Re: [osg-users] Unit tests

Hi Vincent, Delta3D uses cppunit, and we've been using this library as well for our unit tests. It offers nice macros to run and check the tests, makes it easy to launch a whole suite of tests or only a part of them (via namespace) and optionally prints results on an xml file, besides the cons

[osg-users] how matrixTransform works?

Hi, everybody Could someone explain me how matrixTransform works? In the updatecallback, I set the matrixTransform like this static float c = 1.0; c = c + 0.01; mt->setMatrix(osg::Matrixf::translate(-bs.center()) * osg::Matrixf::scale(1.0, c, 1.0) osg::Matrixf::transla

[osg-users] Ask for osgviewerMFC memory consumption explanations

Hi osg-users, I'm developping an application based on the example "osgviewerMFC" but I don't understand the memory consumption from this example. 1) when I launch osgviewerMFC.exe the memory used is about 10Mo 2) then I open a model, memory rise to let's say 50Mo (depends on the model) 3) then I

hi Roland, thanks for your answer. what i would like to do is to use the extra nodes to store arbritrary metadata associated with my geometry instances as defined in the collada spec maybe by using an additional xml-schema or just by inserting plain text into a param-node, see collada spec (ht

Hello Danny, I'm trying to move my camera forward and backward as the event of up/down key. You're on the right track with your subclass of osgGA::GUIEventHandler. This class's handle() can set the camera's view matrix using camera->setViewMatrix() (or the convenience setViewMatrixAsLookAt()

Re: [osg-users] Geometry Culling

Hi CG, I've uploaded a video http://www.youtube.com/watch?v=X4xgFzaBBWs to show the problem I'm facing when rendering a geometry. Any advices? Yes, that's most definitely z-fighting. Try moving the geometry higher above the terrain, or setting the near and far planes as close to each other

Re: [osg-users] How to decode .ive file?

Hi Akilan, My terrain DB contains lots of .ive files(binary files). I want to decode the file in program to know about its children's details. This I want to do before running my viewer. Is OSG provides interface for such activities? You can convert .ive to .osg with osgconv: osgconv in.

Re: [osg-users] setUpdateCallback fails under slave-camera

Hi Robert, I'm picking up this somewhat outdated topic since we are having a similar problem. We need to render some of our geometry with a separate depth buffer because of precision issues: In the first pass, we are rendering a very large landscape that was created using VirtualPlanetBuilder.

Re: [osg-users] [osgPlugins] how to use extra nodes of collada files?

Hi Jason, the only custom node data that is currently supported is the node description that is read and written as extra data. This might be sufficient and is compatible with how openflight allows custom node data, which was one of my goals for the OSG specific Collada extensions. One other
