Ray Tracing Life Science

These three images are screen shots from a movie we've done for professor Patrick C. Fraering at the EPFL in Lausanne, to better understand the functioning and dynamics of the peptide beta amyloid. A hypothesis is that it is the primary cause of Alzh... |

Slicing and dicing a mesh
|
Hi!
I want to slice a mesh so that I have two planes cutting the mesh and only what is between the planes should be visible. Also the interior volume of the mesh must be visible.
I have had a look at opengl clip planes and they are a start... |

Is "Real-Time Rendering, A.-Moller et. al." a good reference?

What's a "Scene Graph"?

I've heard them being mentioned as a way to organize your scenes and I suspect I may have coded one in my engine, but I really don't actually know what they are or what they do.
So - Enlightenment, pleas... |

What about physics? I will need to have localized areas where objects can interact with the terrain. Wouldn't those areas have to be polygonized for the physics system?
Nope, no need as you can as well there shoot... |

I still think you can use a ray-marching approach but limit yourself to a low resolution, then scale this resolution up to fit the rest of your scene (like the tree or players etc...... |

I would love to have a clean solution like ray-tracing but I don't think it is possible for what I'm attempting to achieve. And also the screenshot I showed above has the detail set low in order to make the cracks mo... |

Your username is the answer to all our scientific / computer issues.
That and the triangle.
Hehe :-) It's a nikname I got in high school as I wasn't interested in database programming, only... |

I think I might have came up with an extremely simple solution.
This involves sphere bounded method though. Simple, but if moulded and ingeniously implemented, deep calculus II is avoided.
Lol, a simple thin... |

Why not use the mathematical description (force field) of the landscape directly and raytrace or ray-march it? Your graphical detail would go up a 1000-fold and you could even ma... |

Polygons are so oldschool... ;-)

Option a) is pretty simple so I start with that. If you have objects that number in the hundreds of thousands it makes sense to build an acceleration structure for spatial queries s... |
