RT

A 3D ray-tracing program that renders computer generated images.
A 42 project done with Jeongmo Bae (@jebae), Samuel Boniface (@sabonifa), and Alexandru Moraru (@almoraru).

A scene including 80% of the features in this project.

INSTALLATION

Web Interface

• Install Node.js

RT Program

Run make inside the repo.

$ make path/to/repo

LAUNCHING

RT Program

• The program takes an xml scene file as the input, you can create your own or use the already created scenes.
• Modified files modified and saved are rerendered due to hot-loading implemented in project.

$ ./rtv1 scenes/file_name.xml

Web Interface

• To properly launch the web interface, the following command needs to be executed in the interface directory.

$ node interface/index.js

FEATURES

RT

• 11 Objects: cone, cylinder, plane, sphere, box, ellipsoid, ring, parabaloid, pyramid, rectangle, and triangle.
• Shadows
• Multispot Lighting
• Spherical and directional lighting
• Ambient lighting
• Filters: grey, blur, sepia, and negative
       -> For filter add the following tag to the XML file (but not within the objects tag):
  

      <filter>sepia | grey | negative | blur</filter>

• Cel-shading (cartoon effect)      -> For cel-shading add the following tag to the XML file (but not within the objects tag):
  

      <cel_shading>true | false</cel_shading>

• Translation and rotation (camera and shapes)
• XML parsing and debugging
• Refraction, reflection, and transparency
• Texture mapping
        -> For texture mapping add the following tag to the XML file:
  

      <texture>
        <file>name_of_file</file>
        <reapeat>1</repeat>
      </texture>

• Texture bumping
        -> For texture bumping add the following tag to the XML file:
  

      <bump_map>
        <file>name_of_file</file>
        <reapeat>1</repeat>
      </bump_map>

• Rotation and translation
• Multithread computation
• Hot-loading
• Color

WEB INTERFACE

• Live update of xml file
  

The interface's welcome page.

• Modify camera or add a new object (Note: The modified file will automatically be rerendered due to hot-loading technique implemented in our program.)
  

The interface form for adding a new object to the chosen XML file.
