Optix-PathTracing
Implementation of path tracing using CUDA and Optix
Motivation
The implementation is my own personal project, I am quiete inrested in computer graphics and I heard about the technique of raytracing in games so I tried to give it a shot. After a few months of learnig about it i finally tried it and made a CPU ray tracing program. When i tried adding some more complex geometry i ran into a bottle neck so i began to learn CUDA in hopes that I could speed up my program and after rewriting the whole thing in CUDA I found out about Optix. It took the implementation to a much higher level than before with the addition of Geometry accel. structs. Now I still make changes from time to time but I am more intrested in learnig more about real time rendering and Vulkan (January 2021)
Instalation
Open the project int the SDK directory with Cmake, chose a directory for build and run. You will have to link with GLM, STB and tiny_object_loader
Results
Currently the program can render a variety of objects, you can add fog in the whole scene and you can use different materials form fully diffuse to dielectrics and combinations of them. All objects must be 3D no simple planes if it is a dielectric. There is also a Boca camera effect and Antialiasing.
Examples of rendered images:
