<div dir="ltr">Hi Daniel,<div>The pagedLOD displays the lower lod level until the requested level is loaded, I think wat you see is caused by the lowest LOD level being empty. We use almost all our pagedLODs with a permanent base level:</div><div>in .osg format this looks like this:</div><div><div>PagedLOD {</div><div> RangeMode DISTANCE_FROM_EYE_POINT</div><div> RangeList 2 {</div><div> 120 10000</div><div> 0 120</div><div> }</div><div> NumChildrenThatCannotBeExpired 1</div><div> FileNameList 2 {</div><div> ""</div><div> stationwagon_gray_HQ.ive</div><div> }</div><div> num_children 1</div><div> ProxyNode {</div><div> FileNameList 1 {</div><div> stationwagon_gray_LQ.ive</div><div> }</div><div> num_children 0</div><div> }</div><div>}</div></div><div>or using a lower resolution texture (my mip pseudoloader skips the top level mipmaps from textures)</div><div><div> PagedLOD {</div><div> DataVariance STATIC</div><div> nodeMask 0xffffffff</div><div> cullingActive TRUE</div><div> Center -37000 -48000 0</div><div> Radius 11313.7</div><div> RangeMode PIXEL_SIZE_ON_SCREEN</div><div> RangeList 2 {</div><div> 0 1448</div><div> 1448 1e+037</div><div> }</div><div> NumChildrenThatCannotBeExpired 1</div><div> DisableExternalChildrenPaging 0</div><div> FileNameList 2 {</div><div> ""</div><div> 560205_16km_L11.osg</div><div> }</div><div> num_children 1</div><div> ProxyNode {</div><div> nodeMask 0xffffffff</div><div> cullingActive TRUE</div><div> ExtRefMode DEFER_LOADING_TO_DATABASE_PAGER</div><div> Radius -1</div><div> FileNameList 1 {</div><div> 560205_16km_L11.osg.1.mip</div><div> }</div><div> num_children 0</div><div> }</div><div> }</div></div><div>Regards, Laurens.</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Jan 24, 2017 at 8:29 PM, Daniel Lazaroff <span dir="ltr"><<a href="mailto:lazaroff_daniel@yahoo.ca" target="_blank">lazaroff_daniel@yahoo.ca</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">greetings all,<br>
<br>
I've started trying out the DatabasePager with a test model of a small city landscape (openflight file) that has been converted into pagedLODs (I'm experimenting with load balancing of VRAM usage).<br>
I used the "osgpagedlod.cpp" example to convert and write out the individual files (.ive). I'm using OSG 3.2<br>
The individual buildings have discrete LODs and do not have overlapping ranges. As I move around the scene using the osgGA::TerrainManipulator,<br>
they pop in and out of the rendered scene, for a few frames no LOD is displayed. (due to the load time from disk of the files most probably)<br>
<br>
Is there something that I can do to alleviate this (tricks or tips)? I could try to overlap the ranges, but I read somewhere that this is not suggested.<br>
<br>
Thanks for any info.<br>
Cheers<br>
<br>
Daniel<br>
