[osg-users] Trouble Accessing Open Scene Graph Website/ Tutorial

Hi, The website doesn't seem to load. Is it just my system or does that seem to be the case for everyone? Also when I go to the tutorial page and try to download the OpenSceneGraph.zip file it redirects me to Joe Sullivan's homepage! Does anyone know what's going on? Also, is it possible to

[osg-users] Moving Pyramid in Real Time

Hi, I want to move a pyramid based on a defined path (X,Y,Z) of its peak and the Roll, Pitch, Yaw. I have the details of X, Y, Z, Roll, Pitch, Yaw coming from another c++ code and is updated in real time. Does anyone have any suggestions as to how to go about moving it in OSG without the

Re: [osg-users] Bizzare setViewMatrixAsLookAt behavior !!

Hi, What is happening is that the eye instead of being fixed at say (X1,Y1,Z1) is revolving around that point in a small circle while pointing to the correct center! Thank you! Cheers, John -- Read this topic online here:

[osg-users] Collision Detection

Hi, I am trying to implement a code that detects collision between a PAT Node with the geometry of a pyramid and multiple other fixed Nodes that are loaded with ac3d models. How do you determine which node (if any) falls within the geometry of the PAT Node of the pyramid? Thank you!

Re: [osg-users] Collision Detection

Hi Paul, I only plan on detecting intersections between a PATNode and other Nodes. I do not intend to write code for a reaction to a collision, I want the intersection to happen and only want to know which objects are intersecting. Do you suggest I still use osgbullet for that? Thank you!
