MineCraft - Real-time Path Traced I suppose everyone has played MineCraft by now. :) So have I, and I was wondering how MineCraft would look if you would keep the data, but replaced the renderer. These screen shots have been generated using a stochastic ray tracer / path tracer,...

Outbound - Real Time Ray Tracing These screenshots are taken from 'Outbound', a game based on the real-time ray tracer 'Arauna'. The blurb, from the project page: "Harrold C. Babbage, grandchild of Charles Babbage, the father of the first idea of a programmable computer, has...

Excercises in Optimization This is a screenshot of a small RTS that my students had to optimize, as a final assignment for the 'PR3' course of the mADE/IGAD program (http://igad.nhtv.nl/made). IGAD is a 4-year program that teaches students to become game developers. PR3 is a f...

Raytraced Pinball Game This is a screenshot from the game 'Time of Light', which was developed by students of IGAD (International Game Architecture & Design), which is a 4-year program that prepares students for the game industry. Time of Light has been developed using...

Raytracing and Global Illumination This is an image from my real-time ray tracer, Arauna. Over the past monts, I have been working with Roel Reijerse to add global illumination to it. We implemented a sort of a 'static irradiance cache': As a preprocessing step, a fixed set of points...

Ray Tracing pretty image contest These images where rendered by ray tracers built by second-year students of our IGAD course ('International Game Architectue & Design'), for the Graphics Programming course. The final assignment for this course was to write a ray tracer in C++, with...

Image of the day People, I have a small comment on the IOTD mechanism: Today, an iotd that I posted four days ago was added to the gallery along with 5 others. This is not ideal. I suspect that most people primarily check the three images on the front pa...

Arauna Real-time Ray Tracing These are some screenshots from my real-time ray tracer, Arauna. I have presented this ray tracer this week at the RT07 conference on real-time ray tracing in Ulm, Germany. A download link for the demo, its source code, accompanying paper and th...

MineCraft - Real-time Path Traced I was thinking about doing that per tile as well, definitely makes sense. I'm not sure if I want to take this beyond raw rendering, but if I do I will consider that.. Let me know if you want to take my code and add the gameplay, I would be more than...

Ray tracer performance Ah but that CPU doesn't even have SSE2... In that case you can't even compile Arauna yourself; it has tons of hand-written SSE2 code. Sorry about that. Then again, your CPU is ancient, you should be grateful it still works. ;)

Ray tracer performance Arauna doesn't use a GPU at all. 800x800 @ 30fps would require (depending on the scene) a quadcore processor, ideally an i7. With one of those that performance level is not too hard to reach. Brigade does use the GPU, but it's a path tracer...

Ray tracer performance Check this forum: http://ompf.org/forum . It's all about ray tracing, with an emphasis on real-time. Quite some ompf members lurk on GameDev too btw. Shameless plug: Check my real-time ray tracer, Arauna: http://igad.nhtv.nl/~bikker . Th...

KD-Tree traversal (traytracing) am I missing a case? Hm, I'm not a C++ expert, so someone will probably correct me, but here we go: If you have only a small recursive function, then you are doing tons of function calls compared to the actual work load. A function call is not 'free': a stack fra...

KD-Tree traversal (traytracing) am I missing a case? Are you trying to figure out how to traverse a kD-tree yourself? You may want to check out Wald's work, or Vlastimil Havran's thesis. They both provide tiny algorithms for kD-tree traversal. Yours is too complex. On a sidenote: Implement your own...
