Linderdaum Asteroids
|
We would like to present our Asteroids game powered by Linderdaum Engine, that took part "Shoot'em up contest" at GameDev.ru
The demo with the complete source code is available from http://www.linderdaum.com |

Computed tomography data rendering using GPU accelerated raycasting
|
Linderdaum Engine generates images from 3D and 4D computed tomography datasets using the method known as GPU accelerated volume ray casting. It is a straightforward method that utilizes capabilities of modern video cards and is ready for next-generat... |

Direct volume rendering via GPU accelerated raycasting
|
These are a couple of screenshots from Linderdaum Engine volume rendering demo. Our direct volume renderer is implemented using OpenGL and GLSL. Raycasting is done in a fragment program. It can handle:
o 3D and 4D datasets
o nVidia GeForce... |

Volumetric and polygonal rendering together
|
Linderdaum Engine (http://www.linderdaum.com) has this possibility. Ask at their forum if you have particular questions. |

How do you cast a ray inside a glass material? |

That's really cool. Do you plan on implementing transparency?
We already have one:
Opacity accumulation (without high-frequency transfer functions) is much simpler to implement than quality isosurface... |

ah, I see now! :) that sounds like a pretty good approach indeed. I thought you where doing something similar to this engine; http://www.thermite3d.org
Ahh, they are doing isosurface extraction. We don't. Though o... |

Quote:Original post by _SergeyK_
My framerate heavily depends on the scene (how many voxels are visible) and on which machine (DS/DSi) you run it. But on average I get between 30 and 50 FPS.
The resolution is 256x192 (which is the... |

I can render the same amount of data (models of 256x256x256) on my Nintendo DS using less than 4 MB RAM, no GPU and a ARM9 (67MHz) processor.
But 256x256x256 gives 16 Mb...What did i miss? :O
Btw. in what r... |

What do you mean by that?
Starting from Catalyst driver v9.1 OpenGL 3.0 context can be created and used on any ATI HD card. Starting from HD2400 up to HD4870.
I meant AMD 1x00 series don't support OGL 3. |

On current-gen GPUs with decent pixel shading pipeline you can do a raycasting in a pixel shader. That is pretty straightforward and gives impressive results compared to what can be done in software.
