ray traced pixel offset mapping

hi
I am working on an new parallax like texture mapping effect, but without the most disadvantages, like height leveling, aliasing and silhouette flattening on large angles to the surface.
This technique implements a volume renderer i... |

Isosurface Terrain

I'm working on a dynamic iso surface rendering technique for xyz-fields for DX9, the geometry is calculated totally on the CPU in realtime for huge fields, so the GPU has time for rendering the actual surface. The data field is sampled bicu... |

ray traced pixel offset mapping

right that was some years ago, my page has moved to www.surface.at with some new stuff, but currently I am kind of busy with my job, I actually used some of this techniques for 'Stoked' an open world snowboard title for the XBox360 with a vast open t... |

just some more detailed information:
The scene is devided and culled by an octree, every node that is small enough to fit in a distance dependent threshold searches for a corresponding Geometry-Buffer in a FILO cache. If there is no matching buffe... |

can you tell something about your SSAO technique, I am working on different approaches but haven't found a reasonable compromise between qualitiy and performance |

Hi,
looks interesting, i did something like this just with depthsprites and postprocessing in the pixelshader for a SPH Fluid simulation. Your refraction looks a bit weird, because of the concretion in the middle of the spheres, it seems that your... |

hi srezic,
there is certainly an assertion in RendererOpenGL.cpp, for debug reason it checks many card and driver capabilities and abort if something is not working, but your card is definitly suitable, so it could be a driver issue, please check... |

it depends. SM 3.0+ and furture cards will have far more pixel shader power, even more with an unified shader architecture, so the question is how to utilise this power to achieve more visual quality.
This demo is just an unoptimzed showcase, in t... |

@Gyrbo: the demo is of course for geforce 7 and up, especially with the soft shadows because of the amount of texture lookups, but there is still room for optimization
@Jnz86: i have never testet it on an ATI, it seems to be that there is an... |

hi anthony,
the errors on the edges are now removed, thanks for the advise.
the center cube just shows the deficiencies of steep parallax mapping, it can't be used on convex geometry because of this flating effect. Normally the surfa... |

there is now a version online with quite performant Soft Self Shadowing:

you can play around with some defines in resource/resources.GravityScript at Line 21
