Claim Text:
1. A computer implemented method of interacting with a three dimensional image based lighting surface in order to adjust the lighting properties of the surface, the method comprising: defining an image plane and a user viewpoint for the lighting surface; rendering and displaying on a display of a computer, a three-dimensional scene containing an object in situ within the lighting surface, taking into account said image plane and said user viewpoints; by way of user interaction with the displayed three-dimensional scene, receiving an identification of a selected point on the image plane; tracing a ray from the user viewpoint through the identified selected point on the image plane and either, generating coordinate data representative of a location within a canvas, being a two-dimensional mapping of said lighting surface, of said surface intersection point, and using said coordinate data to adjust, within said canvas, the lighting properties of the lighting surface in the region of the surface intersection point either by and updating in substantially real-time, said three-dimensional scene displayed on said display of said computer using the lighting surface having adjusted lighting properties within the canvas.
