wishlist: option for zoom, speed, ...

[hainm]

I am myself using VMD for visualization and there are few things I want to customize in in ngl

• camera: orthographic or perspective (I normally use orthographic camera)
• zoom and rotation speed: Most of viewing packages make me feel the molecule is very heavy when rotating. It's great if ngl allows user to config (right now I need to change js file)

I am working on exposing zoom and rotation speed. Would you mind creating a separate issue for the orthographic camera as it requires some more work?

okie. #28

41afbe2 exposes zoom/rotation/pan speed in the GUI via Help > Preferences. I am still streamlining parameter handling for the stage object to allow programmatic access.

Note that preferences are saved locally.

Reworked stage parameter handling some more. The clip/fog parameters are now also exposed. See http://arose.github.io/ngl/ Help > Preferences. There is some documenting work to be done... very shortly:

The NGL.Stage constructor now accepts a parameter object

var stage = new NGL.Stage( "someElementId", {
  rotateSpeed: 4.0,
  fogNear: 100,
  overwritePreferences: true  // otherwise the user preferences take precedence
} );

The stage.preferences object holds user preferences which are stored via localStorage. Call stage.setParameters( { rotateSpeed: 2.0 } ) to change them after object construction.

just tried. Cool.
