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) https://eprints.ucm.es/id/eprint/68327/1/CALLE%20MONTILLA%2063016_ENRIQUE_DE_LA_CALLE_MONTILLA_Evaluacion_y_aceleracion_del_algoritmo_Path_tracing_en_arquitecturas_heterogeneas_1006096_134067599.pdf
The last release of Eleven Renderer is https://github.com/101001000/tfg-pathtracer/releases/latest
The usage of the program is:
eleven.exe <scene_path> <#samples> <output.bmp>
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.
