Eikonal Rendering - Technical Video

ljus (swedish for: light) is an NVidia GPU application, able to simulate the propagation of light through a refractive object, such a glass.
It has recently been part of a research submission accepted at SIGGRAPH.
The video shows the light wavefront first as wireframe (each quad is one calculation unit), then as intensity field, and finally shows how the volume is filled with the light traces (imagine a smoke-filled cube).

If you feel curious and want to know more, take a look at http://www.mpi-inf.mpg.de/resources/EikonalRendering/index.html

And feel free to ask us any questions you have (and we promise to answer ... understandably ;) ).

Cool man! I subscribed to your channel to check for progress ... and contact me if you need help with programming in CUDA or these algorithms here!

hi, these renders are really beautiful. if you check my channel you'll see some a fluid simulator i hope to port this over to for visualization. i like doing multifluid simulations with lots of internal stuff going on, so things like marching cubes aren't enough. i'll tell you if i get anywhere with this.

the gray "plane" coming in from the side is light energy from a point light source, and we simulate how it passes through a glass of wine. :-)

Yes, I did - was hard work, but surely brandnew stuff, and thus easy to be motivated for ;)

What is it you dont understand? :-)

cool;)
