Team Meetings - HephaestusVision/hephaestus GitHub Wiki

Journal of Meetings and Decisions

  • 2012-08-29 Wed - Hal and Chris met with Patrick for initial project meeting
  • 2012-08-29 Wed - Hal, Chris, Frank met to organize team.

  • 2012-09-05 Wed - Hal, Chris, Frank, Patrick met. (Chris was late to the meeting.)

    Before Patrick arrived

    • Review differences with C++ and Java

    Once Patrick arrived

    • Discussed User stories and made changes to third user story
    • Discus basics on graphics and polygon options for 3d display

    After Patrick left

    • Mapped out processes: Kinect - Laptop - cloud - server - cloud - device
    • Discussed alternatives and stated that we would look up other options.
    • Discuss jobs over the next few days

    To Do:

    • Hal: Barebones QT + VTK application, put in repository. Check out Midas.
    • Chris: Keep working on kinect with PC, and look for open source sdk. Create a progamatic interface (set of functions and classes) for getting the mesh. from the GUI application.
    • Frank: Write up functional Spec, and get caught up on Git and C++.

  • 2012-09-07 Fri - Hal, Chris, Frank, Prof. Pozefsky

    • Talk about adding a comment section to website
    • Discuss what is necessary items we need to develop on mac (machine and developer profiles)
    • Discuss expanding KiwiViewer for IOS application instead of create one from scratch
    • Decide to ask Patrick to get Midas account and make sure it will run on 7/8 year old machine
    • Discuss options for technology spike (IOS Development or PCL)

  • 2012-09-12 Wed - Hal, Chris, Frank, Patrick

    • Talked about getting a Midas server
    • Patrick seems happy with the functional spec.
    • Discuss applying for jobs at Kitware

  • 2012-09-14 Fri - Hal, Chris, Frank, Prof. Pozefsky

    • Discussed Mac situation. There is one mac at the library. Swain hall has mac computer lab, but need to get Xcode installed.
    • Getting 3 IOS developer licenses under the name Hephaestus
    • Discuss VPN server for Midas
    • Updated platform selection

    After meeting with Pozefsky

    • Created schedule for the project.
    • Discuss what changes would be applied to KiwiViewer

  • 2012-09-21 Fri -Chris, Frank, Prof. Pozefsky

    • The department set up a blade for Midas, the computer is a 64bit Ubuntu computer and does not have much memory. If this is a problem we need to speak with Pozefsky.
    • There is a Mac our group (any other groups) can use in Sitterson 234.
    • Discussed architecture diagram.
    • Decided that one technology spike was getting Chris getting the kinect to work with the computer.
    • A good option for the next spike would be creating a n IOS app that can communicate with a server.
    • Discussed the possibility of having a clean break between the OpenCV model and the VTK file to possible be able to switch to a different file format (from OpenCV to another format).
    • Decided to get rid of 3rd user story
    • Need to organize schedule in a table.

  • 2012-09-26 Weds - Chris, Hal, Frank, Patrick

    • Showed Patrick VTK file of Chris' laptop station
    • Patrick recommended having a way for the computer app to tell the user when they are done collecting point. For example, when the points match the original points a pop up appears telling the user that they are done.
    • Chris needs to check the cloudy class and camera class to make sure they make sense and can be used by kinect data
    • Hal will be gone from October 14-21 (the same week as Fall break)

  • 2012-09-28 Fri - Chris, Hal, Frank, Prof. Pozefsky

    • Mac in 234 is available now. They are putting the newest xcode on it
    • If need help with mac, email [email protected] and cc Bill Hayes
    • We will present Midas for technology talk on Oct. 31
    • On the computer app, we should have a label on each side of the window. One saying model and the other saying camera.
    • Do we want the model and camera views to be equal sizes? Way to make middle bar dragable with changeable real-estate.
    • Email pointers to cmake and git to Billy Hayes.
  • 2012-10-3 Weds - Chris, Hal, Frank, Patrick
    • Showed the demo to Patrick
    • Contemplated re-sizing the live camera to make it better reveal show what the kinect sees. (maybe make it wider)
    • Patrick recommended to reset the camera on start-up of the computer application
    • Patrick showed us another website for Midas. midas3.kitware.com/midas
    • set up git bug tracking
  • 2012-10-5 Fri - Prof. Pozefsky, Chris, Hal, Frank
