using viewer.frame() instead of viewer.run() solved it! How do I remove the default camera manipulator? Do I remove the corresponding event handler? Paul Martz wrote: If you have a Camera manipulator attached to your Viewer, it will override any changes to the Camera matrices. Viewer attache

[osg-users] LOD problems using OSG with TerraPage

Hi, I'm using OSG viewer to see a txp terrain generated by Terra Vista. I have 10m and 1m imagery, with multiple LODs. I noticed that when I'm doing low level flying using OSG viewer, my most detailed LOD sometimes switches to the 2nd LOD. I'm flying just above the terrain, so it is quite impossi

Re: [osg-users] Setting the camera matrix for a viewer

If you have a Camera manipulator attached to your Viewer, it will override any changes to the Camera matrices. Viewer attaches a Camera manipulator by default. Paul Martz Skew Matrix Software On Feb 17, 2008, at 5:31 PM, Per Rosengren <[EMAIL PROTECTED]> wrote: > Hod do I set the camera mat

Re: [osg-users] another one - osg and C#

Sherman, With C++/CLI and its IJW ("It Just Works") interop, you don't run into the issues you do with C#. C++/CLI is a superset of C++. That said there are a couple things to keep in mind: First, C++/CLI lets you mix managed and unmanaged C++, and there are some restrictions in how you are allow

Glenn, That seems like a great design choice, thanks for your insight. It's always nice to get another perspective. Thanks! Jason On Feb 17, 2008 1:09 PM, Glenn Waldron <[EMAIL PROTECTED]> wrote: > Jason, > > Architecturally I will usually treat the OSG API as a low-level > implementation det

Re: [osg-users] another one - osg and C#

Jason, Architecturally I will usually treat the OSG API as a low-level implementation detail. So rather than a thin layer over OSG, I usually will encapsulate OSG code inside controller interfaces that accompany the OSG .NET Control. So for example, there will be a single C++/CLI assembly that wi

Re: [osg-users] another one - osg and C#

Glenn - ever run into any issues where you found portions of OSG not to "work" with C++/CLI? I believe the OSG/C# folks run into this a lot. Any odd difficulties or does everything just work? Follow-up question - have you written any OSG/C++/CLI WPF apps? Winforms? How well does all this stuff "pl

Re: [osg-users] Adding nodes to the scene while theviewer is running

Yes you can add new objects to your application whiles its running all you need is a pointer to your scene graphs and use addChild on that node The man caveat is that you cannot do this in the cull or draw so you have to add your objects before the CULL and draw are dispatched. Also make sure yo

I too need to show images. Since osg is (and should be) 3d-based, the way to do is seemed to be to display a rectange Geometry infront of an orthographic camera, and set the rectangle texture to be the image. Instead of this, I chose to use OpenCV (CV for Computer Vision), but you can also use

Re: [osg-users] another one - osg and C#

Hi Glenn, We're using c# and OSG as well, but we're using hand crafted wrappers that attempt to expose all of the OSG functionality to C# (like the osgDotNet wrappers). This works well for the most part, but I often feel that sometimes it is more complicated than it is worth. I've also written a
