Re: [osg-users] Call for testing, preparing for 3.5.6 dev release again :-)
Hi Robert,
A very minor one, but I've noticed that in
osg::Text::computePositionsImplementation(), any bounding box margins set are
never taken into account when calculating the position of the text, as the
positions are calculated from the bounding box before the margins are applied.
Code:
void Text::computePositionsImplementation()
{
TextBase::computePositionsImplementation();
computeBackdropPositions();
computeBackdropBoundingBox();
computeBoundingBoxMargin();
}
For example if you set the text alignment to LEFT_BOTTOM and set a bounding box
margin, the margin is not taken into account when calculating the position.
Possibly it should be something like:
Code:
void Text::computePositionsImplementation()
void Text::computePositionsImplementation()
{
TextBase::computePositionsImplementation();
computeBackdropPositions();
computeBackdropBoundingBox();
computeBoundingBoxMargin();
// Compute position again to include bounding box margins for non
base-line text alignments
if (_alignment < LEFT_BASE_LINE)
TextBase::computePositionsImplementation();
}
Cheers,
Jamie

Re: [osg-users] Please test OpenSceneGraph master in prep for 3.5.6 dev release
Hi Robert, Another minor observation is that intersections no longer seem to work on osgText. You can see this in the osgpick example when you click on any of the text.

Re: [osg-users] Please test OpenSceneGraph master in prep for 3.5.6 dev release
Hi, I just tested it with windows 10 / VS2013. I had to make a couple of minor changes to the osgcluster and osgbindlesstext in order to get those examples to compile. I've posted the modified files in submissions. It works ok for the most part but I've noticed a few models (which used to work ok with 3.3.5), when loaded now cause all the stats viewer and HUD text to go black. I've attached an example model which causes this on my machine if it's any help.

Re: [osg-users] About Boat Movement
Not sure if you've seen it but there's a simple example in the osgocean example, which just adjusts the floating objects height and orientation, based on the water surface intersection point and intersected geometry normal. It only works for small objects around the same size or smaller than the waves. For larger objects like large boats it wont be at all realistic, so you'd need to do something like whats described in that paper, or at the very least dampen the attitude.

Re: [osg-users] Using OSG, how can I generate and render terrain from grid file format?
Hi, I think you can use Virtual Planet Builder to generate a paged quad tree terrain database from your data. It uses GDAL to read grid data, which I believe supports at least one of the surfer grid formats.

Hi Fabrizio, I'd be interested to see your patches to get osgOcean working with osg 3.4.0. I'm just in the process of trying to get it working. I've changed a few things and got it to compile at least, but there's quite a few glitches, garbled statesets etc. I've had slightly more success with version 1.1 than with the current trunk version.

Re: [osg-users] Qt 5.4 + OSG 3.2.1 + Multithreading
Hi, We're currenltly just embedding our osg window into Qt as foreign windows as decribed here: http://forum.openscenegraph.org/viewtopic.php?t=13602. This has worked well for us since Qt 5.4 although there are a few quirks, notably the lack of keyboard focus in the osg window and also you cant paint over the top with a QPainter. But if you just want to embedd an osg window in a Qt widget then it works fine. No problems with multithreading either. I've tried most of the fixes mentioned above and got them to work at the time, but then ran into problems in later versions of Qt when the cannot access QOpenGLContext in a different thread errors appeared again. I managed to fix the errors for a couple of Qt versions before giving up trying to keep up.

Re: [osg-users] State of Qt5 integration?
Hi, It's good to know you've got it working like this. I've tried your example with windows 7, Qt 5.1 and I get the following Qt error and the osg window doesnt embed into the Qt widget. QWindow::fromWinId(): platform plugin does not support foreign windows. From the Qt documentation (setParent(QWindow * parent): If parent is a window created by fromWinId(), then the current window will be embedded inside parent, if the platform supports it. Window embedding is currently supported only by the X11 platform plugin. I'll try again with Qt 5.2 when I get a chance.

Re: [osg-users] osgearth terrain problem
I'm not very familiar with osgearth terrains but I'm pretty sure the quad tree is made up of something like osg::PagedLOD nodes, each with a TerrainTile and a group of similar child osg::PagedLOD nodes. As each osg::PagedLOD is loaded, the range is evaulated to decide whether to load the next LOD (child). I found the following post very helpful when trying to understand the structure of virtualPlanetBuilter terrains http://forum.openscenegraph.org/viewtopic.php?t=4255 It's a really good way of making quadtrees using OSG which gives very good perfomance on very large datasets Jamie -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=51543#51543 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] [vpb] osgdem --no-terrain-simplification : what exactly is it doing?
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. If you just want a single terrain tile from your projected geotiff, then you could simply create an osgTerrain::TerrainTile using your projected image as a heightmap. You can ignore your NODATA values by setting a osgTerrain::NoDataValue in your TerrainTile's elevationlayer ValidDataOperator.

Hi, I'm having trouble getting my AutoTransforms to start Autotransforming. For some reason I need to manually resize my GLWidget before they start Autotransforming.

[osg-users] (Qt) single GraphicsWindowQt completely filling parent widget
Hi, For some reason I'm struggling to get a GraphicsWindowQt (GraphicsWindowQt ::getGLWidget) to completely fill a parent widget. I've tried various ways and always seem to fail (the GraphicsWindowQt isnt displayed) unless there is a non zero margin on a layout, in which case it works as expected. It's the same for setting the mainwidget of a qmainwindow, it doesnt appear unless I set a non zero margin. I can simply reproduce the problem in the osgviewerqt example with the following modification: Code: QGridLayout* grid = new QGridLayout; grid-setSpacing(0); grid-setMargin(0); Setting either the margin or spacing to something other than zero displays the viewers ok.
