Overview
This project was done for the course TSBK07 - Computer Graphics at LIU. The project is a path tracer with multiple scenes which showcases its power. There are diffuse, reflective and transmissive materials, all seen in scene 0. The path tracer has also been optimised to be able to handle a large amount of polygons, as seen in scene 3, where the stanford bunny with tens of thousands of triangles is rendered in real time on computers with somewhat decent hardware. Due to course restrictions, a library written by ingemar Ragnemalm was used instead of glm. The project was done together with Ludwig Boge.
Features
- Real time Path Tracing: Real time path tracing utilizing the GPU and with BVH-trees to render large scale models at high frame rate.
Technologies Used
-
C++ and OpenGL: the path tracing itself runs in a GLSL fragment shader.
-
VectorUtils4: glm-like header file library which was mandatory for the course, otherwise glm would have been used.
