want the laser spot to be nicely circular, but as the surface is a
triangle mesh, the triangle shapes dominate the shape of my laser spot.
The only way I found to make the laser spot nicely circular, was to
greatly reduce the triangle size, w.r.t. the laser spot size.<br></div>The attached picture illustrates the problem.<br><br></div>Is there any solution to smooth the laser spot edge, such that it appears circular, without reducing the triangle size?<br><br></div>In brief what I did:<br></div>I created a vtkLight _laser_.<br></div>I set _laser_ to Positional.<br></div>I reduced the ConeAngle of _laser_ to create a bounded light beam.<br></div>I directed _laser_ at a flat triangle mesh.<br><br></div>Thank you for your help!<br><br></div>Caspar</div>
