<p class="MsoNormal">I have a few questions about how to build a driver to do some specific tasks in osgEarth.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Simple example. <o:p></o:p></p>
<p class="MsoNormal">Using simple ocean as an example replace the texture piece with geo-spacial image and then build a shader to add effect to the image.<o:p></o:p></p>
<p class="MsoNormal">Ie. Arrowed line that changes color in towards the direction a path should be followed start to end.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The shader piece can be figured out by us working with the shader code.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The part I am having issues with is adding an arrow image or geometry polygon of an arrow to the map at the position I need it at to run the shader effect on.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is this the correct place to aske this sort of question or is there a different mailing list or thread I should use to get help with getting this designed.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you in advance<o:p></o:p></p>
