<p dir="ltr">I wonder if we should develop a X3D JSON parser which shows streaming parsing of X3D JSON for large files. Getting a large file which our current tools don't support would be a good idea.</p>

Another thing you can do is parse the JSON, then insure the first *object* has an "X3D" key. Good luck!</p>

Hi Don and John,<br>
<br>
Sounds like you are making excellent progress on JSON.<br>

thanks. updated the description page today, not many TODO items left.<br>

So, I am just thinking ahead, to maybe one day getting JSON to load directly into my C++ Viewer. I am thinking of a loader, and asking myself the following question:<br>
<br>
Apart from the .json file extension, is there any other definitive way of determining that this is, or is not, a JSON X3D file. I am looking at your HelloWorld.json example, and seeing the text<br>
<br>
{ “X3D”: {<br>
<br>
on the first line. So, I’m thinking that the initial test that it is a JSON X3D file goes as follows:<br>
<br>
1)Is the first character a left brace?<br>
<br>
2)Ignoring white space, is the next token the quoted string “X3D”?<br>
<br>
3)Ignoring white space, is the next token a colon?<br>
<br>
4)Ignoring white space, is the next token a left brace?<br>

<br>
yes to all<br>

That is the equivalent of reading the header line. By the way, is it permitted to have white space before the first left brace?<br>

<br>
yes<br>
<br>
i went ahead and experimented with the Netbeans plugin JS CSS Minify Compress, available via Netbeans/X3D-Edit Tools/Plugins menu and described at<br>

<br>
this also showed that getting rid of all intermediate whitespace was OK.<br>

I guess I just want to know that my thinking is not incorrect – double negative intended.<br>

no response :)<br>
