[osg-users] osg newbie question: billboard with multiple drawables?

Hi, I'm hoping someone can help. I'm trying to develop an in-scene 'label' for my 3D objects (consisting of text and geometry). I was hoping I'd be able to use the osg billboard and add my geometry and text to it as drawables, but I now realise that each drawable will have its own pivot point,

Re: [osg-users] osg newbie question: billboard with multiple drawables?

Hi Paul, The easiest way to do it is use an osg::AutoTransform, this is like a Billboard but can rotate to screen a whole subgraph rather than just drawables. Billboard is lightweight for things like trees, but AutoTransform is more flexible. Robert. On Tue, Sep 28, 2010 at 11:03 AM, paul

Re: [osg-users] map text to geometry

Hi Katja, osgText uses a texture atlas to store it's glyphs and separate quads to pull out the correct part of the texture atlas to get individual text characters, this makes it impossible to just pull the text texture directly and apply it to an ordinary geometry as the texture coordinates would

[osg-users] Problem loading images when migrating to new OSGViewer

Re: [osg-users] Load of 8 bits image for creating texture

Hi Adrien, When using multi-texturing you need to decide which texture units to use then set up your texenv (if using fixed function pipeline) or shaders to reflect this. Typically, in your case, one would use texture unit 0 and texture unit 1, so you'd do something like:
