# Eleven Renderer

Eleven Renderer is a small basic production oriented open source rendering engine coded in CUDA and C++. It has been made with academic and research purpose so feel free to contribute!

More info about how it works, in my Bachelor's degree (Spanish)

The last release of Eleven Renderer is https://github.com/101001000/tfg-pathtracer/releases/latest

The usage of the program is:

>eleven.exe  <#samples> 

The repo includes couple scenes. For rendering f.e "ClockCC0", move the scene folder to the same path that the executable and type:

>eleven.exe "ClockCC0" 1000 "output.bmp"

You can compile it with Visual Studio 2019, use the MAKEFILE or try one of the releases

The main features implemented are the following ones:

* Texture maps (.bmp)

* HDRI Environment (.hdr)

* Defocus

* Disney BRDF

* Point lights

* Multiple importance sampling (NEE, BRDF, Environment, Pointlights)

* .obj file support (only tri faces)

I did some analysis with Nvidia Nsight Compute. This is the roofline for the ClockCC0 scene.

Please keep in mind this project is in a very early phase.
