<div class="gmail_quote">Hi all, and especially John,<br><br>I noticed that this code in vtkPointSpriteMapper.cpp 1060 is commented out<br><br> switch (this->BlendMode)<br> {<br> case Accumulate: {<br>/*<br> glDisable(GL_DEPTH_TEST);<br>
glDisable(GL_ALPHA_TEST);<br> glEnable(GL_BLEND);<br> glBlendFunc(GL_SRC_ALPHA, GL_ONE);<br>*/<br> break;<br> }<br><br>I'm setting the Actor's opacity. When commented, the blend-accumulate mode doesn't seem to work (it looks the same with or without blend-accumulate).<br>
<br>When I uncomment this code, it appears to work brilliantly and as I had imagined. Although the depth test probably would make it look less like its "superimposed" onto the rest of the scene.<br><br>Why is this code commented out?<br>
<br>thanks,<br><font color="#888888">Paul<br><br>
