This is photogrammetry, a real life scan of an actual environment, it creates a model which is ultra realistic and contains all of the small imperfections of real life which man made textures and bump maps cannot achieve.
Ideal for computer games and 3D animations, can be combined easily with other models to create a scene.
The model is of rocks in a garden, lighting is neutral therefore it can be lit with lights to make it appear to be night or any time of the day.
There are a number of formats included for different 3D modeling software, there should be one that is compatible with almost any.
Texture is included, which allows for the OBJ to be re-textured, should you not find the other models compatible with your software, just import and apply the texture.
