3D model based off a real bookcase. All proportions are correct, and model is correctly sized in centimeters.
Model is mediumly polyed, low enough to render fairly fast, but very close up shots are possible, as every minute detail is modeled.
The materials used are easily changeable, and the height of the shelves can easily be adjusted.
The lower doors are working and rotate on their pivot point to open and close. Model includes drilled holes in wood to attach shelves to, adding to realism.
