I still need to add materials to a number of objects. I also need to set up a "mesh light", which will act as the sun when I render the scene in LuxRender. The image here was rendered inside Blender, using an area lamp and ambient occlusion as the light sources. An area lamp is a focused beam of light, seen coming in through the window, while ambient occlusion is a general level of light in the scene, having no direct source, but which exists everywhere and illuminates objects not struck by the area lamp. A combination of area lamps and ambient occlusion is one of the best ways to produce a realistic looking scene in Blender. However, Blender lacks global radiosity, which is the effect of light bouncing off objects in a scene, scattering light and color onto nearby objects. That's why LuxRender is used for the final render, as it has global radiosity capability, and makes for a decidedly better looking scene than what Blender can produce alone.
But there's a cost for such realism: Luxrender can take several days to render a scene, while Blender rendered the above scene in less than a minute.
I also have to put what's called a "portal" outside of the window, which won't actually show up in the scene, but which will help LuxRender to more efficiently direct and calculate the effect of sunlight shining in through the window. The portal is simply a flat plane which tells the LuxRender engine, "Hey, shine a light through this hole in the wall!"
You might want to know, where's the refrigerator? Ummm... it's off camera. Yup, off camera and yet assuredly keeping our beverages and produce nicely chilled. And now I will end this post before you can ask about the microwave oven and dishwasher.
