Occlusion

Another limitation of natural vision is occlusion. Occlusion is also modeled in the visual perception of the artificial fish (see Fig. gif). An object is ``seen'' if and only if some part of it enters the visual range (or view volume) and it is not fully occluded behind some other opaque object. Implementation details will be described in the next section.
