Hi,

I wonder if there is a way to accept image texture and then from a new node? Example

newvrml = 'DEF ROOT Group {';
newvrml +=' children [';
newvrml +=' Transform {';
newvrml +=' translation -2 2 0';
newvrml +=' children [';
newvrml +=' DEF TOUCH TouchSensor {}';
newvrml +=' Shape {';
newvrml +=' appearance Appearance {';
newvrml +=' texture ImageTexture {
newvrml +=' url "imagefile.gif" ';
newvrml +=' geometry Sphere {}';
newvrml +=' }';
newvrml +=' ]';
newvrml +=' }';
newvrml +=' ]';
newvrml +='}';

I tried the above and the browser complains about this line url "imagefile.gif" ';

Is there escape character in vrmlscript? Or is there anyway I can include a gif file? I am using cortona browser. Thanks!

Use
newvrml +=' url \"imagefile.gif\" ';
for the respective line.

The problem is that you have the whole script inside a string.
I.e. the whole script is surrounded by " . And when the browser finds
the " before imagefile.gif it must think that the script ends there.
Then it cannot understand the word imagefile.gif . Therefore you
must quote the " before and after imagefile.gif .
