Ladybug Web Shadow OBJ Core

• To have a core or 'engine' that other scripts may call and use to embed in an iframe
  • Parent scripts can be made with jQuery, Go or whatever
• Everything needed - CSS, HTML and JavaScript - in one small tidy place
  • But will probably eventually go on to also existing as multiple individual JavaScript files

• Loads and displays OBJ and MTL files
  • Calls Three.js loaders based on routines from Ladybug Web 3D Models
  • Loads and makes use of and display texture bitmaps
• Calls Google Maps API > Time Zone APIto determine time zone, date and time information for the selected latitude and longitude
• Calls on Ladybug Web Solar Calculator to perform essential solar calculations
  • Supplies Sun azimuth and altitude given time, latitude and longitude
• Creates 3D plots of analemmas of Sun azimuth and altitude once an hour for all the days of the month.
  • Lines connect each hour on the 21st of the month
  • Midnight highlighted is blue. Noon highlighted in yellow
  • Placards indicate the hour of each analemma
  • Displays current position of sun
  • Displays shadow and shade
  • 3D arrow shows direction of north
• Information panel displays a variety of information including
  • Latitude and longitude
  • Selected time
  • If not top window - ie in an iframe - information panel does not display
• Supports permalinks for the following parameters
  • Only the parameters that need changing need to appear on the location.hash
  • file name
  • latitude
  • longitude
  • year
  • month
  • date
  • hours
  • minutes
  • placeMap.material.opacity
  • project.rotation.x
  • project.rotation.y
  • project.rotation.z
  • project.position.x
  • project.position.y
  • project.position.z
  • project.scale.x
  • project.scale.y
  • project.scale.z
  • cx - camera.position.x
  • cy - camera.position.y
  • cz - camera.position.z
  • tx - controls.target.x
  • ty - controls.target.y
  • tz - controls.target.z

• Small discrepancy with NOAA/Bostock calcs

• Mostapha: Finally, isn't it easier to scale and move sunpath instead of the geometry? I imagine cases that the user input a complex mesh and moving or scaling the geometry will be expensive performance wise.

• Too many minor changes to document easily
• Whole thing seems to be settling down and becoming more stable
• Light intensity to zero if Sun.position.y < 0

• Simplify messaging

• Add messaging system idea

• Add permalink support for groundPlane, analemma, sun intensity
• Add scale project and toggle
• Streamline code

• Add send messages to parent
• Add toggle placeMap visibility
• Set default file to urban model 001
• Improve ability to load files
  • Add cast and receive shadows
  • Add two sides
• Add Edges Helpers to R4 files
• Other bits and bobs

• Add R3
