# Path-tracer-using-OpenGL
A path tracer made using OpenGL with decent UI. This path tracing works with non-polygon graphics, which means that all distance calculations are based on the position and direction of the ray.
For those who wants to run this project I have built the project and added it to this repository in the "Executable/" folder.
Features
* 3 different types of object - Cube, Sphere and Plane
* 3 types of materials - Rougth - Metalic, Lens, Light source (emissive material)
* Depth Of Field effect
* Accumulation of previous frames to denoise the image
* You can load any images you want for the skybox (.png or .hdr)
Controls
* W, A, S, D, left Shift and Space - Move the camera
* Mouse - Rotate the camera
* E - Disable or Enable the camera movement
* R - Disable or Enable the Render mode
* F - Hide or Display the User Interface
* T - Make a screenshot of the scene
