Hi,
Can you explain what you mean by dynamically linking the node ?

Hi George,
On a first read your LogFileHandler looks OK, the Mutex should in
theory resolve multi-threading issues. From the details you've
provide one can't pinpoint what the problem might be so you'll need to
work through iteratively to see what the problem areas might me. One
test I'd do is

Hi Peter,
KdTree is currently only handles line segment intersections, this is
provided directly in the internals.
To implement other types of intersections one would either need to add
it directly to KdTree as has been done with the line segment
intersection or have an external traverser class
Hi Christian,
With rendering applications you almost always want to avoid just
created data before rendering as this causes a frame stall when it's
most critical. It's best to create the data and set all the values as
much as possible on start up.
As for the expense of osgText::Text, I'm afraid
Hi Ethan,
VPB is built around the idea of creating large paged database, scaling
up to terrabytes in size, rather than single tiles, and render the
terrains at a solid 60Hz. These requirements mean that one has to
tile and LOD the terrain, which is where the default size you are
seeing is coming

Hi Eric,
I could be that you are updating the nodes position after the
osgParticle classes have executed. You don't say how you've
constructed your scene graph and how you update so there is little
others can recommend specificallly.

I'd suggest attaching a texture with a GL_RGBA32F_ARB internal format to
the camera as well (in addition to the image). I'm not sure you are

You should use multiple View's within a single CompositeViewer for
doing this rather than multiple viewers.

When you mention default size I assume you are referring to the 63x63 pixel

default size values; am I

You could also prevent the trackballmanipulator from being created and used by
doing something like this:
Code:
osg::Camera* cam = viewer.getCamera();

Hi,
If you increase the -l numOfLevels argument to 4, you'll at least preserve
all the original heightmap points at the highest LOD tiles when you zoom in
(albeit in a series of tiles). If you search for 64 instead of 63 you'll see
where the default tile size is coming from.
