Problem description

In this homework, you will

1. decimate meshes to a smaller number of triangles,
2. render suggestive contours to help illustrate their shape, and
3. implement an additional feature of your choosing.

There are several slots in need of your code, which are marked clearly and explained in the homework document.

To run the viewer, type:

./bin/viewer ./models/horse.off 

at the command line, where './models/horse.off' is the model you wish to use.

Setup

Disclaimer

The setup process is the exactly same with the previous homework. You can reuse the library files you previously installed. Create lib directory and move all library files to there, or change the paths written on config.cmake.in file.

You can work on either corn machines, or on your personal machines. If you use your own machines, c++ complier and cmake must be installed. The code is tested on the corn machines, which use the following versions:

• g++ (ver. 4.8.2)
• cmake (ver. 2.8.12)

Install Libraries

The following libraries are required:

• Freeglut: For rendering. Tested with ver. 2.8.1.
• OpenMesh: For general mesh processing. Tested with ver. 4.1.
• Eigen: For numerical computation using vectors/matrices. Tested with ver. 3.2.6.

GLUT is already installed on corn machines and Mac OS X system, so you can skip installing Freeglut if you use them.

For Ubuntu users, we recommend to install Freeglut using apt-get:

sudo apt-get install freeglut3-dev

Windows users need to download and install Freeglut manually from the link above.

For the rest of libraries, if you use Unix (Linux or Mac OS X), run the following script file.

./install_libraries.sh

This will create lib directory and install libraries in this directory.

If you use Windows or the script file above has some problems, you can also manually download and install the libraries. In this case, you may need to change the library directories written in config.cmake.in file.

Please contact to CA if you have any problem installing libraries.

Compile code

If you use Unix (Linux or Mac OS X), run the following script file.

./install.sh

This will create build directory and compile code. The output binary file will be created in bin directory. After the initial installation, you don't need to run install.sh again, but just run make in build directory.

You can also compile code using CMake yourself. Please take a look at CMakeLists.txt and install.sh files for details.

Submit your code

First create your own README file that gives the names of your group members and an index to your program files and functions. Please compress the entire directory except library files into one file, name it as cs348a-hw4-(group_member_names), and send it to the following email address.

[email protected]

Please include [cs348a-hw4] in the subject of your email, and make a clear note about collaboration in README.

For any question, please contact to CA.
