I've written code before to page massive rendered images out to the final
image file on disk as they are generated, so you could render bigger output
than what you have RAM for.

Hello!You reale need OSG 3.5 and MSVC2015?For experiment you can try OSG 3.4 vs MSVC2013 from DaD's
Hi,
I have downloaded openscengraph from git(master) and I have succesfully
compiled and installed osg on windows 10-64bit using VS 2015. Now I want to use
OSG lib and include with my own application using CMake 3.5.1. I have set var
OSGDIr and cmake can find include but cannot find static
Hi,
Depends on what you want to do. If you want to render big resolution image, you
would have to use tiled rendering. Using PBO for transfering data back could
help speeding things up. But in most cases you are rendering non RT image (its
too big you cant even save it in RT). Then you just
HI Filip,
The osg::CoordinateSystemNode is a data container node that stores the
coordinate system details of it's subgraph. It's use is passive, other
functions in the OSG or client apps query the CoordinateSystemNode to find
out what coordinate system it's subgraph is in. So if you generated
Hi,
I did, but it seems to me, that this is only offline transform - exact same
thing that proj does. I want to transform points "on the fly". Can I somehow
use Helmert transformation (from +towgs84 proj param) ? I dont need to
transform between multiple systems, just to wgs84 would be nice
Hi,
It really depends on how big your point cloud is. General rule is to create
tree (kd-tree, octree, ...). Either multiple nodes or on big custom drawable
with tree in it. If you create custom drawable, you can test if ray intersects
tree node or polytope contains tree node. If you create
Filip,
osg::CoordinateSystemNode does not do any transformation. It is really just
a container to hold information about the spatial reference of the data
underneath. Furthermore, no, a 4x4 matrix not sufficient for geospatial
reprojection. You will need to use the PROJ library for that.
FYI, in
Hi,
I'm working on a project for displaying geospatial data. I usually have data in
some coordinate reference system. What I want now is transform them into
another coordinate reference system (wgs84). Its not a big problem transforming
coordinates on load or preparing data, but I would like
Hi Etienne,
It's not possible to know exactly where the problem lies without knowing
the ordering of how you are setting up the osgViewer and associated Camera.
The best I can say it sounds like the src/osg/DisplaySettings.cpp values
are being utilized after your code is setting up the
Hi,
Everything is in the title, in my application when I set OSG_NEAR_FAR_RATIO as
a runtime environnment variable, the settings I give to my master camera
through a Frustum projection matrix are ignored (and of course I used
setComputeNearFarMode(DO_NOT_COMPUTE_NEAR_FAR) on this camera).

thanks Alistair! That is it

I think this is what you’re after:
https://github.com/XenonofArcticus/OSG-Transparency-Tool
I made a note of it at the time, but haven’t got round to investigating it yet.

Hello Community,
I can recall a work has been done by someone from the community (probably a
lib, can not really remember) that suppose to make the management of
transparent objects in the scene better then the default one. Anyone
remembers the work of the lib/project...?
Thanks a bunch a always

Hi,François
Thank you very much for your reply.
However I failed to build your sample.
The error happens on the line 259, and displays such as

The problem line is
