Modeling an Arco floor lamp by Castiglioni in Blender 3D
A very good practice that I always recommend to my students is to model pieces of furniture in your spare time. Every time I have a few time available I open up Blender 3D and start to work on some furniture models. If you do that for a while, I a few weeks you will have a great set of models to use in your projects. Today I will show how to model great piece of design furniture, which is the Castiglioni Arco floor lamp. This is a very elegant and modern lamp that appears today in a lot of interior design projects, especially at the living room.
Well, the first thing we have to do before start to model this object is find some reference images, which you can find with the help of Google. Save an image with a side view of the Arco lamp and place it as the background of the 3D View in Blender. To show the modeling process in a faster way, I have created a timelapse video, with the full modeling and the rendering created in LuxRender.

As you can see by the video, the modeling of an Arco Lamp requires only the traditional poly modeling tools of Blender, which are the extrude and spin basically. Something that I always do to work with curved models, create a reference object and subdivide it to find a middle point. It makes the alignment of the 3D Cursor to the center of rotation of the arc a lot easier.
The base of the lamp requires a bit of extra work, because of a hole at the object. Since this part doesn’t show up much and it’s almost all the time hidden by a sofa or other piece of furniture.
This is the final result of model rendered in LuxRender for about an hour.

The studio setup really helps with the glossy reflections from the metal parts of the Arco Lamp.
Well, if you want to check out the model here is the Arco floor lamp file to download.

While the background image is quick and easy, I’ve found a far more robust method of using a reference image is to create a UV mapped reference plane.
Add a new plane, UV map the reference image to the whole of the plane. Then the trick is to add a material to the plane using the image as a texture and UV for the mapping.
The image will appear distorted on the plane (unless it was square to begin with) but simply typing alt-v in object mode with the plane selected will scale its aspect ratio to the image. Now you have a reference plane which can be rotated, translated, and scaled to make modeling easier.
[...] I always have a studio setup scene ready to show models created in Blender 3D, to render them in either YafaRay or LuxRender. If you are a regular reader of the blog, you might have seen one of those scenes used to present a furniture tutorial showed here in the past, like this modeling tutorial about an Arco Floor Lamp.

As always, fantastic. Thanks, Allan.
I will follow your tip about modelling our furniture.
