Viewer Configuration

This is a new thread about enhancing the viewer, and allow further options for the camera, grid, axis, etc. All suggestions welcome as well as assistance.

Here are some settings in the viewer that should be configurable:

Camera position (x/y/z), angle (x/y/z), field of view angle
Grid viewable, size, minor/major spacing, and colors
Zoom min and max
Axis viewable, colors
Render smoothing, default color

I've made some changes to the Viewer, moving all settings for camera, grid, axis, zoom, etc to properties withing the object. Everything is now configurable.

I was able to create a very nice view of the OpenJSCAD.org logo from 500 mm above the axis, showing a grid that is 1000mm by 1000mm.

I just added a pull request for changes to both Processor and Viewer. These changes should allow users of OpenJSCAD.org to change the Viewer settings for:

controlling the display of solids
controlling the display of the plate (grid lines)
controlling the display of the XYZ axis
controlling the initial camera position
The Processor also has some improvements for:
setting the path to JS libraries
adding libraries for processing
callbacks when the current object changes or when download occurs

One nice new feature is that the Viewer can be reset to the original perspective; CTRL-RETURN

Both objects (Processor and Viewer) are provided via one source file; openjscad.js. In the new version, all the "settings" have been moved to "options" which can be changed.

By changing the source code
By providing options during construction
During run time by calling appropriate functions, e.g. setCameraOptions(options).
Hopefully, this provides enough flexibility for those needing a slightly different view, etc.

Please try the DEV branch if this functionality is of interest.

Nope. You will have to see the code.

FYI The source code is organized quite differently now.
