　Experience the World in 3D Game

　　Ever wondered how your cat or dog sees theworld? Now you can look through their eyes with the first 3D game thatrecreates the vision of different species based on scientific evidence.

　　The online simulation, created by the French3D design company Dassault Systèmes, with the guidanceof veterinary ophthalmologist (眼科专家)DidierSchmidt-Morand, mimics (模仿)the vision of five animals – cats dogs, rats, hawks and bees – as aplayer steers them through Place Vend洀攀 in Paris.

　　Due to differences in field of view, colourperception and night vision, for example, sight can be drastically differentfrom species to species. "In terms of performance, eyes are as variable asdifferent models of cars," says Schmidt-Morand.

　　The game was created by using existingvirtual models of the square then applying effects based on descriptions ofeach animal's vision. Dassault's 3D software allows a scene to be modified byadding blur or changing the colours, angle of vision and depth of field.

　　Although it was easy to recreate visioninferior to that of humans – cats and dogs, forexample, have trouble distinguishing shades of red –replicating features that we are unable to see was a challenge. Hawks have moredetailed vision than ours, whereas dogs are better at seeing movement and havea wider field of view. "We used virtual cameras to precisely simulatelarger viewing angles but the result made people nauseous(令人作呕的)," says Schmidt-Morand. "So we tweaked(微调) the model to give a sense of the wider view without sticking toreality."

　　The rat's view also departs from reality:because they are near-sighted, everything more than 15 centimetres away is ablur, so they typically move close to walls to help them navigate. "A ratwould never throw itself into the middle of an open area," saysSchmidt-Morand. The simulation for this animal is supplemented with a map inthe top right corner to help determine the rat's position: because of theirlimited eyesight, most landmarks are obscured.

　　The game is intended as an educationalresource and players can discuss their experience with others through communityfeatures on the website. If there is interest from schools and zoos, the teamhopes to recreate the vision of more animals.
