Real-time planet rendering
|
We integrated in our planet renderer our work on vector-based terrain rendering, and the new version of our ocean rendering algorithm. Finally, inspired from Outerra, we also improved the fractal noise details, and added very basic billboard tre... |

Ork: a new object-oriented API on top of OpenGL
|
Ork, for OpenGL Rendering Kernel, provides an object-oriented C++ API on top of OpenGL. Using Ork can greatly simplify the implementation of OpenGL applications. For instance, suppose that you want to draw a mesh in an offscreen framebuffer, wi... |

Real-time Realistic Ocean Lighting

Here are some screenshots of the real-time animated ocean that we recently added to our planet rendering software. The algorithm is described in our paper Real-time Realistic Ocean Lighting using Seamless Transitions from Geometry to BRDF, to appear... |

Real-time Realistic Ocean Lighting (2)

this is another version of our ocean lighting algorithm, using Tessendorf's FFT method to generate the ocean surface. It greatly reduces the repetitive pattern that could be seen with the first version (which was not due to tiling because this versio... |

Real-time Earth-scale terrain editing
|
A recent addition to our planet rendering software, showing real-time out-of-core multi-resolution editing of a terrain dataset made of 6 * 98.304 x 98.304 height samples (i.e., 57.982.058.496 16 bits samples). See the video here. |

this is an update of this post. I added clouds shadows, terrain self shadowing with "Ambient Aperture Lighting", a higher resolution digital elevation model (SRTM v4, 90 meters per pixel on the whole Earth), procedural terrain elevation details,... |

realistic Earth rendering demo

I finally made a demo version of the software I used in this post. If you have enough space and time to download 3.6GB of terrain data, you may try it on your PC (warning: it has only been tested on Windows XP, with an NVIDIA GeForce 7... |

Atmosphere look-up table

I've been thinking about the use of look-up tables to solve the in-scattering integral in atmospheric rendering. In this Gamedev article O'Neil correctly notes that the problem is 4-dimensional. There's the altitud... |

Ork: a new object-oriented API on top of OpenGL

Quote:Original post by samoth
As a little criticism, I noticed that pretty much everything in your library derives from Object, which is a thread-safe reference counted base class.
Which, in general, is probably a good thing, but here I think it... |

Ork: a new object-oriented API on top of OpenGL
|
ok, I see that shared_ptr is now supported in many compilers (this was not the case four years ago when I wrote Ork 1.0). So here is a proposed new API:
- it uses only one ork namespace, without nested namespaces
- Ptr and StaticPtr are r... |

why not use the standard C++ smart pointers like shared_ptr?Even if you decide to stick with your own smart pointer class, consider making it compatible with std::tr1::shared_ptr, a... |

Just out of curiosity: is this the same engine as used for this paper/research work?
Real-time rendering and editing of vector-based terrains
If so, I would be interested to know if this engine can be licensed/b... |

I've been following your exploits over the last year or so and the results are getting ever more impressive.
I do have a question however: where do the changes get stored? Do you have some special method that modif... |

Well done.
Water lighting is really good in the distance - I implemented ocean some month ago and was never happy with how specular/sun reflection looks towards the horizon, it looked to detailled.
Now, I had a qu... |

Great work!
Any chance to know details behind technology used to render terrain in this demo? What is it this? Are there any articles on the web about this technology?
I can give the following details: the te... |

the atmospheric scattering has not changed; But we improved the cloud shader by adapting this article (unfortunately the videos use the old cloud shader) |

Looks very pretty :) I particularlly like the sky's gradient. Is this changeable for day night sequence? Also, that seems like a lot of terrain information, no form of compression?
Good work!
Thanks. The sky can... |
