How to set the height of a polygon in OSG 3.0?
I have created some polygon which are 2D. I want to assing random heights for
the polygon. How this can be done?
osg::Geometry* polyGeom = new osg::Geometry();
and i then feed the vertices like:
osg::Vec3 myCoords[] =
{
osg::Vec3(-1.0464, 1.0f, -0.193626),
osg::Vec3(-1.0258, 1.0f, -0.26778),
osg::Vec3(-0.807461, 1.0f, -0.181267),
osg::Vec3(-0.766264, 1.0f, -0.0576758),
osg::Vec3(-0.980488, 1.0f, -0.094753)
};
Is there anything like ExtrudeGeometry in OSG?

Re: [osg-users] Fwd: setting a polygon height
Hi Robert,
Is it possible to have a 2D square looks like a cube?
for example I have 2D polygon if I could add a height parameter so that its
look like a cube but faces are polygons. I dont know what are the exact terms
to use to get good response.
hope this image url helps http://i.stack.imgur.com/OnRz3.png

Hi Mohammed,
I'm guessing most of the community like me are rather perplexed by
what specifically you are expecting/looking for. The heights of a
polygon are simply it's z dimenion when you have a coordinate system
with Z up like the OSG defaults. So setting it randomly would just
entail setting the z value, but as your code show you already setting
the xyz values then one would have to guess that this isn't what you
mean at all. This leaves us rather stuck trying to guess what you
actually mean. Mentioning extrusion doesn't help either as this
rather tangential topic, or perhaps in your current view it's not.
Alas we can't jump in your head and know what you are meaning.
The only thing I can say with certainly is to say that the OSG doesn't
have an extrusion tool. The OSG is primarily a scene graph, not a
scene building tool.
Robert.

I seem to recall there are some GIS tools out there for computing flooding, and you could perhaps take the output data of those and visualize it in OSG.

Re: [osg-users] flooding water
chris, I want something similar to osgRiver. I compiled osgRiver and it run sucessfully. But I am unable to install anuga. I want a simple thing. I only want some small modifications to osgRiver. Below are my doubts 1. osgRiver has an island file called river.3ds. how its made? 3dmax? 2. I can load an 3d model of urban area built using osggis there are roads in it . I want to show the flowing on water from one point of city to another. then I need to calculate which all buildings are in water. 3. how to make water flow only through roads or some open areas? .Even though my title is flooding i want to show flow of water or tsunami on urban areas. 4. how to build 3d models for the osg? osgRiver show water flowing only through certain path. how is it done? see results on this poster http://graphics.tudelft.nl/~ruben/PosterI3D2010.pdf 5. what will be the amount of area getting destroyed.(second project) 6. visualize the distorted buildings(third project) I would like to do it as a student project using OSG if not existing. so I need to do some coding for the project or customization of some existing tools maybe osgRiver On Fri, Mar 2, 2012 at 12:40 AM, Chris Hanson xe...@alphapixel.com wrote: http://en.wikipedia.org/wiki/ANUGA_Hydro http://www.mssanz.org.au/modsim05/papers/nielsen.pdf From the paper The animation tool developed for AnuGA is based on OpenSceneGraph, an Open Source Software (OSS) component allowing high level interaction with sophisticated graphics primitives. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Training • Consulting • Contracting 3D • Scene Graphs (Open Scene Graph/OSG) • OpenGL 2 • OpenGL 3 • OpenGL 4 • GLSL • OpenGL ES 1 • OpenGL ES 2 • OpenCL Digital Imaging • GIS • GPS • Telemetry • Cryptography • Digital Audio • LIDAR • Kinect • Embedded • Mobile • iPhone/iPad/iOS • Android ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org -- Regards, Rashad ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

If you want a more accurate volume calculation then you'd have to take
into account the shape of the waves and the seabed.
I *think* one of the properties of the FFT ocean surface is that the
average height will always be zero so you can treat it like a flat plane in
your volume calculation. You might want to check that though it's been a
while since I've looked at it in detail. If that's the case you only need
to take into account the shape of the sea bed in your calculation. It is
possible, but you'll have to work out the maths for that.

To use this you'll need to install NVTT SDK and rebuild VPB against it. When running osgdem you'll need to add the --compressor-nvtt command line option to tell osgdem to use NVTT. Alternatively you could avoid use of OpenGL compressed textures by using the --RGB-24 command option. Or... just install an non broken OpenGL driver. Robert.

To use this you'll need to install NVTT SDK and rebuild VPB against it. When running osgdem you'll need to add the --compressor-nvtt command line option to tell osgdem to use NVTT. Alternatively you could avoid use of OpenGL compressed textures by using the --RGB-24 command option. Or... just install an non broken OpenGL driver. Robert.
