|
hrPrev |
HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) | |
|
aLine1 |
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 |
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 |
Returns the intersection point of aLine1 and aLine2. |
