void NL3D::CViewport::getRayWithPoint (
|
float x,
|
|
float y,

|
const CFrustum & camFrust ) const
|
|
|
|
Get a 3d ray with a 2d point.
-
Parameters:
-
| x
|
is the x coordinate in the window coordinate system of the 2d point. |
| y
|
is the y coordinate in the window coordinate system of the 2d point. |
| pos
|
gets the position of a 3d point on the ray. It is also the position of the camera |
| dir
|
gets the direction of the ray. The direction is the same than the camera one. It is NOT normalized. |
| camMatrix
|
is the matrix of the camera in use in this viewport. |
| camFrust
|
is the frustum of the camera in use in this viewport. |
