Compressed Natural Gas Animation
Saturday, September 15, 2007

This interesting and excellent video presents a graduation project. I'm not sure which university the students are from, but from the video we know they are Mechanical Engineering students. According to the video description, this project handles the transportation of Natural gas from Sidi krir, Egypt to Vasilikos, Cyprus, utilizing modern technology of compressing the gas "CNG". The project discusses the new concept of using Compressed Natural Gas technology, which lets the gas under the conditions of 250 bars, 25 deg C, and to be shipped to Cyprus by a normal-modified container ship. The Video is created by 3D Max by Ahmed Fathy and Yasser Fathy. For more info contact: yaser.fathy@yahoo.com




Compressed Natural Gas (CNG) is a substitute for gasoline (petrol) or diesel fuel. It is considered to be an environmentally "clean" alternative to those fuels. It is made by compressing natural gas (which is mainly composed by methane (CH4), in a percantage range of 70% to 98%). It is stored and distributed in hard containers, at a normal pressure of 200/220 bars, usually in cylindric of spherical shapes to maintain equal pressure on the walls of the containers.

CNG is cheaper as fuel for our car compared to petrol/gasoline. I wonder when will I use CNG for my car? The biggest obstacles are the cost to install a CNG engine and the lack of petrol station supplying CNG in this country. I hope and pray the cost of CNG engine and its installation can be cheaper as well as to see more petrol station supplying CNG.

The Inner Life of a Cell - Animation
Monday, January 22, 2007

As I browse through Curious Cat sometime before, I came across this interesting article outside of chemical engineering, more towards bio-stuff. It is about the animation of cell inside the out body. "The Inner Life of a Cell, an eight-minute animation created for Harvard biology students… illustrates unseen molecular mechanisms and the ones they trigger, specifically how white blood cells sense and respond to their surroundings and external stimuli." The online video is beautiful, Check out - Cellular Visions: The Inner Life of a Cell

Animation of the inside of a cell

“What we did in some cases, with the full support of the Harvard team, was subtly change the way things work,” Liebler says. “The reality is that all that stuff that’s going on in each cell is so tightly packed together that if we were to put every detail into every shot, you wouldn’t be able to see the forest for the trees or know what you were even looking at. One of the most common things we did, then, was to strip it apart and add space where there isn’t really that much space.”

The video includes a nice musical soundtrack. It would be great to have alternative soundtracks explaining the science behind the animation.

XVIVO also relied heavily on PDB (Protein Data Bank) Reader, another LightWave plug-in well known in the scientific animation community that brings in both the point cloud data and XYZ coordinates for all the atoms in a protein

XVIVO lead animator John Liebler discovered Happy Digital’s HD Instance, what he now refers to as a “magic plug-in for instancing,” for global motions through displacements.
