Peter Mazen Desk Scene
 Late Night Writing 
Inspiration

Originally I had envisioned a 1700's house of a powerful person who had been up late writing and drinking wine.  Due to time restraints, I had to change my plans, and since I couldn't build the quill pen I wanted, I went with the pencil I already made.  Since they didn't have pencils like that in the 1700's, my scene became an early 1900's house.  Since this house didn't have a room with a desk, the dining table had to be used as one.  Whoever was working had taken a break, but left the lamp on to show the scene.

Problems and Solutions

My biggest problem was the lighting.  I had a lot of glass in the scene, so getting test renders wasn't really a possibility since it took too long.  This problem was compounded by the fact that I haven't done lighting before and didn't know what it would look like after rendered.  I solved my problems by lots of guess and check methods, and a little help from tutorials.  In the end I followed a tutorial almost exactly, and hoped it would work out in the final render.  Lucky for me, it worked out.

My other problem was render time.  It was huge, and far exceeded the time I thought it would take.  If future students read this, make sure to render the day before it is due.  This scene, although fairly simple, took 5 and a half hours to render.  And I forgot to turn anti-aliasing on.  The reason that it took so long to render was the enormous amount of polygons I used, specifically on the glass pieces.  I was unaware how much that would increase the render time, and for the future I will plan the amount of polygons, and will attempt to use as little as possible without ruining the quality.
