  1. 3D chat with only a webcam

    This application uses only a webcam to generate a psuedo-3d chat with no glasses required...extremely clever.

  2. 3-D photography with Linux

    Plascolin is a nice tool for Linux to create 3-D anaglyph (red-blue) images from two jpeg photographs. However, I couldn't find easy-to-use instructures (for me at least) on the net. Here is how I got it to work on Ubuntu:

    • Install automake: sudo apt-get install automake

    • Look in the /usr/share directory for a directory called automake. Relink all bad links to the appropriate file in /usr/share/automake-xxxx (see your dist) by executing ln -s /usr/share/automake-xxx/file file

    • Install lib gtk+: sudo apt-get install libgtk2.0-dev

    • Install libjpeg: sudo apt-get install libjpeg62-dev

    • Run ./configure to configure the system

    • Run make to make the program

    • Run sudo make install to install it

    • Run plascolin to run it

    After you have taken a set of pictures, rename them from whatever filename the camera saves them as to xxx-l and xxx-r (for the left and right pictures, respectively). You can then use Plascolin to switch back and forth between sets of pictures.

  3. Intel Easy PC Webcam in Ubuntu - Blue Images

    Here's what I did to get the colors to show up correctly (they would be tinted blue).

    In /etc/modprobe.d/options, add:

    • options gspca force_rgb=1

    • options spca50x force_rgb=1
    • options spca5xx force_rgb=1

    I'm really not sure which driver I'm using, so I tried the "shotgun approach" and it seemed to work ok after rebooting the machine.
