چکیده

This paper introduces a 3D rendering engine that combines rasterization and ray tracing techniques to approximate global illumination in real-time. Namely, direct and indirect diffuse illumination are generated with state of the art illumination techniques processed on the GPU, including a new sky lighting technique that we propose to simulate realistic ambient lighting for outdoor environments. The illumination is then complemented with realistic refl ections and refractions generated by an hybrid real -time ray-tracer that performs the ray tracing step on the CPU and the lighting on the GPU.

Realtime Ray Tracing on GPUS: NVIRT by NVIDIA and RayGLSL by LFK

Currently everyone is speaking about ray tracing. In 1968 rst steps in the elds of Ray Tracing were made. Since then, this topic keeps appearing in the media continuously. However, until now there are only applications in the high quality o ine area. In the real-time sector it has been kept in check consequently by the rasterization algorithm, which current graphics cards are designed for. But ...

Realtime ray tracing and interactive global illumination

One of the most sought-for goals in computer graphics is to generate “realism in real time”, i.e. the generation of realistically looking images at realtime frame rates. Today, virtually all approaches towards realtime rendering use graphics hardware, which is based almost exclusively on triangle rasterization. Unfortunately, though this technology has seen tremendous progress over the last few...

Zusammenfassung Interaktive 3D-Graphik basiert heutzutage fast ausschließlich auf dem Rasterisierungsverfahren, welches aber in Hinblick auf Bildqualität zunehmend an seine Grenzen stößt. Eine Alternative zur Rasterisierung ist das Ray Tracing, welches zwar allgemein für bessere Bildqualität bekannt ist, aufgrund hoher Rechenanforderungen aber bisher im Allgemeinen als unvereinbar mit interakti...

Final Project: Real-Time Global Illumination with Radiance Regression Functions

This is a report for machine learning final project, which combines realistic rendering and machine learning. As is known, global illumination is very challenging for its expensive computing requirement. In general, Monte Carlo ray tracing or Photon Mapping techniques are used in rendering global illumination, which requires several hours or even days to generate a smooth and physically correct...

Interactive Global Illumination using Fast Ray Tracing

Rasterization hardware provides interactive frame rates for rendering dynamic scenes, but lacks the ability of ray tracing required for efficient global illumination simulation. Existing ray tracing based methods yield high quality renderings but are far too slow for interactive use. We present a new parallel global illumination algorithm that perfectly scales, has minimal preprocessing and com...
