Visualization of brain simulation (87TB dataset)

Bellow a few frames of the video I lead in the context of the Blue Brain project. The full video should soon be available on various channels. Stay tuned.



The video was produced using Brayns, the visualizer I created for visualizing high quality and neuroscience related large datasets.

The rendering technique is of course ray-tracing with a bit of global illumination to enhance the rendering of neuronal activity.


Visiting K Computer in Kobe

Many thanks to my good friend Syoyo for making it possible to visit the K Computer in Kobe. Great time, great people! Inspiring :)

Real-time raytracing of animated nD geometry

Let's face reality, 3D is dead, long live nD. Now that the Sol-R ray-tracer is more or less complete (for what it was initialy designed for anyway), it's time to move on to the next level. I added the Hypercube scene to the Sol-R viewer so that we can now play around with n dimensional hypercubes, thanks to the Delphi code, by cs_Forman (http://codes-sources.commentcamarche.net/source/33735-hypercubes).

Now that it's pretty clear that our world has more than 3 dimensions, I am hoping that Sol-R can now help understanding what n dimensional geometry looks like when it intersects our 3D world.

The code is there:

PS: The code was written while watching the inspiring Christopher Nolan Interstellar movie :-)

Deep learning and neuron visualization

Currently teaching my network to go from a simple representation of a neuron morphology to a more detailed and realistic representation. Here are the first (promising) results:

Global illumination / Volume rendering

Last night, I got inspired by the Exposure Render: An Interactive Photo-Realistic Volume Rendering Framework, and started adding global illumination to volume rendering in Brayns. The first results are the following ones, and the code is about to be merged :-)

When Virtual Drums meet Interactive Brain Visualization

Could not help it, had to synchronize my VDrums with Brayns, the large scale interactive brain visualizer I created at EPFL.


Components used for the demo:
- Mido: http://mido.readthedocs.io/en/latest/ 
- Brayns: https://github.com/BlueBrain/Brayns

In the insideHPC News!

 In this silent video from the Blue Brain Project at SC16, 865 segments from a rodent brain are simulated with isosurfaces generated from Allen Brain Atlas image stacks. The work is derived from the INCITE program’s project entitled: Biophysical Principles of Functional Synaptic Plasticity in the Neocortex.

I produced 2 sequences of that video using Brayns, the application I designed in the context of the Blue Brain Project.
