Seasons visualizations using WebGL

These are deployed here: http://stepheneb.github.io/seasons/index.html

To run locally: ruby -run -e httpd . -p 9090 and open http://localhost:9090/index.html

The code for integrating this work as a WISE4 step is located here: wise4/node.

There are rake tasks for generating and locally deploying the WISE4 step version of seasons.

  • rake wise4:generate_step

    generate WISE4 step in: ./wise4/dist/node/seasons

  • rake wise4:copy_step_to_local_vle

    copy WISE4 seasons step to local vle: $CATALINA_HOME/webapps/vlewrapper/vle/node/seasons

The copy_step_to_local_vle task is useful for testing the seasons step if you have a local instance of WISE4 running.

See: https://code.google.com/p/wise4/wiki/StableWISEDeploymentModel

These three Seasons Activities all now support persistence to json:

  1. Investigation 1: What Temperature Patterns Do You See?
  2. Investigation 2: What Is the Shape of Earth's Orbit?
  3. Investigation 3: How Does Earth’s Tilt Affect Temperature?

When any one of these activities are loaded a seasons_activity object is created with toJSON() and fromJSON() methods:

Startup activity and save initial state:

a1 = seasons_activity.toJSON()

Add rows to experiment table, manipulate your view of the Earth and save a new state:

a2 = seasons_activity.toJSON()

Restore initial activity state: the experiment table and graph will be empty and the position of the Earth will be as it was when the visualization first started.

seasons_activity.fromJSON(a1)

Restore second activity state: the experiment table and graph will be filled as before and the position of the Earth will be as it was when the state was saved the second time.

seasons_activity.fromJSON(a2)
