Osg mesh how to add LOD

[brunomartelli]

ive tried this:
http://docs.worldviz.com/vizard/Frequently_asked_questions.htm#1_6

to add LOD meshes to my main mesh but doesn't seem to work. Anyone know how to???

thanks

[brunomartelli]

add the LOD helper, set it to the origion of model, call your LOD meshes LOD01, LOD02 etc. put them into the slots. The max min numbers indicate when the LODs will switch. so first would be say 0 - 500, second 500 - 1000 etc. The number is distance to viewer. empty slots will show up nothing, so you can make the mesh completely disappear

Select all the models and the LOD helper. export osgb, in export options select Export Helpers.

IDK how to change the LOD swap distance in Vizard (i woould love to know)

[brunomartelli]

any ideas about how to set the LOD swap distance?

[Jeff]

I'm not sure if this is possible to change from Vizard but I'll look into it and get back to you

[Jeff]

The LOD ranges can be edited in Inspector with Vizard 5. Currently, there is no built-in interface for editing them within a script.

Thanks, I'm using a CAVE at Christie Digital in Canada, they have vizard 4. Can I use 5 to edit the LOD then run in the setup they already have?

[Jeff]

Yes, you can save out the model after editing the LOD ranges in Vizard 5 Inspector. Then load the model in Vizard 4.

[brunomartelli]

thanks Jeff, would you advise me to try Vizard 5 in the CAVE? would that be painful?

[brunomartelli]

..actually the model wont load in Vizard 4 it says"ERROR: 'TerrainTestsSetof8/C1.OSGB' was generated by a newer version of Vizard, and is incompatible with the current version."

[brunomartelli]

Yes, you can save out the model after editing the LOD ranges in Vizard 5 Inspector. Then load the model in Vizard 4.

have you a tip for this Jeff? Vizard 4 wont accept it, am i doing something wrong?

[masaki]

Actually a model modified/saved in Vizard 5 Inspector can not be loaded into Vizard 4. You will have to load it into Vizard 5.

Best,
Masaki

Can I put vizard 5 on my CAVE without breaking anything?

[Jeff]

Yes, Vizard 5 will install side by side with Vizard 4 and not break anything.
