Proceedings Article | 21 July 2017 Paper

Real time ray tracing based on shader

JiangHeng Gui, Min Li

Proceedings Volume 10420, 104204F (2017) https://doi.org/10.1117/12.2281945

KEYWORDS: Ray tracing

Read Abstract +

Ray tracing is a rendering algorithm for generating an image through tracing lights into an image plane, it can simulate complicate optical phenomenon like refraction, depth of field and motion blur. Compared with rasterization, ray tracing can achieve more realistic rendering result, however with greater computational cost, simple scene rendering can consume tons of time. With the GPU’s performance improvement and the advent of programmable rendering pipeline, complicated algorithm can also be implemented directly on shader. So, this paper proposes a new method that implement ray tracing directly on fragment shader, mainly include: surface intersection, importance sampling and progressive rendering. With the help of GPU’s powerful throughput capability, it can implement real time rendering of simple scene.
