[osg-users] how to draw 3d pipe

hi all, I know this problem is not so related to OSG, but there is no better place I can find. What I want to draw is to draw a three-dimensional pipe from a 3d curve with a given radius.The pipe I mean is alike a cylinder,but it is bent. any ideas? thanks in advance.

Re: [osg-users] how to draw 3d pipe

Hi forest, I have done this several times in order to simulate springs. If you have the 3D trajectory, you will also have or you can compute the tangent vector (the one that follows it). For every point in the trajectory, you place a point r units away from it and in a perpendicular direction

Re: [osg-users] Crash in Viewer Destructor

Hi Robert, If I remove the shaders of my scene, the crash disappear. Now, I'm looking at a way to stop the Shaders before ending the viewer. When I need to delete the view, I do : stopThreading(); setDone(true); map-erase(viewer); I though the stopThreading() call would do the work for me

HI Vincent, There really isn't much I can do beyond what I've already said. The stopThreading() should stop the threads, since I don't have the code that reproduces the problem I can do nothing more. Robert. On Fri, Jun 26, 2009 at 7:56 AM, Vincent Bourdiervincent.bourd...@gmail.com wrote: Hi

Putting a call to setGraphicsThread(0) near the top of GraphicsWindowWin32::destroyWindow() prevents the problem. Does this seem like a hack, or should I submit a patch? Is there any reason why a graphics thread should still be running after a graphics window has been destroyed? Cory Cory
