[x3dom-users] 2D canvas coordinates to 3D world coordinates

[L. H. <her...@ma...>]

Hi,
I need to calculate world coordinates (X, Y, Z) for different points localized in 2D coordinates (canvas or page coordinates). I do not work with mouse events. Coordinates would be found naturally only in case that at a given 2D point is some geometry (Shape element). It should be something like the inverse function of calcCanvasPos.

Is it appropriate to modify function getViewingRay for this purpose? Or is there other (simple) solution?

Any ideas would be much appreciated.
Thanks
