Description

hrPrev

HRESULT

HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)

aLine1

TcVnVector4_LREAL&

First line. The first and second element describe the x and y component of a vector collinear to the line. The third and fourth element describe the x and y component of a point on the line.

aLine2

TcVnVector4_LREAL&

Second line. The first and second element describe the x and y component of a vector collinear to the line. The third and fourth element describe the x and y component of a point on the line.

aIntersecPoint

TcVnPoint2_REAL&

Returns the intersection point of aLine1 and aLine2.
