Re: [osg-users] Adding code for movie textures

[Robert Osfield]

Hi Patrick,

Playing movies automatically isn't that what all users will want all
the time, so hard coding this in isn't appropriate.  In the past I've
always just used a custom NodeVisitor to traverse through an enable
the movies, this is pretty straight forward to write and retains
complete control to the application developer. You could place such a
visitor inside a osgDB::Registry::ReadFileCallback to apply the
visitor automatically to all loaded models.

[osg-users] Adding code for movie textures

[Patrick A. Webb]

I've been trying to find a way to get movie textures to play using only a 
.osg file as the input to osgviewer. From skulking around in the source 
code I figured out how "osgviewer --movie" plays movies on a polygon and 
took that idea and applied it to the texture handling source files in 
osgPlugins/osg.


I added the following code to Texture1D.cpp, Texture2D.cpp, Texture3D.cpp 
and TextureRectangle.cpp:


#include "osg/ImageStream"



if (fr[0].matchWord("movie") && fr[1].isString())
{
std::string filename = fr[1].getStr();
Image* image = fr.readImage(filename.c_str());
ImageStream* imagestream = dynamic_cast(image);
if (imagestream) {
texture.setImage(imagestream);
imagestream->play();
}
}



So far it's worked. Is this something that's going to work out in the 
long run? Is there a better way for me to do what I've done?
