Re: [osg-users] ViewerQT destruction

2008-07-03 Thread Virginia Holmstrom
I'm not sure how many people can see this because I am not sure how many people use Qt 3.3.3 or if it is reproducible in Qt4. However, I can get objects in a one window to dissapear when another winodow is destructed even when using a different scene. (My previous example used the same scene).

1. Can parallel split shadow map handle an omnidirectional light in the center of a scene? (Such as the sun in the solar system?) Taking the osgShadow example, if I move the positional light setting from far away to within the scene the shadows are not located where one would expect given the

[osg-users] DistanceAccumulator scale

2008-02-25 Thread Virginia Holmstrom
Good morning all- We are using the depth partition node approach and we are noticing issues where our scaled objects are being clipped by what looks like the near and far clipping planes. At times, we will only see the ‘’middle slice” of an object, perhaps the middle slice is as wide as the

This may be a newbie question, but why is there no double type in the definition of array (pasted below)? How does one create geometry specified with doubles if Geometry::setVertexArray can not accept doubles? class OSG_EXPORT Array : public Object { public: enum

All- I am trying to have multiple views into the same scene, which the user can manipulate separately (navigation in one should not affect the display of the other). I want each view to be in a separate window. Right now my second window is not refreshing. I am using QT 3.3. Due to the issue

Hello- We are transitioning to OpenSceneGraph 2.2 from another visualization kit. Has anyone attempted to render the scene in slices in order to improve accuracy and reduce artifacts over very large z distances? I.e. each iteration adjust the near and far clip planes to render a portion of the
