Here is an incredible work of the 3d artist named ArcHWiZ that uses Blender and Cycles to show a small living room, along with some nice 3d furniture models. For those artists looking for benchmarks on samples for rendering, a scene like the one created for this project required 3000 samples and 40 minutes to render.
To check more images about this particular project and a high-resolution version, follow this link to the BlenderArtists forums.
Besides the incredible quality of the render, you will also find a small detail that reinforces something that I always say to my students. Even if something looks complex or advanced, regarding modeling, a simple is more than enough to create that “fancy” detail.
Take a look at the stitching details along the sofa, which at some point will make us believe that some advanced 3d modeling technique is in use. And after a brief demonstration from the artist followed by some screenshots, you will realize that it is just a simple extrude and scale transformation.
The high-quality textures and render also helps to give a strong feeling of realism, but with some simple modeling actions, you can get the job done.
