point.
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
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.
This example will show the 3D point of a given 2D point on the vector drawing.
