I think my graph is correct. what am i missing?
Honestly I'm not sure if understood all the details of your structure,
but I think that regardless of the details the easiest way to get what
you want is using traversal masks. You can set a 32 bit mask on each
Node and on the Viewport, and only if the & of the masks is !=0 is the
Node rendered. This should give you more control than the Switch.
A fine thing, these masks, but they do not solve my problem:
I try to explain it again:
I got some leaf nodes in my LOD² (Leaf under Lod under Lod) Subgraph.
These LeafNodes are only drawn if the camera is near enough. Fine.
But I want to be able to only draw a subset of these leaf nodes (e.g.
the ones with Textures).
As these are only a few (58 out of 400) they should always be visible.
That has now been "solved" by costly setting all the LODs distances to
INFINITY / back to their desired Values, when switching visibility modes.
I thought their would be a nicer way of doing this.
I tried to have a second "root", where all the texturedNodes ADDITIONALY
get "listed" :
beginEditCP(texturedCubesRoot);
texturedCubesRoot->setCore( Group::create() );
texturedCubesRoot->addChild( texturedCube);
endEditCP(texturedCubesRoot);
and switch between the LOD structure and the flat texturedCubesRoot.
Here lies the problem: The nodes under texturedCubesRoot never get drawn.
Another thing:
how do I "pick" objects correctly with LODs in my Graph? it seems that
sometimes a coarser detail level than is rendered is reported to have
been clicked upon.
Hope this makes things clearer,
