3d position from 2d position

[Spidla]

Is there any way to retreive 3d position from screen 2d position
In CollisionManager are only functions to get scenenode from 2d but I need pure 3d position

That's impossible. Imagine your mouse cursor on a position on the screen. The position on the screen plane is distinct, while the "position" in space could be anywhere on a ray from the interception point of the near clipping plane to the intersection point on the far clipping plane (and beyond, indeed). Thus, the only way to express the "3d position" is a linear equation.

Cheers.

Or, if you mean what your mouse is over.

You could use getRayFromScreenCoordinates and then use that ray in getCollisionPoint.

yes that`s it thanks
