# View inside the room

I used Cuboid to build 4 walls and make them composed like a room, the codes and result as followings.

My question is that is it possible to move the viewpoint to inside the room? The thing I want to do is making users feel themselves are inside the room, and they can rotate the screen to see what the room look like from the inside. Is it possible?

wallChosenColor = LightGray;
WallThick = 10;
roomLength = 10;
roomWidth = 5;
roomHeight = 2.5;
floorChosenColor = White;

Room3D = {
EdgeForm[],
Specularity[White, 50],

(*Walls*)
FaceForm[wallChosenColor],
Cuboid[{{-WallThick/100, -WallThick/100,
0}, {roomLength + WallThick/100, 0, roomHeight}}],
Cuboid[{{roomLength, -WallThick/100,
0}, {roomLength + WallThick/100, roomWidth + WallThick/100,
roomHeight}}],
Cuboid[{{-WallThick/100, roomWidth,
0}, {roomLength + WallThick/100, roomWidth + WallThick/100,
roomHeight}}],
Cuboid[{{-WallThick/100, -WallThick/100, 0}, {0,
roomWidth + WallThick/100, roomHeight}}],

(*Floor*)
Opacity[1],
FaceForm[floorChosenColor],
Cuboid[{0, 0, 0}, {roomLength, roomWidth, 0}]

};

Graphics3D[{Room3D}
, ViewPoint -> {-3, -2, 1}
, ImageSize -> {400, 400}, Lighting -> "Neutral"]


• I gave a tentative answer. It's not clear to me how you want the user to look around the room. – Michael E2 Dec 4 '14 at 22:39

Put the ViewPoint inside the room:
Graphics3D[{Room3D}, ViewPoint -> {-3, -2, 1}/15,

• @Chien-ChingVincentHsu From the docs for ViewPoint: "The view point is given in a special scaled coordinate system in which the longest side of the bounding box has length 1. The center of the bounding box is taken to have coordinates {0,0,0}". Dividing by 15 simply put the ViewPoint near {0,0,0}. ViewVector will be a better choice for some applications (see Rahul's link), since it uses the coordinate system of the graphics. There are other View* options to consider, too. – Michael E2 Dec 5 '14 at 14:29
