Real Time Virtual Planets
|
These images are real-time screenshots of the Geist3D graphics engine. The surface features are generated procedurally down to 1.5m resolution. Each planet maintains the laws of rigid body physics and allows avatars to travel seamlessly between any t... |

Real Time Virtual Worlds
|
These screenshots are from the latest version of Geist3D. The demo consists of a very large environment which contains two procedural planets as well as few avatars, vehicles, a shuttle, a space station and of course, stargates. The graphics engine s... |

Presorting cube vertices.
|
Hi,
I am trying to presort the vertices of a cube using different index buffers so that I can draw alpha blended billboards at each vertex without first having to sort the vertices on the CPU each frame. The idea is to choose n sorting vect... |

Looking for 3D artists
|
I am looking for artists who would like to contribute 3D space models/vehicles/characters to Pangea. This trailer on youtube will give you an idea about the state of the engine.
The goal is to build commercial games eventually. At this poin... |

This is a screenshots of the real time Geist3D graphics engine which we are using for an independent game development project called Pangea. The most distinct feature of the game is a huge environment supporting seamless travel between any two points... |

Deferred lighting and AA, once again
|
I am looking for some advice on how to progress with deferred lighting and especially on how to deal with antialiasing. I know this has been discussed in length on the forums here but I was wondering if someone could put me at ease. I... |

Attaching Camera/Weapons to a character

Hi,
I am trying to figure out the best way to attach a weapon and a camera to an md5 skeletal character animation. I am already running the animation and have a camera attached to the head bone. The walking animation is connected to the “w” key... |

Shader Improvements
|
Hi,
I am curious to see if anyone has some input on this shader for modeling tree leafs. Patches of leafs are made up of textured billboards that always face the viewer. The only input to the shader is vertex attributes containing the... |

Color image histogram equalization

I hope this isn't too much off topic but I was wondering if anyone can point out a good method for histogram equalization of Landsat7 color images. I am building a terrain rendering engine for the west coast of Canada and I am now in the process of m... |

How to meet the right people ?
|
Hi,
I am struggling with how to get in touch with game publishers and developers. I have been working on this new graphics engine for six years now, day and night while working on a Ph.D. It has powerful capabilities such as a real time... |

Presorting cube vertices.
|
Simplifying the problem just made it a lot clearer to me as well. Are you sure though that you have to multiply the 2D solution by the number of faces? It's seems that some of the vectors apply to two faces. I think the problem reduces to 2 vectors p... |

Real time procedural planets

Quote:
8,000 ~= 2^13, and 18,000 ~= 2^14, so 1 m precision fits in a 16 bit integer, with room to spare. It certainly fits in a 32-bit float, which is why I perform my noise generation on the GPU for starfall.
Ok I see, that makes sense. I... |

One thing I meant to try but never did was rendering the planet with z-write disabled. Is that how you're doing it?
Something like that; I am actually rendering the entire scene three times with different frustums for far, medium and nea... |

In the main screenshot, all of the details (mountains/trenches) seem to run vertical/horizontal. i.e. they're at 90º to each other.
Now that you mention it, I notice it myslelf. Probably just a matter of playing with the noise function...... |

Deferred lighting and AA, once again
|
Ok, I will take a serious look at MSAA and run some test. Do you know off any examples in OpenGL off the top of your head? I am assuming if DX10 has the ability to read back individual subsamples from MSAA render targets, then so does OpenGL. |

Deferred lighting and AA, once again

Isn't supersampling where you render the scene into a larger buffer and then downsample? I guess this would be easy enough to try. I could just shrink a screenshot using photoshop. I am curious if this approach would produce better results than the e... |

Deferred lighting and AA, once again

I just had a look at that link and I think that I get the idea! You still have to render the geometry twice, but nevertheless its an ingenious idea. If I understand right then you only render the normals and depth into one FBO first; i.e. e... |

Attaching Camera/Weapons to a character

If I just change the camera orientation, then the weapon will not stay in front of me. Just imagine you are holding a gun and then turn your head. You will not be pointing at anything anymore. It seems like the solution would either have to involve I... |

Looks really good, but it would look even better if an graphics artist would make some textures and building, etc.
