Racer Engine

A ray tracing engine developed in c++, with real time preview and edit using openGL and ImGUI.

Create for practice.

Development documentation:

5. Emissive objects instead of point lights

In action preview:

4. 3D Model loading and rendering

In action preview:

3. GUI window for adjusting data

2. Real-time preview then rendering

Real-time preview	Rendered Image

In action preview:

1. Simple spheres ray tracing:

Rendering an image given a file with spheres positions (Position, Scale, Color, Reflection properties), lights and camera properties.

TODO list and improvements:

• Correct reflection.
• Seperate files and create application structue.
• More seperation files and create application structue.
• Add more complex shapes.
• Implement OBJ importing with materials.
• Replace the input file to be in a JSON formula.
• Use OpenGL to live show effects.
• Use ImGUI to make changes in scene.
• Use ImGizmos to actively manipulate the scene.
• Introduce threading to the project.
• Try to use graphics card in accelerating.
• Commenting.
• Styling using google sheets.
