Add Score::toJson and a JavaScript class for displaying that JSON as a 3-D piano roll #191

Closed gogins closed 2 years ago

gogins commented 2 years ago

The purpose is to enable using the C++ CsoundAC library or other C++ code to generate scores using the Clang opcodes, and then to call JavaScript in a Web page created with the WebKit opcodes for displaying that score as a three-dimensional piano roll.

I am now getting a JavaScript score into the browser, using a lame polling hack. So now I can move ahead.

I think it will suffice to enqueue scripts from the webkit_run_javascript opcode until the load_finished state is signalled by callback. Then the scripts can be executed.

Working now but would prefer an alternative to animate, and the grid size and score bounding box size don't seem to match.

This is all fixed now. I was using the wrong field of the JSON events for time. Animate is fine, it can be throttled.
