Abstract
To better explore a virtual 3d computer generated environment comprised of objects which may be voxels, polygons or any other construct are selectively not displayed so as to better reveal underlying objects. The objects are each associated with a metadata value which contributes to determining their visibility such as a density or opacity value. The manner of selection is somewhat analogous to the projection of a beam of light towards the objects from a virtual projector, where a display threshold is determined for each object within the field of view of said virtual projector on the basis of a display function having an inverse relation to distance from the virtual projector and further varying as a function of the angle defined by the orientation of the virtual projector and a line drawn from said virtual projector to each said object respectively. On this basis, objects having a smaller angular separation from the axis of the virtual projector, and closer to the projector, will be preferentially excluded from display.
