Hi Goj,
I think you are almost there: you don't use BUILD_DOCUMENTATION as a
make target, but you have to set it in CMake instead.
You can either activate the BUILD_DOCUMENTATION variable inside CMake
(using ccmake or cmake-gui), or just in the command line with
cmake -DBUILD_DOCUMENTATION=ON
Hi Alberto,
Thanks for chiming in.
I have no 'doc_' targets in my top level makefile, but I see the bits in
CMakeLists.txt, so I tried:
cmake BUILD_DOCUMENTATION .
I get several messages about missing packages, (Freetype, JPEG, Jasper, ... )
which I will fix, but it gives no errors. After

Hello Rebert,
Thank you very much for your explanation, as I am knew to OSG, this really
helps a lot :)
My monitors' order is exactly as you mentioned.
Since I am just getting started, I don't really need multi-monitor rendering,
so after toying with the viewer class, I found out about
Robert,
The issue was I was setting a tileLocator, but I wasn't setting a
layerLocator. That was problematic in the following block of code:
Locator* layerLocator =
_volumeTile->getLayer()->getLocator();
if (tileLocator==layerLocator)
{
If you're just updating an existing array, you don't need to call
setVertexArray (etc); but you need to mark it dirty by calling
m_vertices->dirty();
That applies also to your other buffer objects (color array, elements, etc.)

Greetings everyone,
I am trying to display a point cloud, consisting of vertices and color with
OpenSceneGraph. A static point cloud to display is rather easy with this guide.
But I am not capable of updating such a point cloud. My intention is to create
a geometry and attach it to my viewer
Hi Community,
I am aware that this question is not that much related to OSG (maybe?) but
I count that on the list there are good GLSL engineers.
I am facing issues with enabling this extension ''GL_ARB_gpu_shader_fp64".
It is enabled in my shaders '#extension GL_ARB_gpu_shader_fp64 : enable',
Hi Alex,
I haven't heard of the invert throwing a seg fault before. The stack trace
doesn't have any info about line numbers so we can't say what specifically
was amiss.
The only code in MultipassTechnique.cpp that calls Matrixd::invert() is:
Locator* tileLocator =
Hi Soulaymen,
By default the osgViewer::Viewer calls View::setUpViewAcrossAllScreens() as
a fallback if no windows have been assigned to viewer when viewer.realize()
or viewer.run() is called. The setUpViewAcrossAllScreen() detects how many
screens you have on your system and then opens up a
11 matches
