<div dir="ltr">The TestEDLPass example renders all the passes with EDL. I think the solution for you is to change up the render passes. Specifically something like<div><br></div><div>camerapass</div><div> {</div><div> - sequence pass</div><div> {</div><div> - EDLPass</div><div> {</div><div> - sequence pass</div><div> {</div><div> - camera pass</div><div> - lights pass</div><div> - opaque pass</div><div> - translucent pass (if needed)</div><div> }</div><div> }</div><div> - OverlayPass</div><div> }</div><div> }</div><div><br></div><div>Each indent is a delegate of the pass above it. That way the geometry is still has EDL applied to it, but the 2D overlay would not. We probably could use a class to help put this all together as these types of putting-passes-together can be a bit lengthy in code.</div><div><br></div><div>Ken</div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Feb 23, 2016 at 2:18 PM, rich <span dir="ltr"><<a href="mailto:richuitnl@gmail.com" target="_blank">richuitnl@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi All,<br>
I have upgraded VTK 6.1 to VTK 7/OpengL2, my app draws a basic point cloud.<br>
Iam using a vtkSliderWidget/ vtkSliderRepresentation2D* to change the point<br>
size interactively. This works ok, both on 6 and 7. Now I was playing with<br>
the vtkEDLShading and this works fine as long as I hide the Slider. As soon<br>
as I show the slider it crashes in vtkEDLShading.cxx around line 400.<br>
<br>
double bb[6];<br>
vtkMath::UninitializeBounds(bb);<br>
for(int i=0; i<s.GetPropArrayCount(); i++)<br>
{<br>
double* bounds = s.GetPropArray()[i]->GetBounds(); <<<========= HERE<br>
if(i==0)<br>
{<br>
.....<br>
<br>
<br>
So what happens is that the SliderRepresentation shows up as a prop(? sorry<br>
for the noob language) here but this has no bounds, so it crashes on the<br>
nullptr. So I tried to call<br>
SetUseBounds(false) but this did not matter, still crashes.<br>
<br>
So then I recompiled the vtkEDLShading.cxx to:<br>
<br>
// FIX for crash on Slider Widgets<br>
int nBBCount = 0;<br>
for (int i = 0; i < s.GetPropArrayCount(); i++)<br>
{<br>
if (s.GetPropArray()[i]->GetUseBounds())<br>
{<br>
double* bounds = s.GetPropArray()[i]->GetBounds();<br>
<br>
if (bounds != 0)<br>
{<br>
if (nBBCount == 0)<br>
{<br>
bb[0] = bounds[0];<br>
bb[1] = bounds[1];<br>
bb[2] = bounds[2];<br>
bb[3] = bounds[3];<br>
bb[4] = bounds[4];<br>
bb[5] = bounds[5];<br>
}<br>
else<br>
{<br>
bb[0] = (bb[0] < bounds[0] ? bb[0] : bounds[0]);<br>
bb[1] = (bb[1] > bounds[1] ? bb[1] : bounds[1]);<br>
bb[2] = (bb[2] < bounds[2] ? bb[2] : bounds[2]);<br>
bb[3] = (bb[3] > bounds[3] ? bb[3] : bounds[3]);<br>
bb[4] = (bb[4] < bounds[4] ? bb[4] : bounds[4]);<br>
bb[5] = (bb[5] > bounds[5] ? bb[5] : bounds[5]);<br>
}<br>
<br>
nBBCount++;<br>
}<br>
}<br>
}<br>
<br>
And this fixed the crash but now the slider widget is also EDL shaded.<br>
Is there something I overlooked?<br>
<br>
thanks,<br>
