Hi Tony,

I think it just converts LOD nodes to PagedLOD, but it doesn't index and
spatialize data that isn't already.
I don't know what organization the PLY loader puts on the data, so what you
get is highly dependent on how the PLY loader constructs the scenegraph.

How do you use the pagelod example then?

However, this depends on octrees from PCL. I'll think on some alternative
using OSG only. Does OSG implement anything like this?
Robert: Thank you for your tips. I will make sure to be more specific in
the following posts. Howe

Hi all,
Just to be clear, what you're seeing in that video is a separate library
for dealing with massive point clouds that we've developed here at Pelican
Mapping. It works great with osgEarth (as you've seen in the videos) but
it's not part of osgEarth itself. The point cloud library isn't cur
Bruno, I'm guessing you're dealing with geospatially-oriented point clouds.
You should probably consider working with osgEarth, as it already has an
infrastructure for indexing, paging/loading and rendering LIDAR geospatial
point clouds. Here's a video of it in action:

Hello,
I deal with huge point cloud data and I am rendering it the naive way (via
VBO or display lists)
However, I've seen software (e.g. Photoscan) do this via some kind of
progressive loading (based probably on the distance to the points and point
density). I think this is similar to pagedLOD b

The plug-in you used to load your model may behave differently and as a
result the scene's bounding sphere center could have shifted

Hi Ronny,
I don't recall any specific changes to view matrix management between
OSG-3.2.1 and OSG-3.4.0. I'm also not aware of any bugs being reported
that look relevant to this what you are describing.

Hi,
I have some code for doing picking of objects on the screen:
Code:
float dX = ea.getX();
float dY = ea.getY();
osg::ref_ptr camera = view->getCamera();
// compute model to window transform
// Model*View*Projection*WindowMatrix
osg::Matrixd matrix;
matrix.postMult(camera->getViewMatrix());
17 matches
