Inferno Pathtracer

Inferno is a CPU-Only, progressive, unidirectional pathtracing engine written in C++.

Features

• Supports OBJ Files
• Supports many material properties
• Uses multiple types of acceleration structures
• Fully capable GUI adds many runtime customizations to the scene and render settings
• Custom threadpool for best performance

Build Instructions

git clone https://github.com/plane000/inferno
cd inferno
mkdir build
cd build
cmake ..
make

Examples

There are many example scenes that I have made already. Just modify the CurrentTest variable inside the CMakeLists.txt to the name of the file you wish to demo.

Basic Scene

The basic use of the API is demonstrated below. More documentation will come once the project is more mature.

#include "../src/inferno.hpp"

static const int width = 1000;
static const int height = 1000;

int main(int argc, char** argv) {
      InfernoEngine inferno;

      inferno.SetMode(MODE_OPERATION_PROGRESSIVE_GUI);

      inferno.InitWindow(width, height);
    
      Scene* scene = new Scene(width, height);
      scene->sky = new SolidColourSky({ 0.0f, 0.0f, 0.0f } 0.0f);
      scene->camera = new Camera(width, height);
	
      // Light
      Sphere light({ 35.0f, 56.0f, 25.0f }, 35.0f, new Material({ 1.0f, 1.0f, 1.0f }, 0.0f, 5.0f));
      scene->objects.push_back(&light);
	
      Sphere sphere({ 0.0f, 0.0f, -8.0f }, 1.0f, new Material({ 0.817f, 0.374, 0.574 }, 0.5f));
      scene->objects.push_back(&sphere);

      Plane plane({ 0.0f,-1.0f, 0.0f }, { 0.0f, -1.0f, 0.0f }, new Material({ 0.9f, 0.9f, 0.9f }, 0.0f));
      scene->objects.push_back(&plane);

      inferno.SetScene(scene);

      inferno.Ready();
      inferno.Render();

      return 0;
}
