int GsSetView2 (
GsVIEW2 *pv
)
|
Arguments
| pv |
Pointer to viewpoint position information (matrix type) |
Return Value
0 is returned if the viewpoint was successfully set, otherwise, 1 is returned.
Explanation
The World Screen (WS) matrix is directly set from the viewpoint information
pointed to by pv.
When GsSetRefView2() is used to determine
the WS matrix from the viewpoint, errors may occur when the viewpoint is
moved due to insufficient precision in the operation. For this reason it
is usually better to use GsSetView2(). GsSetView2() should
be called each frame if the GsRVIEW2
member super is set to anything other than WORLD. In this case,
the viewpoint will move if the parameters of the parent coordinate system
change even if the other viewpoint parameters have not changed.
If GsIDMATRIX2 is used as
the base matrix, then the aspect ratio of the screen will be adjusted automatically.
