Build Status

Introduction

Sol-R is a CUDA/OpenCL-based realtime ray-tracer compatible with Oculus Rift DK1, Kinect, Razor Hydra and Leap Motion devices. Sol-R was used by the Interactive Molecular Visualiser project (http://www.molecular-visualization.com)

A number of videos can be found on my channel: https://www.youtube.com/user/CyrilleOnDrums

Sol-R was written as a hobby project in order to understand and learn more about CUDA and OpenCL. Most of the code was written at night and during week-ends, meaning that it's probably not the best quality ever ;-)

The idea was to produce a Ray-Tracer that has its own "personality". Most of the code does not rely on any litterature about ray-tracing, but more on a naive approach of what rays could be used for. The idea was not to produce a physically based ray-tracer, but a simple engine that could produce cool images interactively.

Take it for what it is! Sol-R is a lot of fun to play with if you like coding computer generated images.

May the fun continue with your contributions! :-)

Prerequeries

Mandatory

  • CMake 3.5
  • Glew 2.x
  • Glut 3.7
  • Cuda 8.0 or OpenCL 1.2

Optional

  • Kinect SDK 1.8
  • Oculus Rift DK1 SDK 0.2.5
  • Sixense SDK
  • Leap SDK 3.2.0

Build

mkdir Build
cd Build
cmake .. -DCMAKE_PREFIX_PATH=<installation-folder>
make install

Note that the installation process with deploy extra files that are needed by the Sol-R viewer. Typically, textures, environment maps and OpenCL kernels. Therefore, it is required to run the solrViewer application from the installation folder.

Run

<installation-folder>/bin/solrViewer

Selecting CUDA or OpenCL

By default, the OpenCL engine is selected but this can be changed by modifying the SOLR_ENGINE option, using either ccmake or the following cmake option:

cmake .. -DSOLR_ENGINE:STRING=CUDA

Optional dependencies can be activated using the following cmake options:

cmake .. -DSOLR_KINECT_ENABLED=ON -DSOLR_OCULUS_ENABLED=ON -DSOLR_SIXENSE_ENABLED -DSOLR_LEAPMOTION_ENABLED=ON

Supported platforms

Sol-R has currently been tested on:

  • Windows 7 with Visual Studio 2015 Community edition
  • Mac OS X Sierra 10.12.15
  • Ubuntu 16.04
