Technically speaking the fact that you use 4 co-ordinates to specify a point in projective geometry has absoluetly nothing to do with it being a 4 dimensional space; it still is (in fact) a three dimensional space because one entire dimension actually represents duplicates ... Basically, a point in space is: ax + by + cz + 1w if you change the co-efficient of w (to d) this represents the point: a/dx+ b/dy + c/dz + 1w The only exception to this rule is when d=0 which represents the three dimensional vector ax + by + cz |
I have no idea what this is...:P
He means not the fourth dimension in the game, but that it looks like its 4rth dimensianal in a 3d world. When I said that gt5 looks as realistic as a car, to people thats saying its 4d graphics.
