Engineering Research Apprenticeship
Program at UL
•An undergraduate scholarship that provides hands-on,
collaborative research experience with professors.
•Each student is assigned to work under a professor
based on an interest form the student filled out.
•To continue in program, each student must maintain a
3.5 GPA and give one presentation a year or have
research published.
My assignment: UL
office at LITE
(Louisiana
Immersive
Technologies
Enterprise)
What is our project?
To create an interactive mobile
application of the University of
Louisiana at Lafayette’s campus.
*Including current campus and
future additions through the Master
Plan (25 year plan for remodels and
additions at UL).
Project audience: Students of UL and
prospective students wishing to tour
campus
Take This…
And Make It This!
AND Even This!
Overall Progress
Modeled the campus buildings using
computer aided design software
Autodesk Maya
Implemented into Unity (the game
engine which the app runs)
Added interactive features
Creating the Campus Buildings
Goal: Model and texture each building
using the least number of polygons
possible
Began with “heavy” architectural
models.
Original architectural model of Our
Lady of Wisdom
Remodeled for lowest polygon count while still
retaining overall look
To create this elliptical
dome, a cylinder with 20
divisions was rotated and
scaled to match the shape
of the original model but
without as many faces.

Remodeled
President’s House:
Original face count-69,865
Remodeled face count-28,810
Original vertices count-100,668
Remodeled vertices count-44,009
Texturing
Technique: UV Mapping
UV mapping is the 3D modeling process of making a 2D
image representation of a 3D model.

Take this and assign
to each face of a
polygon then scale to
realistic size.

Implementing into Unity
Unity is a tool for video game
development, architectural
visualizations, and interactive media
installations.
The layout of the campus in the game
engine matches exactly to the
physical layout of the university.
Research Park-Contains buildings in
app that do not physically exist yet.

Interactive Features
Graphical user interface which can detect taps on a touchscreen device.

Future Project Plans
Add more aesthitcs including
greenery, cars, students, the swamp,
etc.
GPS capabilities with quickest route
to class option
Goal: Make as realistic as possible.
Entertainment Plans: Create games
with campus
-Ex: Cajun Pepper Run: Navigate
through campus as a student trying to
collect as many peppers as possible.
-Ex: Hide and Seek with a baby alligator
What is augmented Reality?
•Virtual reality replaces the world with a simulated one, but
augmented reality supplements real-world environments with
computer-generated sensory.
•Camera and sensors in a smartphone or tablet allow augmented
reality to add layers of digital information directly on top of items
in the world around.

How does this apply to our project?
•We paired the game engine Unity with the augmented reality
software platform Vuforia.
•The software platform Vuforia, specifically for Android and IOS,
allows mobile applications to recognize images from a Vuforia target
database.
•We chose a detailed picture to upload to the Vuforia database.
•Vuforia uses algorithms to detect and track features that are found
in the image. Simplistically, a pixel map of the image is created.
•In Unity, this image was set as our target, and all virtual content
was placed on top of it .
• When the image target is recognized by the iPad camera and
sensors, the app supplements the real world image with the added
computer generated content based on the pixel map.
Choosing a Target Image
•Image targets are images that Vuforia
can detect and track.
•The target must be rich in detail, have
good contrast, and cannot have any
repetitive patterns. Otherwise, the camera
and sensors of the iPad would not be able
to distinguish from different parts of the
pixel map.
Poor image choice due
to repetitive patterns
Example of a Good Image Target
An image uploaded to
the Vuforia Target
Database.

features that Vuforia uses to
detect the image target.
