Cheng Lor Desk Scene
 Mystery Desk 
Inspiration

My inspiration came from mystery novels.  I wanted to create a desk that tells the story of a detective working late trying to solve a mystery, but also include objects that have me in it too.  To achieve the mystery side of my scene I have include objects that a detective would have on his desk, such as a hat, a mug, a magnifying glass, cigarettes, pencils, paper works, and a gun to protect himself from danger.  On the other hand, to represent myself in the scene, I included objects that show my interest in music, mathematics, art, and computer graphics.  The posters on the wall show two bands that I like the most at performing and composing rock music, (Linkin Park and Metallica).  The calculator on the desk shows my interest in mathematics, especially calculus.  The sketch drawing of a face represents my interest in art, because I like to draw human figures.  Lastly, the monitor’s screen shows my interest in computer graphics by displaying a computer-generated scene of a serpent trying to eat a mermaid. 

To give my scene a moody look, I have included three light sources, the room light, the outside light, and the lamplight.  The outside light was use to help cast shadows of the window blinds onto the surfaces in my scene.  The room light was use to balance out the light that was coming from outside, and lastly, the lamp light was use for directing our eyes to the desk.  In addition, I also have different colors for each light source.  The outside light is yellow, the room light is orange, and the lamplight is white. 

In my scene, all the objects are created using the primitive shapes in Lightwave, and then multiplying it and modifying it by using tools such as bevel, extrude, lathe, resizing, rotate, and stretch.  Lastly, all my surfaces that has an image on it was done using UV mapping, and the rest were presets of texture from Lightwave.

Problems and Solutions

One of the main problems that I had when creating my scene was setting an image onto the surface of my objects, and making it look right in layout.  I started out by applying an image onto the object using the Surface Editor.  But, what I notice was wrong when using this technique to was that whenever I move the object in layout, the image on my object’s surface moves too, and I see a repetition of the image on the surface.  Trying to solve this problem, I used Texture Editor to adjust the scale, position, rotation, and falloff, but it didn’t work, the image surface of my object still moved when I move my object.  After searching on the internet, I found out that the solution to the problem was “UV mapping.”  So I tried it out, and figure out that with UV mapping I could apply an image onto the surface of my object, and that image would stay on that surface without changing, when I move the object in layout.  Without UV mapping the image applied to the surface would be considered a texture, and that’s why I see a repetition of the image when I move the object in layout.  So, UV mapping was the solution to applying an image onto a surface permanently.
