Getting Started

Prerequisites

• Odin Programming Language
• Visual Studio Code

Building the Project

To build the project, run the following command in the terminal:

odin build . -debug -out:build/debug.exe

Alternatively, you can use the provided VS Code tasks:

Open the Command Palette (Ctrl+Shift+P) and select Tasks: Run Task. Choose Build. Running the Project To run the project, you can use the provided VS Code launch configurations:

Code Overview

Main Components main.odin: Entry point of the application. Initializes the scene and starts the rendering process. camera.odin: Defines the camera and its properties. hittable.odin: Defines the objects that can be hit by rays. interval.odin: Provides utility functions for handling intervals. material.odin: Defines the materials and their properties. utils.odin: Contains utility functions. vector3.odin: Provides vector operations.

Example Code

Here is an example of how materials are added to the scene in main.odin:

material1 := material(dieletric{1.5})
append(&world, Sphere{[3]f32{0, 1, 0}, 1.0, material1})

material2 := material(lambertian{[3]f32{0.4, 0.2, 0.1}})
append(&world, Sphere{[3]f32{-4, 1, 0}, 1.0, material2})

material3 := material(metalic{[3]f32{0.7, 0.6, 0.5}, 0.0})
append(&world, Sphere{[3]f32{4, 1, 0}, 1.0, material3})
