Hello Dmitri,<br><br>Yes of course it is possible. Take a look at the vtkLight documentation here:<br><a href="http://www.vtk.org/doc/nightly/html/classvtkLight.html#details" target="_blank">http://www.vtk.org/doc/nightly/html/classvtkLight.html#details</a><br>
<br>Consider to set the light position, focal point and cone angle then call SetPositionalOn().<br><br>Hope it helps,<br><br>Regards,</blockquote><div><br></div>There is a shadow example here:<div><a href="http://www.vtk.org/Wiki/VTK/Examples/Cxx/Visualization/Shadows">http://www.vtk.org/Wiki/VTK/Examples/Cxx/Visualization/Shadows</a><br clear="all">
<br></div><div>If you could extract just what you said (a light making a circle on a plane) into a simple "Light" example, that would be a nice addition to the examples!</div><div><br></div><div>David</div></div>
