RayTracing Project

Overview

This project is a simple ray tracing application that renders a 3D scene using the Walnut framework. The application includes a graphical user interface (GUI) for interacting with the rendering settings.

Features

• Ray tracing rendering
• Adjustable rendering settings via GUI
• Real-time updates

Getting Started

Prerequisites

• Visual Studio 2022
• C++17 compatible compiler
• Walnut framework

Building the Project

1. Clone the repository.

2. Open the solution file RayTracing.sln in Visual Studio 2022.

3. Select Release and x64 as your configuration.

4. Build the solution by selecting Build > Build Solution from the menu.

Running the Application

1. After building the solution, run the application by selecting Debug > Start Debugging or pressing F5.

2. The application window will open, displaying the rendered scene and the GUI.

GUI Overview

The GUI is built using the ImGui library and provides controls for interacting with the rendering settings.

Main Components

• Settings Window: This window contains various controls for adjusting the rendering settings.
  • Last Render Time: Displays the time taken for the last render in milliseconds.
  • Render Button: Triggers a new render.
  • Sphere Color: Allows the user to adjust the color of the rendered sphere.

ExampleLayer Class

The ExampleLayer class is responsible for rendering the GUI. It inherits from Walnut::Layer and overrides the OnUIRender method to create the GUI elements.

Renderer Class

The Renderer class handles the actual rendering of the scene. It provides methods for resizing the render target and rendering the scene with different settings.
