Dear Prospective Employer,

Let me take this opportunity to introduce myself and seek your assistance in
finding suitable employment. I am a graduate student specializing CAAD
(Computer- Aided Architectural Design) in the School of Architecture at The
Ohio State University, Columbus, Ohio. This is a unique program with a focus on
the exploration of electronic / computer media which may create a better
architecture. My course work at The Ohio State University involves many
computer science courses and CAAD courses.

I have been actively involved in developing CAD software for architectural
design/drafting applications, under the able guidance of Dr. Chris Yessios for
the past three years. I am very familiar with solid modeling systems and
graphic packages ( Actually I have developed my own solid/void modeling system.
So I am very proud of my knowledge about CAD and programming in C). I have
demonstrated skills in graphics programming on the Macintosh and Sun work
station (UNIX) environments. Currently I am working on a Masters thesis project
which will result in the development of a CAAD system with solid modeling/
geometric reasoning capabilities.

Furtheremore, since I have diverse and unique academic background, I believe
that the uniqueness is going to help develop unique and creative CAD/ other
systems (I also have many ideas about CAD applications).

I am about to complete my Master's program. So I am deeply interested in
pursuing a career in your company. I firmly believe your company could benefit
from my expertise and solid background in CAD and solid modeling fields.

I would greatly appreciate if you could point me to the person(s) responsible
for hiring me, so I can discuss my interests in working with you. I hope I can
get a letter from you as soon as possible or I can be reached at the above
phone numbers. Thank you.

P.S.: 1. Application program available upon request.
      2. Will send code segments if requested.



Sincerely yours,

Jinwon Choi.

------------------------------------------------------------------------------
CAAD RELEVANT PROGRAMMING EXPERIENCE

2D Drafting Operations and Extrusion Operations:
          Operations for generating two dimensional primitive objects. Curve
          Operations. 2D Boolean Operations(Union, Intersection and Difference)
          Operations for generating 3D primitive objects by extruding 2D
          primitives. Wall Generating Operations.
Editing Operations:
          Geometrical and Topological Editing. Rotation, Scale, Copy and Move
          Operations at all hierachical levels. Insertions and deletions at all
          hierarchical levels. Insert point, insert segment, insert face,
          delete point, delete segment, delete face.  The hierarchy is point,
          segment(line), curve(lower level of polygon), face(higher level of
          polygon), volume(lower level of object), and object(highe level of
          object) in turn.
Color and Texture Operations:
          Color rendering and Textures Generaion. Color Scanning Operation by
          scan line algorithm. Sorted Color Rendering. Back Face Removal and
          Hidden Line Operation. Paint color on face and object. Vector-Based
          Textures Generation. Basic patterns, stones,bricks, and concrete
          patterns.
Revolutions and Reformations:
          Rotational and Axial Sweep Operations. Animated Reformation. The
          Reformation is a transformation where the shape of one volume changes
          to the shape of another.
View Control and Management:
          Projections, Auxiliary views, and Perspective view generation.
          Zooming and Panning. Automated View Animations along with a path.
          Controlling reference planes. View Clipping.

          Dynamic Memory Allocation.
Shadow Generation:
          Shadow Generation of objects. The operations deal with specific solar
          time data. The data include month, day, time, and latitude. Shadow
          animation. Output data about solar geometry and some evaluation
          results.
Void Modeling Techniques:
          The generation and editing of skeletons of two dimensional void
          models. A void model is distinct from a solid model because it
          specifies the enclosed space through the skeleton. On the basis of
          the two dimensional void model three dimensional solid models of the
          spaces and the enclosures can be generated, so called building
          models.
