<p class=MsoNormal>Hello,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m little stuck on how best to approach this problem.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have a Collada object, which is a box with a light bulb
inside that animates out. <o:p></o:p></p>
<p class=MsoNormal>All I want visible is the opening of the box so you can see
inside it.<o:p></o:p></p>
<p class=MsoNormal>I don’t want to see the external faces of the box. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>You would be able to see more of the light bulb, and inside
face of the box, as the angle of the object changes to face the camera.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I suppose the top part of the box works as a viewport to the
innards. I've attached an image to explain it better:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Given that I’m using an animated 3D Collada object;
which contains the box and light bulb – is this possible?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Is there a special technique I need to employ at the 3D
model building stage, or<o:p></o:p></p>
<p class=MsoNormal>Can I mask the external parts of the box and the innards
they cover, or<o:p></o:p></p>
<p class=MsoNormal>Is the solution to the problem some kind of custom dynamic
ViewPort – and if so, how complex is this?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Kind Regards,<o:p></o:p></p>
