Realtime glossy reflections
|
Hi there, i just want to show some of the realtime indirect lighting experiments we made using light propagation volumes. It is a pretty cool technique where you inject some light into a volume texture and the propagates it a couple of times using sp... |

CUDA real time ray tracing tutorial
|
We have made a simple and comprehendable tutorial on how to implement an ray tracer in CUDA.
Read the tutorial and download sourcecode and demo here:
http://cg.alexandra.dk/
It consist of only two files and it should be easy to jump... |

GPU raycasting
|
I have been playing with some GPU raycasting on my nvidida 8800 gtx card.
Its a pretty cool volume rendering technique, that can render advanced
effects like the ray marching algortihm and refraction in realtime.
But the purpose of my imple... |

Cuda Smoke Visualization

Just made this nice image, with our new real-time Cuda based raytracing prototype.
It is nowhere near finished but i thought it looked cool so why not post.
The program enables the user to navigate inside the particiapating media and adjust many vi... |

3d points to convex polygon
|
Hi there i have a question.
I have generated a number of coplanar points, by slicing a cube. And i want
to render these point using opengl POLYGON.
But how do i make sure that the points are oriented correctly, clockwise or anticlockwise?
I'm h... |

Waterboy!!

Hii guys, we are back with another Open gl project, Waterboy!!
This is a realtime watersimulation, that solves the Kass shallow water equations, by Jacobi iteration.. If that dosents make sense just try it out,
we think it is pretty cool, especiall... |

Pressure boy!!

Hi folks.
This is an project we made for the physics simulation course at the university.
I wrapped the project up in some executables to finish the whole thing.
The idea is to simulate inflated objects physically, and interactivly play with the... |

Looks pretty neat.
Would it be faster than simply blurring cube mapped targets?
Hi well you cannot compare cube mapping with this, because the light interacts both ways, as you can see on the statue. There is... |

Dungeon Fortress - First Impressions

Wow amazing
I really like these kinds of dungeoncrawlers. I guess when you are a small team the procedural generation of every game asset is really the way to go. good luck and looking forward to seeing the result.

Light Propagation Volumes and SH questions

Thanks for a great thread with a lot of useful info on LPV. So to follow the trend i also tried to implement this technique, and after some struggle i finally got something on the screen.
Its not anywhere finished yet, but i wanted to test... |

I really dig this!
Even though i am struggling with 3d graphics all day long, my all time favorite game is 2d scrollers!
Thanks! |

Real-Time Fragment Shader Voxels
|
It is nothing fancy just some good ol ray casting.
I made a tutorial that describes the technique.

Ja jeg sidder i Århus og lege med voxels :-)

Looks interesting!
I really like voxel rendering and been playing with it for some time, i use it in my drilling simulator to represent bone that can be drilled away.

Hi guys thanks for the comments
to Chris : about Optix we are looking forward to that
to Astrofa : No wonder it runs a little jerky because the tutorial dosent use any accelration structure. This is because it is a tutorial and i wanted the cod... |

Hey Master, you are really a one man coding army!!
It is very impressive and especially your water and the sky rendering amaze me.
I understand that you use the Preetham sky model, do you upload to a cube or spherical map? I am really interest... |

Cuda Smoke Visualization

Thanks for all the replies.
Just to make things clear, this is a visualization tool and it does not simulate the density field(smoke). But several smoke data set can be loaded and can be viewed in an animation.
