The pick point does give you local coordinates relative to the picked object. If the tranform above the picked object is identity, it will be the same as virtual world coordinates. Sounds more like you want to convert mouse coordinates to screen coordinates. If that's the case, you don't need to pick; use getPixelLocationInImagePlate() from the Canvas3D. If you want that position in the virtual world, transform it by the transform returned by getImagePlateToVworld(). -- Mark Hood =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
