Hello,
does anyone know how to rotate a SphereSegment such that it's oriented
correctly in another "part of the world.?"
I do not and I really need the help. I have tried using
MatrixTransform and PositionAttitudeTransform as the transform to
attach a SphereSegment to to get it to rotate correctly.
But all I get is a sphere in the middle of "no-where" when using the
PositionAttitudeTransform - it simply translates the spehre to some
unknow part of the universe
And with MatrixTransform, all it does is swing the SphereSegment around
in a circle on the same axis. I can not get it to perform a correct
roll, pitch, yaw rotation. Here is the code I'm using: (would someone
be so kind as to tell what what I'm doing wrong? Thank you.)
*****************************************************
osg::MatrixTransform *DrawRadar(double x, double y, double z)
{
osg::MatrixTransform *radarXform = new osg::MatrixTransform();;
// Intersect Radar with Terrain
//
osg::Vec3 v3(x,y,z); // SPHERE CENTER
osg::ref_ptr<osgSim::SphereSegment>
radarSphere = new osgSim::SphereSegment(
v3, // position
510.f, // radius
osg::DegreesToRadians(0.0), // azMin
osg::DegreesToRadians(360.0), // azMax
osg::DegreesToRadians(0.0f), // eleMin
osg::DegreesToRadians(35.0f), // eleMax
60); // density
if (radarSphere.valid())
{
radarSphere->setAllColors( osg::Vec4(1.0f, 1.0f, 1.0f, 0.5f) );
radarSphere->setSideColor( osg::Vec4(0.0f, 1.0f, 1.0f, 0.1f) );
}

std::cerr << "radarSphere is invalid" << std::endl;
osg::Quat orientation = defaultOrientation;

Hi All,
based on osgParametric-example i try to get a vertexshader to update a
Uniform from a sum of perVertex-operations. I tried to read the result back
into the application. While there is no problem to "feed" the VertexShader
with updated values from a UniformCallback, i can't update a uniform inside
a shader and use the value per frame in the osg-application.
Is it possible to assign/increment a Uniform-value inside of a vertex-shader
and read the result per frame in the osg-application? Maybe there are some
examples showing how to solve this ?
Thanks for infos.
Markus

Hi Jan,
Thanks for telling that osgCal2 is mature. I've made my choice and use
osgCal2.

Hi everyone,
I have a simple question. While looking for an integration of cal3d into
osg I found 2 solutions: osglCal and osgCal2.
Which one is the best to use? Are they both as active in development?
For
instance, are they both using cal3d-0.11. I am pretty sure that osglCal
is
using 0.11 since it is being supported by Loic Dachary. Is this right?
Both are using 0.11. I do not know about osgCal, but osgCal2 is stable,
thus not much development is happening - the library does what we wanted.
The fundamental difference is that osgCal is licensed under GPL, osgCal2
is using LGPL, be careful about this if you are planning something
non-GPL with it.
There is a third solution as well - ReplicantBody which builds on top of
Cal3D.
Regards,
Jan

Yeah, I've tested this database on many different computers (not every test
of course). Nvidia, ATI, Intel, AMD, SLI, etc.
Does anyone know how textures are shared? Say I have 4 files that all have
the same texture embedded in them: A.ive, B.ive, C.ive, D.ive. Or I have
one file that contains all the geometry of A, B, C, and D with the one
texture embedded in it.
1) A.ive,B.ive,C.ive,D.ive -> 4 duplicate textures
2) E.ive contains A,B,C,D geometry -> 1 texture
This also will apply to shared geometry. Say I have a light bulb model that
is in each of the A, B, C, D ive files. Is the geometry for the light bulb
reloaded 4 times?
This may be a factor. My paged database contains a lot of duplicate
textures, and geometry. This is why I was asking if there is anyway to
create an ive file that doesn't contain embedded textures.

Hi Robert,
One other thing apparently was a factor in fixing the hitching problem
I was having. I had to generate the database with larger tiles. I
used to have a checkerboard database of tiles, and each tile had about
4 paged files in it. If I condense those 4 paged tiles into one large
one, then I get better results. Here is the investigation:
This seems counter-intuitive.
My experience has been that more, smaller pieces usually compile/download
more smoothly.
I am not sure where to continue investigating.
I don't recall, have you tested this on a computer with a significantly
different configuration? Different CPU and/or graphics card?

I'm trying to use the stencil buffer, so I setup the subgraph with a
ClearNode as the root of the subgraph. When the cull visitor traverses
the graph, it is setting these values for the top level, which is
removing the calls to the GL_COLOR_BUFFER_BIT and GL_DEPTH_BUFFER_BIT.
Is there a way to get around this problem? Anyone else have this same
problem?

I have derived a node from osg::Image to add some custom behavior. However,
when this node is written out it is written as a base osg::Image and my
custom behavior is discarded. How do I write out my extra fields and
read them in again within the osgPlugin architecture? I am mostly interested
in the .osg plugin and the .ive plugin. If the answer is "modify the source
code in your local copy of the osg source repository" then I might have to
rethink my approach to this problem.
