This is a C++ software raytracer that provides an interactive experience for creating and rendering scenes
Diffuse, metallic, glass and emmisive materials all with texture support and normal maps to enhance the visuals.
Interactive user interface using ImGui for scene setup and control.
Supports loading 3D models in OBJ format using the obj_loader library.
Wireframe and rasterized views for easier editing.
Accelerated ray intersections with bounding volume heirarchies for real time performance.
Saving and loading in json format.
Before you can build and run the raytracer, ensure you have the following dependencies installed:
ImGui: UI library for fast and simple UI.
GLAD: OpenGL loader-generator, OpenGL 3.3 and extensions loading library.
GLFW: Multi-platform library for OpenGL, OpenGL ES, and Vulkan development.
GLM: Mathematics library for graphics software.
OBJ Loader: Library for loading OBJ 3D models.
stb_image: Image loading and saving library.
jsoncpp: Json parsing library for c++.
Upon running the raytracer, a window will open, showing the interactive user interface powered by ImGui. The interface allows you to:
Use the right mouse button and WASD to move and manipulate the camera.
Load 3D models in OBJ format to be included in the raytraced scene.
Click on objects and adjust their properties.
Add or edit existing materials.
Add custom image textures and normal maps.
Control the lighting in the scene.
This raytracer was built with the help of the following fantastic libraries:
ImGui for the interactive user interface. GLAD for OpenGL loading. GLFW for window management and input handling. GLM for mathematics operations. OBJ Loader for loading 3D models in OBJ format. stb_image for image loading and saving. jsoncpp for saving and loading json data
