Scientific Imaging: The Art Of Data

Filed under

Thin orange and blue lines swirl above a surface of colored cones, outlining a hollow cylinder. Suddenly a cluster of red dots gathers in the middle of the cylinder, spinning around furiously and gathering force with each rotation.

The image is abstract, but striking: The red dots, we soon learn, represent a T3 tornado (tornadoes are rated between T1, or "Light Tornadoes," to T10 "Super Tornadoes"); the lines, airflow geometry in and around it. The cones represent wind speed and direction at the ground. The hour-long process of a storm's formation has been depicted in just over a minute. (Click here to see a video of the simulated storm.)

Aided by advances in computer graphics and animation, scientific visualization has grown increasingly sophisticated over the past five years. Forget about those tinker-toy-like atom models from high school chemistry. Nowadays, complex computer-generated images of cell structure and anatomy are used to teach medicine, and computer animations can model everything from melting polar icecaps to protein synthesis. What was once a very traditional field is in the throes of a digital revolution.

It's a booming market, too. According to Machover Associates, a White Plains, N.Y., computer graphics consultancy, the worldwide market for scientific visualization in both two and three dimensions is expected to grow from $10.7 billion in 2005 to $17.2 billion in 2010. Most of the money is going into 3-D imaging, according to Machover, and although the majority of it will come from private industry, a substantial amount of federal research funding will be channeled toward that area as well.

  • A history about Gtk+, Vulkan and Wayland
    A few weeks ago, I was curious to test Gtk+ 4. I know it has some awsome features like OpenGL rendering, major cleanups and other hot stuff, but didn’t have the chance to check it out until then. I was mostly excited about Vulkan. I know both of my laptop’s graphic cards support Vulkan. It’s a hybrid Intel Broadwell G2 + NVidia GeForce 920M, although I don’t use the latter because Linux sucks hard with Dual GPU. Downloaded the latest Gtk+ source, compiled and… nothing. Immediate segmentation fault. Yay! What a great chance to get involved with the next major Gtk+ version development!
  • GNOME Developer On GTK4: State-of-the-Art of Toolkit Support
    GNOME developer Georges Stavracas has shared his thoughts on the state of the GTK4 tool-kit with the recent work involving a Vulkan renderer, including which also now works on Wayland. Georges Stavracas was excited to try the current state of GTK4 development but initially hit a segmentation fault. But after overcoming that, he was successful in running GTK4 on Wayland and the widgets being rendered by Vulkan. He commented on his blog, "May not be as exciting, since there are no new visible features but… damn, it’s Gtk+ being rendered with Vulkan on Wayland. It’s basically the state-of-the-art of toolkit support right now. Even better, the absolute majority of applications will gain this for free once they port to Gtk+ 4 series."
