Abstract
In one embodiment, a method of providing visual feedback to a user in a virtual reality environment is disclosed. The method may comprise: capturing position and depth information of the user using a depth sensor; determining a potential interaction point between the user and a 3D virtual object associated with the virtual reality environment based on the position and depth information of the user; determining, using a virtual depth camera, depth of the 3D virtual object at the potential interaction point; calculating a distance between the user and the 3D virtual object based on the position and depth information of the user and the depth of the 3D virtual object; and rendering a soft shadow of the user on the 3D virtual object based on the distance between the user and the 3D virtual object.
